Detect if an armor header matches 2440bis-21. (parse_header_line): Call it here, as bis-21 requires warning the user (but continuing to process the message) when seeing an unknown header. * encode.c (encode_crypt): Missed one call to setup_plaintext_name(). This is bug#809. * sign.c (mk_notation_policy_etc): Expect all sigs that this is called for are >=v4. (write_signature_packets, make_keysig_packet): Only call it for >=v4 sigs.

This is so that we can install helpers from 1.4 and 2 without conflicts and first of all don't get lost with weird bug reports. * keyid.c (serialno_and_fpr_from_sk): New. Actually lost during the last 1.4 to 1.9 merge. * gpg.c (list_config): Output ccid-reader-id only for gnupg 1. * call-agent.c (agent_scd_writekey): New.

The check should only happen on the sk side. Noted by Dirk Traulsen. * keygen.c (gen_card_key): Add optional argument to return a pointer (not a copy) of the stub secret key for the secret key we just generated on the card. (generate_card_subkeypair): Use it here so that the signing key on the card can use the card to generate the 0x19 backsig on the primary key. Noted by Janko Heilgeist and Jonas Oberg. * parse-packet.c (parse_user_id): Cap the user ID size at 2048 bytes. This prevents a memory allocation attack with a very large user ID. A very large packet length could even cause the allocation (a u32) to wrap around to a small number. Noted by Evgeny Legerov on full-disclosure. * keygen.c (gen_dsa): Allow generating DSA2 keys. Allow specifying sizes > 1024 when --enable-dsa2 is set. The size of q is set automatically based on the key size.

Lugo. * gpg.c (reopen_std): New function to reopen fd 0, 1, or 2 if we are called with them closed. This is to protect our keyring/trustdb files from corruption if they get attached to one of the standard fds. Print a warning if possible that this has happened, and fail completely if we cannot reopen (should never happen). (main): Call it here. * parse-packet.c (dump_sig_subpkt, parse_signature): Fix meaning of key expiration and sig expiration subpackets - zero means "never expire" according to 2440, not "expire instantly". * build-packet.c (build_sig_subpkt_from_sig): Ditto. * getkey.c (fixup_uidnode, merge_selfsigs_main) (merge_selfsigs_subkey): Ditto. * keygen.c (keygen_add_key_expire): Ditto. * getkey.c (get_pubkey_byname) * import.c (import_one): Fix key selection problem when auto-key-locate returns a list of keys, not all of which are usable (revoked, expired, etc). Noted by Simon Josefsson. 2006-05-24 Werner Koch * keyid.c (hash_public_key): Do not double hash the length bytes, they are already included by mpi_print. * misc.c (openpgp_pk_test_algo2): Get test call right. * misc.c (string_to_cipher_algo, string_to_digest_algo): New. * keygen.c (keygen_set_std_prefs): use them here. * gpg.c (main): and here. 2006-05-23 Werner Koch * card-util.c (generate_card_keys): Removed temporary kludge for generate_keypair. * call-agent.c (agent_scd_setattr): Add arg SERIALNO.

(string_count_chr): New. * armor.c (parse_header_line): Use renamed function length_sans_trailing_ws. * options.h, gpg.c: Option --strict is not used thus removed code but kept option. 2006-04-28 David Shaw (wk) * keyserver.c (direct_uri_map): New. (keyserver_spawn): Used here to add "_uri" to certain gpgkeys_xxx helpers when the meaning is different if a path is provided (i.e. ldap). (keyserver_import_cert): Show warning if there is a CERT fingerprint, but no --keyserver set. * keyserver.c: Fix build problem with platforms that stick libcurl in a place not in the regular include search path. * options.h, gpg.c (main): Add --enable-dsa2 and --disable-dsa2. Defaults to disable. * pkclist.c (algo_available): If --enable-dsa2 is set, we're allowed to truncate hashes to fit DSA keys. * sign.c (match_dsa_hash): New. Return the best match hash for a given q size. (do_sign, hash_for, sign_file): When signing with a DSA key, if it has q==160, assume it is an old DSA key and don't allow truncation unless --enable-dsa2 is also set. q!=160 always allows truncation since they must be DSA2 keys. (make_keysig_packet): If the user doesn't specify a --cert-digest-algo, use match_dsa_hash to pick the best hash for key signatures. * gpg.c (print_mds): Add SHA-224. * armor.c (armor_filter, parse_hash_header): Add SHA-224. * sign.c (write_plaintext_packet): Factor common literal packet setup code from here, to... * encode.c (encode_simple): .. there. * main.h, plaintext.c (setup_plaintext_name): Here. New. Make sure the literal packet filename field is UTF-8 encoded. * options.h, gpg.c (main): Make sure --set-filename is UTF-8 encoded and note when filenames are already UTF-8. * keyedit.c (menu_backsign): Give some more verbose errors when we have no need to backsign. * getkey.c (parse_auto_key_locate): Fix dupe-removal code. * keyedit.c (menu_backsign): Allow backsigning even if the secret subkey doesn't have a binding signature. * armor.c (radix64_read): Don't report EOF when reading only a pad (=) character. The EOF actually starts after the pad. * gpg.c (main): Make --export, --send-keys, --recv-keys, --refresh-keys, and --fetch-keys follow their arguments from left to right.

(generate_card_keys): New arg SERIALNO. Do PIN verification here after resetting forced_chv1. 2004-04-26 Werner Koch * card-util.c (change_name): Check that the NAME is not too long. (change_url): Likewise. (change_login): Likewise. 2004-03-23 Werner Koch * g10.c: New options --gpgconf-list, --debug-level and --log-file (set_debug): Add arg DEBUG_LEVEL. (main): Look at less and less version specific config files. From gnupg 1.3. 2004-02-17 Werner Koch * call-agent.c (start_agent): Ignore an empty GPG_AGENT_INFO. * passphrase.c (agent_open): Ditto. 2004-02-12 Werner Koch * gpgv.c: Removed g10defs.h. * Makefile.am: Include cmacros.am for common flags. 2004-02-11 Werner Koch * openfile.c (try_make_homedir): Use GNUPG_DEFAULT_HOMEDIR. * gpgv.c (main): Ditto. * g10.c (main): Ditto. 2004-01-19 Moritz Schulte * keygen.c (do_generate_keypair): Print member fname, instead of newfname, again. (do_generate_keypair): Don't try to execute certain pieces of code in case an error occured. (gen_card_key): Don't print out a message, which is already printed by do_generate_keypair(). 2004-01-18 Moritz Schulte * keygen.c (do_generate_keypair): Print member fname, instead of newfname. 2003-12-17 Werner Koch * card-util.c (print_name): Fixed bad format string usage. (print_isoname): Ditto. * trustdb.c (check_regexp): s/exp/expr/. * keyedit.c (trustsig_prompt): Removed a "> 255" term; it is always false due to the data type. * passphrase.c (agent_get_passphrase): Use xasprintf and avoid non-literal format strings. * tdbio.c (upd_hashtable, drop_from_hashtable, lookup_hashtable): Fixed log_error format string bugs. Kudos to the now working gcc-3.3 -Wformat-nonliteral and Florian Weimer's investigations in gnupg 1.2.3. 2003-12-15 Werner Koch * seckey-cert.c (protect_secret_key): Use gry_create_nonce for the IV; there is not need for real strong random here and it even better protect the random bits used for the key. 2003-11-16 Moritz Schulte * signal.c: Removed unused file. 2003-11-10 Moritz Schulte * Makefile.am (INCLUDES): Added: @LIBGCRYPT_CFLAGS@. 2003-10-25 Werner Koch * call-agent.c (learn_status_cb, scd_genkey_cb): Fixed faulty use of !spacep(). 2003-10-20 Werner Koch * card-util.c (card_edit): New command "passwd". Add logic to check the PIN in advance. (card_status): Add new args to return the serial number. Changed all callers. * call-agent.c (agent_scd_checkpin): New. 2003-10-08 Werner Koch * call-agent.c (agent_scd_getattr): Don't clear the passed info structure, so that it can indeed be updated. * card-util.c (fpr_is_zero): New. (generate_card_keys): New. (card_edit): New command "generate". * keygen.c (generate_keypair): New arg CARD_SERIALNO, removed call to check_smartcard. (check_smartcard,show_smartcard): Removed. (show_sha1_fpr,fpr_is_zero): Removed. 2003-10-01 Werner Koch * card-util.c: Tweaked to use this source also under 1.3. 2003-09-30 Werner Koch * keylist.c (print_card_serialno): New. (list_keyblock_print): Use it here. * card-util.c (toggle_forcesig): New. (card_edit): New command "forcesig". * card-util.c (print_name, print_isoname): Use 0 and not LF fro the max_n arg of tty_print_utf8_string2. * call-agent.c (agent_scd_getattr): New. (learn_status_cb): Release values before assignment so that it can be used by getattr to update the structure. * card-util.c (change_pin): Simplified. We now have only a PIN and an Admin PIN. 2003-09-27 Werner Koch * sign.c (do_sign): Removed disabled testcode. 2003-09-26 Timo Schulz * card_status (card_status): Do not use fputs since the fp parameter can be NULL. This fixes a segv. 2003-09-24 Werner Koch * card-util.c (print_isoname,card_status): Handle opt.with_colons. (print_sha1_fpr_colon): New. 2003-09-23 Werner Koch Merged most of David Shaw's changes in 1.3 since 2003-06-03. * Makefile.am: Include W32LIBS where appropriate. * armor.c (parse_hash_header,armor_filter): Drop TIGER/192 support. * g10.c (print_hex,print_mds): Ditto. * pkclist.c (algo_available): Ditto. * armor.c (armor_filter): Allow using --comment multiple times to get multiple Comment header lines. --no-comments resets list. * options.h, g10.c (main): Ditto. Deprecate --default-comment in favor of --no-comments. * g10.c (main): Trim --help to commonly used options. Remove -f. * g10.c (main): Add --multifile as an alias to turn --encrypt into --encrypt-files (plus --verify-files, --decrypt-files). Error out if --multifile is used with the commands that don't support it yet. * encode.c (use_mdc), g10.c (main): Use RFC1991 and RFC2440 directly to check for MDC usability. Do not set the force_mdc or disable_mdc flags since there is no point any longer. * g10.c (main): Use "keyserver-url" instead of "preferred-keyserver" for the sake of short and simple commands. (add_keyserver_url): Clarify a few strings. It's a "preferred keyserver URL". * keyedit.c (keyedit_menu): Ditto. * sign.c (mk_notation_policy_etc): Ditto. * main.h, keygen.c (keygen_add_keyserver_url): Signature callback for adding a keyserver URL. * keyedit.c (keyedit_menu, menu_set_keyserver_url): New command to set preferred keyserver to specified (or all) user IDs. * build-packet.c (build_sig_subpkt): Set preferred keyserver flag while building a preferred keyserver subpacket. * keylist.c (show_policy_url, show_keyserver_url): URLs might be UTF8. * keyedit.c (menu_addrevoker): Fix leaking a few bytes. * keyedit.c (show_key_with_all_names): Use list-option show-long-keyid in main --edit-key display. * keyedit.c (print_and_check_one_sig): Use list-option show-long-keyid in --edit-key "check" function. * passphrase.c (agent_send_all_options): Make use of $GPG_TTY. * g10.c (main): Disable use-agent if passphrase-fd is given later. Suggested by Kurt Garloff. * exec.c, g10.c, gpgv.c, passphrase.c, photoid.c: s/__MINGW32__/_WIN32/ to help building on native Windows compilers. Requested by Brian Gladman. From Werner on stable branch. * options.h, g10.c (main): Add list-option list-preferred-keyserver. * keyedit.c (change_passphrase): When responding 'no' to the blank passphrase question, re-prompt for a new passphrase. This is bug #202. * mainproc.c (check_sig_and_print): Use two different preferred keyserver displays - one if the key is not present (to tell the user where to get the key), the other if it is present (to tell the user where the key can be refreshed). * packet.h, parse-packet.c (parse_signature): Set flag if a preferred keyserver is present. * keylist.c (list_keyblock_print): Show keyserver url in listings with list-option show-keyserver-url. * mainproc.c (check_sig_and_print): Get the uid validity before printing any sig results to avoid munging the output with trustdb warnings. * g10.c (main): Don't include --show-keyring in --help as it is deprecated. * options.skel: Note that keyserver.pgp.com isn't synchronized, and explain the roundrobin a bit better. * sig-check.c (check_key_signature2), import.c (import_one, import_revoke_cert, chk_self_sigs, delete_inv_parts, collapse_uids, merge_blocks): Make much quieter during import of slightly munged, but recoverable, keys. Use log_error for unrecoverable import failures. * keyring.c (keyring_rebuild_cache): Comment. * sign.c (mk_notation_and_policy): Making a v3 signature with notations or policy urls is an error, not an info (i.e. increment the errorcount). Don't print the notation or policy url to stdout since it can be mixed into the output stream when piping and munge the stream. * packet.h, sig-check.c (signature_check2, do_check, do_check_messages): Provide a signing-key-is-revoked flag. Change all callers. * status.h, status.c (get_status_string): New REVKEYSIG status tag for a good signature from a revoked key. * mainproc.c (do_check_sig, check_sig_and_print): Use it here. * import.c (import_revoke_cert, merge_blocks, merge_sigs): Compare actual signatures on import rather than using keyid or class matching. This does not change actual behavior with a key, but does mean that all sigs are imported whether they will be used or not. * parse-packet.c (parse_signature): Don't give "signature packet without xxxx" warnings for experimental pk algorithms. An experimental algorithm may not have a notion of (for example) a keyid (i.e. PGP's x.509 stuff). * options.h, g10.c (main), keylist.c (list_keyblock_print), keyedit.c (print_and_check_one_sig): New "show-sig-expire" list-option to show signature expiration dates (if any). * options.h, g10.c (main, add_keyserver_url): Add --sig-preferred-keyserver to implant a "where to get my key" subpacket into a signature. * sign.c (mk_notation_and_policy): Rename to mk_notation_policy_etc and add preferred keyserver support for signatures. * keygen.c (do_add_key_flags): Don't set the certify flag for subkeys. (ask_algo): Provide key flags for DSA, Elgamal_e, and Elgamal subkeys. (generate_keypair): Provide key flags for the default DSA/Elgamal keys. * sig-check.c (signature_check, signature_check2, check_key_signature, check_key_signature2): Allow passing NULLs for unused parameters in the x2 form of each function to avoid the need for dummy variables. getkey.c, mainproc.c: Change all callers. * trustdb.h, trustdb.c (read_trust_options): New. Returns items from the trustdb version record. * keylist.c (public_key_list): Use it here for the new "tru" record. * gpgv.c (read_trust_options): Stub. * keyedit.c (show_key_with_all_names): Use list-option show-validity in --edit-key interface as well. * options.h, g10.c (main), mainproc.c (check_sig_and_print): Add verify-options "show-validity" and "show-long-keyid" to show trustdb validity and long keyids during (file) signature verification. * packet.h, main.h, sig-check.c (signature_check2) (check_key_signature2, do_check): If ret_pk is set, fill in the pk used to verify the signature. Change all callers in getkey.c, mainproc.c, and sig-check.c. * keylist.c (list_keyblock_colon): Use the ret_pk from above to put the fingerprint of the signing key in "sig" records during a --with-colons --check-sigs. This requires --no-sig-cache as well since we don't cache fingerprints. * parse-packet.c (parse_signature): No need to reserve 8 bytes for the unhashed signature cache any longer. * misc.c (pct_expando): Add two new expandos - signer's fingerprint (%g), and signer's primary fingerprint (%p). * g10.c (main): Add --rfc2440 alias for --openpgp since in a few months, they won't be the same thing. * keyserver.c (parse_keyserver_uri): Accept "http" as an alias for "hkp", since it is occasionally written that way. (keyserver_spawn): Use ascii_isspace to avoid locale issues. * keygen.c (ask_user_id): Make --allow-freeform-uid apply to the email field as well as the name field, and allow mixing fields when it is set. * trustdb.c (validate_one_keyblock): Certifications on revoked or expired uids do not count in the web of trust. * signal.c (init_one_signal, pause_on_sigusr, do_block): Only use sigprocmask() if we have sigset_t, and only use sigaction() if we have struct sigaction. This is for Forte c89 on Solaris which seems to define only the function call half of the two pairs by default. (pause_on_sigusr): Typo. (do_block): If we can't use sigprocmask() and sigset_t, try to get the number of signals from NSIG as well as MAXSIG, and if we can't, fail with an explanation. * signal.c, tdbio.c: Comment out the transaction code. It was not used in this version, and was causing some build problems on quasi-posix platforms (Solaris and Forte c89). * keylist.c (list_keyblock_colon): Don't include validity values when listing secret keys since they can be incorrect and/or misleading. This is a temporary kludge, and will be handled properly in 1.9/2.0. * mainproc.c (check_sig_and_print): Only show the "key available from" preferred keyserver line if the key is not currently present. * keyedit.c (sign_uids): Do not sign expired uids without --expert (same behavior as revoked uids). Do not allow signing a user ID without a self-signature. --expert overrides. Add additional prompt to the signature level question. (menu_expire): When changing expiration dates, don't replace selfsigs on revoked uids since this would effectively unrevoke them. There is also no point in replacing expired selfsigs. This is bug #181 * g10.c (add_notation_data): Make sure that only ascii is passed to iscntrl. Noted by Christian Biere. * getkey.c (classify_user_id2): Replaced isspace by spacep * keygen.c (ask_user_id): Ditto. (get_parameter_algo): Ditto. * keyedit.c (keyedit_menu): Ditto. * tdbdump.c (import_ownertrust): Ditto. s/isxdigit/hexdigitp/. * revoke.c (ask_revocation_reason): * keyserver.c (keyserver_spawn): Dito. * parse-packet.c (parse): Disallow old style partial length for all key material packets to avoid possible corruption of keyrings. * import.c (import_keys_internal): Invalidate the cache so that the file descriptor gets closed. Fixes bug reported by Juan F. Codagnone. * options.h, g10.c (main), main.h, keylist.c (show_keyserver_url), mainproc.c (check_sig_and_print), parse-packet.c (dump_sig_subpkt, parse_one_sig_subpkt, can_handle_critical): Add read-only support for preferred keyserver subpackets. They're basically policy URLs with a different name. Add a verify-option "show-preferred-keyserver" to turn them on and off (on by default, as per stable branch). * g10.c (main): Add "--set-notation" as alias to "--notation-data" this is to make things consistent with --set-policy-url meaning both sigs and certs. * options.h, g10.c (main), keylist.c (list_keyblock_print): Add "show-validity" and "show-long-keyid" list-options. * gpgv.c (get_validity, trust_value_to_string): Stubs. * g10.c (main): Use SAFE_VERSION instead of VERSION in the version-specific gpg.conf file so it can be overridden on RISCOS. * keyedit.c (show_key_with_all_names): Fix assertion failure when using toggle to see a secret key. Reported by Maxim Britov. 2003-09-22 Timo Schulz * card-util.c (card_status): Free pk in case of an error and return if the card is no OpenPGP card. 2003-09-18 Werner Koch * g10.c: New command --card-edit. * card-util.c (card_status): Use tty_fprintf for all output. (print_sha1_fpr, print_isoname): Ditto. (get_one_name,change_name, change_url, change_login,change_lang) (change_sex): New; taken from keygen.c. * keygen.c (smartcard_get_one_name, smartcard_change_name) (smartcard_change_url, smartcard_change_login_data) (smartcard_change_lang, smartcard_change_sex): Removed. (check_smartcard): Removed most menu items. 2003-09-06 Werner Koch * misc.c (openpgp_pk_algo_usage): Allow AUTH where SIGN is allowed. * keygen.c (ask_passphrase): No need to allocated S2K in secure memory. 2003-09-04 Werner Koch * keygen.c (do_add_key_flags, parse_parameter_usage) (do_generate_keypair): Add support the proposed AUTH key flag. * getkey.c (fixup_uidnode, merge_selfsigs_main) (merge_selfsigs_subkey, premerge_public_with_secret): Ditto. * keylist.c (print_capabilities): Ditto. 2003-08-25 Timo Schulz * pkglue.c (mpi_from_sexp): New. Used to factor out some common code. 2003-08-24 Werner Koch * keygen.c (do_generate_keypair): Print a reminder to use --gen-revoke. 2003-08-18 Timo Schulz * encode.c (encode_sesskey): Checked the code and removed the warning since all compatibility checks with PGP succeeded. * mainproc.c (symkey_decrypt_sesskey): Better check for the algorithm and check the return values of some functions. * mdc.c (use_mdc): Simplified. 2003-08-07 Werner Koch * pkglue.c (pk_sign): Fix last change. (pk_verify): Check for valid DATA array so that we don't segv in Libgcrypt. (pk_verify): Ditto. 2003-08-06 Werner Koch * pkglue.c (pk_sign): Allow signing using RSA. 2003-08-05 Werner Koch * Makefile.am (install-data-local): Dropped check for the ancient gpgm tool. (bin_PROGRAMS): Renamed gpg to gpg2 and gpgv to gpgv2. This is so that it won't conflict with the current stable version of gpg. * pkglue.c (pk_check_secret_key): New. * seckey-cert.c (do_check): Reenable this test here again. * g10.c (main): Add command -K as an alias for --list-secret-keys. Command "-k" is now an alias to --list-keys. Remove special treatment of -kv and -kvv. (set_cmd): Ditto. (main): Strip a "-cvs" suffix when testing for a version specific config file. * status.h, status.c, g10.c [USE_SHM_COPROCESSING]: Removed. This is not any longer available. 2003-07-29 Werner Koch * g10.c (main): Add secmem features and set the random seed file. (g10_exit): Update the random seed file. * parse-packet.c (parse_signature,read_protected_v3_mpi) (parse_key): Fixed use of mpi_set_opaque. * keygen.c (gen_card_key): Ditto. 2003-07-28 Werner Koch * status.c (progress_cb): Adjusted for use with Libcgrypt. (set_status_fd): Register that callback. * keygen.c (smartcard_change_login_data): New. (smartcard_change_lang): New. (smartcard_change_sex): New.

(genhelp_protect, genhelp_factors, key_from_sexp): New. * comment.c (make_comment_node_from_buffer): New. (make_comment_node): Reimplemented in terms of above. 2003-07-27 Werner Koch Adjusted for gcry_mpi_print and gcry_mpi_scan API change. 2003-07-24 Werner Koch * g10.c: New command --card-status. * card-util.c (card_status): New. * call-agent.c (learn_status_cb): Parse more information. * keylist.c (print_pubkey_info): Add FP arg for optional printing to a stream. Changed all callers. 2003-07-23 Werner Koch * keygen.c (generate_keypair): Create an AUTHKEYTYPE entry for cards. (do_generate_keypair): Abd generate the authkey.

(export_seckeys,export_secsubkeys): Check sexp-format option. (do_export): Ignore armor for sexp format. (do_export_stream): Handle sexp-format. (write_sexp_line,write_sexp_keyparm, build_sexp_seckey): New.

(smartcard_change_url): Nw. 2003-07-02 Werner Koch * seckey-cert.c (is_secret_key_protected): Let it handle mode 1002. 2003-07-01 Werner Koch * keygen.c (gen_card_key): Obviously we should use the creation date received from SCDAEMON, so that the fingerprints will match. * sign.c (do_sign): Pass the serialno to the sign code. * keyid.c (serialno_and_fpr_from_sk): New. 2003-06-30 Werner Koch * call-agent.h (agent_card_info_s): Add field serialno. * call-agent.c (store_serialno): New. (learn_status_cb): Store the serial number. * keygen.c (gen_card_key): Store the serial number (check_smartcard): New argument to return the serial number.

(main): Use gnupg_init_signals and register malloc for assuan. 2003-06-23 Werner Koch * keyid.c (do_fingerprint_md): Made it work again. 2003-06-19 Werner Koch Fixed all "==" comparisons against error code constants to use gpg_err_code(). * import.c (import_secret_one): (import_revoke_cert): (chk_self_sigs): * misc.c (openpgp_md_map_name): Check also for the Hx format. (openpgp_cipher_map_name): Check also for the Sx format. (pubkey_get_npkey): Adjusted for changed gcrypt API. (pubkey_get_nskey): Ditto. (pubkey_get_nsig): Ditto. (pubkey_get_nenc): Ditto. 2003-06-18 Werner Koch Finished the bulk of changes for gnupg 1.9. This included switching to libgcrypt functions, using shared error codes from libgpg-error, replacing the old functions we used to have in ../util by those in ../jnlib and ../common, renaming the malloc functions and a couple of types. Note, that not all changes are listed below becuause they are too similar and done at far too many places. As of today the code builds using the current libgcrypt from CVS but it is very unlikely that it actually works. * sig-check.c (cmp_help): Removed. Was never used. * pkglue.c: New. Most stuff taken from gnupg 1.1.2. * pkglue.h: New. * misc.c (pull_in_libs): Removed. * keygen.c (count_chr): New. (ask_user_id): Removed faked RNG support. * misc.c (openpgp_md_map_name,openpgp_cipher_map_name) (openpgp_pk_map_name): New. * skclist.c (build_sk_list): Removed faked RNG support. (is_insecure): Removed. * comment.c (make_mpi_comment_node): Use gcry MPI print function. * keyid.c (v3_keyid): New. * misc.c (mpi_write,mpi_write_opaque,mpi_read,mpi_read_opaque) (mpi_print): New. Taken from gnupg 1.1.2. (checksum_mpi): Replaced by implementation from 1.1.2. * g10.c (my_strusage): Renamed from strusage and return NULL instead calling a default function. (add_to_strlist2): New. Taken from ../util/strgutil.c of gnupg 1.2. * plaintext.c (handle_plaintext): New arg CREATE_FILE to cope with the fact that gpg-error does not have this error code anymore. * mainproc.c (symkey_decrypt_sesskey): Ditto. * seskey.c (make_session_key): Adjusted for use with libgcrypt. (encode_session_key): Ditto. (do_encode_md): Ditto. (encode_md_value): Ditto. * keyring.c: Use libgpg-error instead of READ_ERROR etc. * g10.c: Adjusted all algorithm name/id mapping functions. (set_debug): Pass MPI and CRYPTO debug values to libgcrypt. * Makefile.am (INCLUDES): Define LOCALEDIR and the default error source. * g10.c (i18n_init): s/G10_LOCALEDIR/LOCALEDIR/. Renamed m_alloc et al to xmalloc et al. s/g10_errstr/gpg_strerror/ s/MPI/gcry_mpi_t/ Adjusted all md_open calls to the libgcrypt API. * build-packet.c (do_comment): Return error code from iobuf write function. (do_user_id): Ditto. (do_public_key): Ditto. * Makefile.am: Add new files, link gpg with libgpg-error. * g10.c, options.h: New option --agent-program. * call-agent.c: New. * gpg.h, call-agent.h: New. 2003-06-03 David Shaw * options.h, g10.c (main), keylist.c (list_keyblock_print): Add "show-validity" and "show-long-keyid" list-options. * gpgv.c (get_validity, trust_value_to_string): Stubs. * g10.c (main): Use SAFE_VERSION instead of VERSION in the version-specific gpg.conf file so it can be overridden on RISCOS. 2003-06-01 David Shaw * g10.c (main), keylist.c (show_policy_url, show_notation), mainproc.c (check_sig_and_print): Emulate the old policy and notation behavior (display by default). Send to status-fd whether it is displayed on the screen or not. * g10.c (main): Since we now have some options in devel that won't work in a stable branch gpg.conf file, try for a version-specific gpg.conf-VERSION file before falling back to gpg.conf. * main.h, options.h: Move various option flags to options.h. 2003-05-31 David Shaw * mainproc.c (check_sig_and_print), main.h, keylist.c (show_policy, show_notation): Collapse the old print_notation_data into show_policy() and show_notation() so there is only one function to print notations and policy URLs. * options.h, main.h, g10.c (main), keyedit.c (print_and_check_one_sig), keylist.c (list_one, list_keyblock_print), pkclist.c (do_edit_ownertrust), sign.c (mk_notation_and_policy): New "list-options" and "verify-options" commands. These replace the existing --show-photos/--no-show-photos, --show-notation/--no-show-notation, --show-policy-url/--no-show-policy-url, and --show-keyring options. The new method is more flexible since a user can specify (for example) showing photos during sig verification, but not in key listings. The old options are emulated. * main.h, misc.c (parse_options): New general option line parser. Fix the bug in the old version that did not handle report syntax errors after a valid entry. * import.c (parse_import_options), export.c (parse_export_options): Call it here instead of duplicating the code. 2003-05-30 David Shaw * keylist.c (list_one): Don't show the keyring filename when in --with-colons mode. Actually translate "Keyring" string. * mainproc.c (proc_tree): We can't currently handle multiple signatures of different classes or digests (we'd pretty much have to run a different hash context for each), but if they are all the same, make an exception. This is Debian bug #194292. * sig-check.c (check_key_signature2): Make string translatable. * packet.h, getkey.c (fixup_uidnode): Mark real primary uids differently than assumed primaries. * keyedit.c (no_primary_warning): Use the differently marked primaries here in a new function to warn when an --edit-key command might rearrange the self-sig dates enough to change which uid is primary. (menu_expire, menu_set_preferences): Use no_primary_warning() here. * Makefile.am: Use @DLLIBS@ for -ldl. 2003-05-26 David Shaw * getkey.c (premerge_public_with_secret): Made "no secret subkey for" warning a verbose item and translatable. (From wk on stable branch) * sig-check.c (check_key_signature2): Made "no subkey for subkey binding packet" a verbose item instead of a !quiet one. There are too many garbled keys out in the wild. (From wk on stable branch) * filter.h: Remove const from WHAT. (From wk on stable branch) * progress.c (handle_progress): Store a copy of NAME. (progress_filter): Release WHAT, make sure not to print a NULL WHAT. (From wk on stable branch) * openfile.c (open_sigfile): Adjust free for new progress semantics. (From wk on stable branch) * plaintext.c (ask_for_detached_datafile): Don't dealloc pfx->WHAT. (From wk on stable branch) * seckey-cert.c (do_check): Issue the RSA_OR_IDEA status when the cipher algo is IDEA to make it easier to track down the problem. (From twoaday on stable branch) 2003-05-24 David Shaw * armor.c, g10.c, kbnode.c, misc.c, pkclist.c, sign.c, build-packet.c, getkey.c, keydb.c, openfile.c, plaintext.c, status.c, gpgv.c, keygen.c, options.h, sig-check.c, tdbio.h, encode.c, mainproc.c, parse-packet.c, signal.c, textfilter.c: Edit all preprocessor instructions to remove whitespace before the '#'. This is not required by C89, but there are some compilers out there that don't like it. 2003-05-21 David Shaw * trustdb.h, trustdb.c (is_disabled), gpgv.c (is_disabled): Rename is_disabled to cache_disabled_value, which now takes a pk and not just the keyid. This is for speed since there is no need to re-fetch a key when we already have that key handy. Cache the result of the check so we don't need to hit the trustdb more than once. * getkey.c (skip_disabled): New function to get a pk and call is_disabled on it. (key_byname): Use it here. * packet.h, getkey.c (skip_disabled), keylist.c (print_capabilities): New "pk_is_disabled" macro to retrieve the cached disabled value if available, and fill it in via cache_disabled_value if not available. * trustdb.c (get_validity): Cache the disabled value since we have it handy and it might be useful later. * parse-packet.c (parse_key): Clear disabled flag when parsing a new key. Just in case someone forgets to clear the whole key. * getkey.c (merge_selfsigs_main): Add an "if all else fails" path for setting a single user ID primary when there are multiple set primaries all at the same second, or no primaries set and the most recent user IDs are at the same second, or no signed user IDs at all. This is arbitrary, but deterministic. * exec.h, photoid.h: Add copyright message. * keylist.c (list_keyblock_print): Don't dump attribs for revoked/expired/etc uids for non-colon key listings. This is for consistency with --show-photos. * main.h, keylist.c (dump_attribs), mainproc.c (check_sig_and_print): Dump attribs if --attrib-fd is set when verifying signatures. * g10.c (main): New --gnupg option to disable the various --openpgp, --pgpX, etc. options. This is the same as --no-XXXX for those options. * revoke.c (ask_revocation_reason): Clear old reason if user elects to repeat question. This is bug 153. * keyedit.c (sign_uids): Show keyid of the key making the signature. 2003-05-21 Werner Koch * progress.c (handle_progress) * sign.c (write_plaintext_packet) * encode.c (encode_simple,encode_crypt): Make sure that a filename of "-" is considered to be stdin so that iobuf_get_filelength won't get called. This fixes bug 156 reported by Gregery Barton. 2003-05-02 David Shaw * packet.h, build-packet.c (build_sig_subpkt), export.c (do_export_stream), import.c (remove_bad_stuff, import), parse-packet.c (dump_sig_subpkt, parse_one_sig_subpkt): Remove vestigal code for the old sig cache subpacket. This wasn't completely harmless as it caused subpacket 101 to disappear on import and export. * options.h, armor.c, cipher.c, g10.c, keyedit.c, pkclist.c, sign.c, encode.c, getkey.c, revoke.c: The current flags for different levels of PGP-ness are massively complex. This is step one in simplifying them. No functional change yet, just use a macro to check for compliance level. * sign.c (sign_file): Fix bug that causes spurious compression preference warning. * sign.c (clearsign_file): Fix bug that prevents proper warning message from appearing when clearsigning in --pgp2 mode with a non-v3 RSA key. * main.h, misc.c (compliance_option_string, compliance_string, compliance_failure), pkclist.c (build_pk_list), sign.c (sign_file, clearsign_file), encode.c (encode_crypt, write_pubkey_enc_from_list): New functions to put the "this message may not be usable...." warning in one place. * options.h, g10.c (main): Part two of the simplification. Use a single enum to indicate what we are compliant to (1991, 2440, PGPx, etc.) * g10.c (main): Show errors for failure in export, send-keys, recv-keys, and refresh-keys. * options.h, g10.c (main): Give algorithm warnings for algorithms chosen against the --pgpX and --openpgp rules. * keydb.h, pkclist.c (algo_available): Make TIGER192 invalid in --openpgp mode. * sign.c (sign_file), pkclist.c (algo_available): Allow passing a hint of 0. 2003-05-01 David Shaw * tdbio.c (create_version_record): Only create new trustdbs with TM_CLASSIC or TM_PGP. * trustdb.h, trustdb.c (trust_string, get_ownertrust_string, get_validity_string, ask_ownertrust, validate_keys), pkclist.c (do_edit_ownertrust): Rename trust_string to trust_value_to_string for naming consistency. * trustdb.h, trustdb.c (string_to_trust_value): New function to translate a string to a trust value. * g10.c (main): Use string_to_trust_value here for --force-ownertrust. * options.h, g10.c (main), trustdb.c (trust_model_string, init_trustdb, check_trustdb, update_trustdb, get_validity, validate_one_keyblock): An "OpenPGP" trust model is misleading since there is no official OpenPGP trust model. Use "PGP" instead. 2003-04-30 David Shaw * build-packet.c (build_sig_subpkt): Comments. * exec.c (exec_write): Cast NULL to void* to properly terminate varargs list. * keyedit.c (show_key_with_all_names): Just for safety, catch an invalid pk algorithm. * sign.c (make_keysig_packet): Crucial that the call to mksubpkt comes LAST before the calls to finalize the sig as that makes it possible for the mksubpkt function to get a reliable pointer to the subpacket area. * pkclist.c (do_we_trust_pre): If an untrusted key was chosen by a particular user ID, use that ID as the one to ask about when prompting whether to use the key anyway. (build_pk_list): Similar change here when adding keys to the recipient list. * trustdb.c (update_validity): Fix bug that prevented more than one validity record per trust record. (get_validity): When retrieving validity for a (user) supplied user ID, return the validity for that user ID only, and do not fall back to the general key validity. (validate_one_keyblock): Some commentary on whether non-self-signed user IDs belong in the web of trust (arguably, they do). 2003-04-27 David Shaw * g10.c (main): Add --no-textmode. * export.c (do_export_stream), keyedit.c (show_key_with_all_names, menu_addrevoker), mainproc.c (check_sig_and_print), photoid.c (show_photos), sign.c (mk_notation_and_policy), trustdb.c (get_validity, reset_trust_records, validate_keys): Make some strings translatable. * mainproc.c (check_sig_and_print): Show digest algorithm and sig class when verifying a sig with --verbose on, and add version, pk and hash algorithms and sig class to VALIDSIG. * parse-packet.c (enum_sig_subpkt): Make a warning message a --verbose warning message since we don't need to warn every time we see an unknown critical (we only need to invalidate the signature). * trustdb.c (init_trustdb): Check the trustdb options even with TM_AUTO since the auto may become TM_CLASSIC or TM_OPENPGP. 2003-04-26 David Shaw * sign.c (do_sign): Show the hash used when making a signature in verbose mode. * tdbio.h, tdbio.c (tdbio_read_model): New function to return the trust model used in a given trustdb. * options.h, g10.c (main), trustdb.c (init_trustdb, check_trustdb, update_trustdb): Use tdbio_read_model to implement an "auto" trust model which is set via the trustdb. 2003-04-23 David Shaw * import.c (import_revoke_cert): Remove ultimate trust when revoking an ultimately trusted key. * keyedit.c (sign_uids): Allow replacing expired signatures. Allow duplicate signatures with --expert. * pkclist.c (check_signatures_trust): Don't display a null fingerprint when checking a signature with --always-trust enabled. * filter.h (progress_filter_context_t), progress.c (handle_progress), plaintext.c (ask_for_detached_datafile, hash_datafiles): Fix compiler warnings. Make "what" constant. * build-packet.c (do_plaintext): Do not create invalid literal packets with >255-byte names. 2003-04-15 Werner Koch * Makefile.am (AM_CFLAGS): Make use of AM_CFLAGS and AM_LDFLAGS. * g10.c, options.h: New option --enable-progress-filter. * progress.c (handle_progress): Make use of it. 2003-04-15 Marcus Brinkmann * progress.c: New file. * Makefile.am (common_source): Add progress.c. * filter.h (progress_filter_context_t): New type. (progress_filter, handle_progress): New prototypes. * main.h (open_sigfile): New argument for prototype. * openfile.c (open_sigfile): New argument to install progress filter. * encode.c (encode_simple): New variable PFX. Register progress filter. Install text_filter after that. (encode_crypt): Likewise. * sign.c (sign_file): Likewise. (clearsign_file): Likewise. * decrypt.c (decrypt_message): Likewise. (decrypt_messages): Likewise. * verify.c (verify_signatures): Likewise. (verify_one_file): Likewise. * plaintext.c (hash_datafiles): Likewise. (ask_for_detached_datafile): Likewise. 2003-04-10 Werner Koch * passphrase.c (read_passphrase_from_fd): Do a dummy read if the agent is to be used. Noted by Ingo Klöcker. (agent_get_passphrase): Inhibit caching when we have no fingerprint. This is required for key generation as well as for symmetric only encryption. * passphrase .c (agent_get_passphrase): New arg CANCELED. (passphrase_to_dek): Ditto. Passed to above. Changed all callers to pass NULL. * seckey-cert.c (do_check): New arg CANCELED. (check_secret_key): Terminate loop when canceled. * keyedit.c (change_passphrase): Pass ERRTEXT untranslated to passphrase_to_dek and translate where appropriate. * seckey-cert.c (check_secret_key): Ditto. * keygen.c (ask_passphrase): Ditto. * passphrase.c (agent_get_passphrase): Translate the TRYAGAIN_TEXT. Switch the codeset to utf-8. 2003-04-09 Werner Koch * decrypt.c (decrypt_messages): Fixed error handling; the function used to re-loop with same file after an error. Reported by Joseph Walton. 2003-04-08 David Shaw * main.h, g10.c (main), import.c (parse_import_options, fix_pks_corruption): It's really PKS corruption, not HKP corruption. Keep the old repair-hkp-subkey-bug command as an alias. * g10.c (main): Rename --no-version to --no-emit-version for consistency. Keep --no-version as an alias. 2003-04-04 David Shaw * pkclist.c (algo_available): PGP 8 can use the SHA-256 hash. * sign.c (sign_file, clearsign_file, sign_symencrypt_file): Remove unused code. 2003-04-01 Werner Koch * mainproc.c (check_sig_and_print): Add primary key fpr to VALIDSIG status. 2003-03-24 David Shaw * keydb.h: Err on the side of making an unknown signature a SIG rather than a CERT. * import.c (delete_inv_parts): Discard any key signatures that aren't key types (i.e. 0x00, 0x01, etc.) * g10.c (main): Add deprecated option warning for --list-ownertrust. Add --compression-algo alias for --compress-algo. Change --version output strings to match "showpref" strings, and make translatable. * status.c (do_get_from_fd): Accept 'y' as well as 'Y' for --command-fd boolean input. * trustdb.c: Fix typo (DISABLE_REGEXP -> DISABLE_REGEX) * keyedit.c (show_key_with_all_names_colon): Show no-ks-modify flag. 2003-03-11 David Shaw * options.h, g10.c (main), keyserver.c (kopts): Add "try-dns-srv" keyserver option. Defaults to on. * passphrase.c (agent_get_passphrase): Fix memory leak with symmetric messages. Fix segfault with symmetric messages. Fix incorrect prompt with symmetric messages. 2003-03-10 Werner Koch * compress.c (init_uncompress): Use a 15 bit window size so that the output of implementations which don't run for PGP 2 compatibility won't get garbled. 2003-03-04 David Shaw * trustdb.c (validate_keys): Mask the ownertrust when building the list of fully valid keys so that disabled keys are still counted in the web of trust. (get_ownertrust_with_min): Do the same for the minimum ownertrust calculation. * parse-packet.c (dump_sig_subpkt): Show the notation names for not-human-readable notations. Fix cosmetic off-by-one length counter. * options.skel: Add explantion and commented-out "no-mangle-dos-filenames". * mainproc.c (proc_encrypted): Make string translatable. * keyserver.c (keyserver_spawn): Quote ':', '%', and any 8-bit characters in the uid strings sent to the keyserver helper. * keyring.c (keyring_rebuild_cache): Lock the keyring while rebuilding the signature caches to prevent another gpg from tampering with the temporary copy. * keygen.c (keygen_set_std_prefs): Include AES192 and AES256 in default prefs. * keyedit.c (show_prefs): Make strings translatable. * keydb.c: Double the maximum number of keyrings to 40. * gpgv.c (main): Fix bug #113 - gpgv should accept the --ignore-time-conflict option. * g10.c (main): --openpgp disables --pgpX. Double the amount of secure memory to 32k (keys are getting bigger these days). * Makefile.am: Makefile.am: Use @CAPLIBS@ to link in -lcap if we are using capabilities. 2003-02-26 David Shaw * keyserver.c (keyserver_spawn): Include various pieces of information about the key in the data sent to the keyserver helper. This allows the helper to use it in instructing a remote server which may not have any actual OpenPGP smarts in parsing keys. * main.h, export.c (export_pubkeys_stream, do_export_stream): Add ability to return only the first match in an exported keyblock for keyserver usage. This should be replaced at some point with a more flexible solution where each key can be armored seperately. 2003-02-22 David Shaw * sign.c (sign_file): Do not push textmode filter onto an unopened IOBUF (segfault). Noted by Marcus Brinkmann. Push and reinitialize textmode filter for each file in a multiple file list. * packet.h, getkey.c (fixup_uidnode), keyedit.c (show_prefs): Set and show the keyserver no-modify flag. * keygen.c (add_keyserver_modify): New. (keygen_upd_std_prefs): Call it here. (keygen_set_std_prefs): Accept "ks-modify" and "no-ks-modify" as prefs to set and unset keyserver modify flag. * g10.c (main): Accept "s1" in addition to "idea" to match the other ciphers. * main.h, misc.c (idea_cipher_warn): We don't need this if IDEA has been disabled. 2003-02-21 David Shaw * keygen.c (keygen_set_std_prefs): Don't put AES or CAST5 in default prefs if they are disabled. * g10.c (main): Use 3DES instead of CAST5 if we don't have CAST5 support. Use 3DES for the s2k cipher in --openpgp mode. (print_mds): #ifdef all of the optional digest algorithms. 2003-02-12 David Shaw * keydb.h, getkey.c (classify_user_id, classify_user_id2): Make 'exact' a per-desc item. Merge into one function since 'force_exact' is no longer needed. (key_byname): Use new classify_user_id function, and new exact flag in KEYDB_SEARCH_DESC. * keyring.h, keyring.c (keyring_search): Return an optional index to show which KEYDB_SEARCH_DESC was the matching one. * keydb.h, keydb.c (keydb_search): Rename to keydb_search2, and pass the optional index to keyring_search. Add a macro version of keydb_search that calls this new function. * export.c (do_export_stream): If the keyid! syntax is used, export only that specified key. If the key in question is a subkey, export the primary plus that subkey only. 2003-02-11 David Shaw * exec.c (set_exec_path): Add debugging line. * g10.c (print_hex, print_mds): Print long hash strings a lot neater. This assumes at least an 80-character display, as there are a few other similar assumptions here and there. Users who need unformatted hashes can still use with-colons. Check that SHA384 and 512 are available before using them as they are no longer always available. * Makefile.am: Use a local copy of libexecdir along with @PACKAGE@ as GNUPG_LIBEXECDIR so it can be easily overridden at make time. 2003-02-04 David Shaw * armor.c (parse_hash_header, armor_filter): Accept the new SHAs in the armor Hash: header. * g10.c (print_hex): Print long hash strings a little neater. (print_mds): Add the new SHAs to the hash list. 2003-02-02 David Shaw * keyedit.c (menu_revuid): Properly handle a nonselfsigned uid on a v4 key (treat as a v4 revocation). * import.c (print_import_check): Do not re-utf8 convert user IDs. 2003-01-27 David Shaw * mainproc.c (list_node): Show signature expiration date in with-colons sig records. * keylist.c (list_keyblock_colon), mainproc.c (list_node): Show trust sig information in with-colons sig records. 2003-01-16 David Shaw * g10.c (add_group): Trim whitespace after a group name so it does not matter where the user puts the = sign. * options.skel: Comment out the first three lines in case someone manually copies the skel file to their homedir. * sign.c (clearsign_file): Only use pgp2mode with v3 keys and MD5. This matches what we do when decoding such messages and prevents creating a message (v3+RIPEMD/160) that we can't verify. * sig-check.c (signature_check2): Use G10ERR_GENERAL as the error for signature digest conflict. BAD_SIGN implies that a signature was checked and we may try and print out a user ID for a key that doesn't exist. 2003-01-15 David Shaw * trustdb.c (init_trustdb, get_validity): Don't use a changed trust model to indicate a dirty trustdb, and never auto-rebuild a dirty trustdb with the "always" trust model. * g10.c (add_group): Last commit missed the \t ;) 2003-01-14 David Shaw * packet.h, parse-packet.c (setup_user_id), free-packet.c (free_user_id), keydb.h, keyid.c (namehash_from_uid): New function to rmd160-hash the contents of a user ID packet and cache it in the uid object. * keylist.c (list_keyblock_colon): Use namehash in field 8 of uids. Show dates for creation (selfsig date), and expiration in fields 6 and 7. * trustdb.c (get_validity, get_validity_counts, update_validity): Use new namehash function rather than hashing it locally. 2003-01-14 Werner Koch * g10.c (add_group): Fixed group parsing to allow more than one delimiter in a row and also allow tab as delimiter. 2003-01-12 David Shaw * tdbio.c (tdbio_set_dbname): Fix assertion failure with non-fully-qualified trustdb names. 2003-01-11 David Shaw * trustdb.c (get_validity_info, get_ownertrust_info, trust_letter): Simplify by returning a ? for error directly. * keyedit.c (show_key_with_all_names): Use get_validity_string and get_ownertrust_string to show full word versions of trust (i.e. "full" instead of 'f'). * trustdb.h, trustdb.c (get_ownertrust_string, get_validity_string): Same as get_ownertrust_info, and get_validity_info, except returns a full string. * trustdb.c (get_ownertrust_with_min): New. Same as 'get_ownertrust' but takes the min_ownertrust value into account. 2003-01-10 David Shaw * armor.c (armor_filter): Comment about PGP's end of line tab problem. * trustdb.h, trustdb.c (trust_letter): Make static. (get_ownertrust_info, get_validity_info): Don't mask the trust level twice. * trustdb.h, gpgv.c, trustdb.c (get_validity, get_validity_info), keylist.c (list_keyblock_colon), keyedit.c (show_key_with_all_names_colon, menu_revuid): Pass a user ID in rather than a namehash, so we only have to do the hashing in one place. * packet.h, pkclist.c (build_pk_list), free-packet.c (release_public_key_parts): Remove unused namehash element for public keys. 2003-01-07 David Shaw * keygen.c (keygen_set_std_prefs): Warn when setting an IDEA preference when IDEA is not available. 2003-01-06 David Shaw * trustdb.c (get_validity_info): 'd' for disabled is not a validity value any more. * packet.h, tdbio.h, tdbio.c (tdbio_read_record, tdbio_write_record), trustdb.c (update_validity): Store temporary full & marginal counts in the trustdb. (clear_validity, get_validity_counts): Return and clear temp counts. (store_validation_status): Keep track of which keyids have been stored. (validate_one_keyblock, validate_key_list): Use per-uid copies of the full & marginal counts so they can be recalled for multiple levels. (validate_keys): Only use unused keys for each new round. (reset_unconnected_keys): Rename to reset_trust_records, and only skip specifically excluded records. * keylist.c (print_capabilities): Show 'D' for disabled keys in capabilities section. * trustdb.c (is_disabled): Remove incorrect comment. 2003-01-03 David Shaw * import.c (import_one): Only do the work to create the status display for interactive import if status is enabled. * keyring.c (keyring_search): skipfnc didn't work properly with non-keyid searches. Noted by Stefan Bellon. * getkey.c (merge_selfsigs_main): Remove some unused code and make sure that the pk selfsigversion member accounts for 1F direct sigs. 2003-01-02 Werner Koch * keydb.c (keydb_add_resource): Don't assume that try_make_homedir terminates but check again for the existence of the directory and continue then. * openfile.c (copy_options_file): Print a warning if the skeleton file has active options. 2002-12-29 David Shaw * getkey.c (merge_selfsigs_main), main.h, sig-check.c (check_key_signature2): Pass the ultimately trusted pk directly to check_key_signature2 to avoid going through the key selection mechanism. This prevents a deadly embrace when two keys without selfsigs each sign the other. 2002-12-27 David Shaw * keyserver.c (keyserver_refresh): Don't print the "refreshing..." line if there are no keys to refresh or if there is no keyserver set. * getkey.c (merge_selfsigs_main): Any valid user ID should make a key valid, not just the last one. This also fixes Debian bug #174276. 2002-12-27 Stefan Bellon * import.c (print_import_check): Changed int to size_t. 2002-12-27 David Shaw * keyedit.c (keyedit_menu, menu_revuid): Add "revuid" feature to revoke a user ID. This is the same as issuing a revocation for the self-signature, but a much simpler interface to do it. 2002-12-26 David Shaw * keydb.h, getkey.c (key_byname): Flag to enable or disable including disabled keys. Keys specified via keyid (i.e. 0x...) are always included. * getkey.c (get_pubkey_byname, get_seckey_byname2, get_seckey_bynames), keyedit.c (keyedit_menu, menu_addrevoker): Include disabled keys in these functions. * pkclist.c (build_pk_list): Do not include disabled keys for -r or the key prompt. Do include disabled keys for the default key and --encrypt-to. * trustdb.h, trustdb.c (is_disabled): New skipfnc for skipping disabled keys. * gpgv.c (is_disabled): Stub. * keygen.c (keygen_add_key_expire): Properly handle updating a key expiration to a no-expiration value. * keyedit.c (enable_disable_key): Comment. * import.c (import_one): When in interactive mode and --verbose, don't repeat some key information twice. 2002-12-22 Timo Schulz * import.c (print_import_check): New. (import_one): Use it here. Use merge_keys_and_selfsig in the interactive mode to avoid wrong key information. * status.h: Add new status code. * status.c: Ditto. 2002-12-13 David Shaw * pkclist.c (do_we_trust): Tweak language to refer to the "named user" rather than "owner". Noted by Stefan Bellon. * trustdb.h, trustdb.c (trustdb_pending_check): New function to check if the trustdb needs a check. * import.c (import_keys_internal): Used here so we don't rebuild the trustdb if it is still clean. (import_one, chk_self_sigs): Only mark trustdb dirty if the key that is being imported has any sigs other than self-sigs. Suggested by Adrian von Bidder. * options.skel: Include the required '=' sign in the sample 'group' option. Noted by Stefan Bellon. * import.c (chk_self_sigs): Don't try and check a subkey as if it was a signature. 2002-12-11 David Shaw * tdbio.c (tdbio_read_record, tdbio_write_record): Compact the RECTYPE_TRUST records a bit. * g10.c (main): Comment out --list-trust-path until it can be implemented. * import.c (import_one): Warn when importing an Elgamal primary that this may take some time (to verify self-sigs). (chk_self_sigs): Try and cache all self-sigs so the keyblock is written to the keyring with a good rich cache. * keygen.c (ask_algo): Make the Elgamal sign+encrypt warning stronger, and remove the RSA sign+encrypt warning. 2002-12-06 Stefan Bellon * options.h: Fixed typo (mangle_dos_names instead of mangle_dos_filenames). 2002-12-05 Werner Koch * g10.c: New options --[no-]mangle-dos-filenames. * options.h (opt): Added mangle-dos-filenames. * openfile.c (open_outfile) [USE_ONLY_8DOT3]: Truncate the filename only when this option is set; this is the default. 2002-12-04 David Shaw * main.h, keyedit.c, keygen.c: Back out previous (2002-12-01) change. Minimal isn't always best. * sign.c (update_keysig_packet): Use the current time rather then a modification of the original signature time. Make sure that this doesn't cause a time warp. * keygen.c (keygen_add_key_expire): Properly handle a key expiration date in the past (use a duration of 0). * keyedit.c (menu_expire): Use update_keysig_packet so any sig subpackets are maintained during the update. * build-packet.c (build_sig_subpkt): Mark sig expired or unexpired when the sig expiration subpacket is added. (build_sig_subpkt_from_sig): Handle making an expiration subpacket from a sig that has already expired (use a duration of 0). * packet.h, sign.c (update_keysig_packet), keyedit.c (menu_set_primary_uid, menu_set_preferences): Add ability to issue 0x18 subkey binding sigs to update_keysig_packet and change all callers. * trustdb.c (validate_keys): Show trust parameters when building the trustdb, and make sure that the version record update was successful. (init_trustdb): If the current parameters aren't what was used for building the trustdb, the trustdb is invalid. * tbio.c (tdbio_db_matches_options): Update to work with new trustdbs. 2002-12-03 David Shaw * tdbio.h, tdbio.c (tdbio_read_record, tdbio_write_record): Store trust model in the trustdb version record. (tdbio_update_version_record): New function to update version record values during a trustdb check or update. (tdbio_dump_record): Show trust model in dump. * trustdb.c (validate_keys): Call tdbio_update_version_record on success so that the correct options are stored in the trustdb. * options.h: rearrange trust models so that CLASSIC is 0 and OPENPGP is 1. * options.h, g10.c (main), encode.c (write_pubkey_enc_from_list), pkclist.c (algo_available), revoke.c (gen_revoke): Add --pgp8 mode. This is basically identical to --pgp7 in all ways except that signing subkeys, v4 data sigs (including expiration), and SK comments are allowed. * getkey.c (finish_lookup): Comment. * main.h, keylist.c (reorder_keyblock), keyedit.c (keyedit_menu): Reorder user ID display in the --edit-key menu to match that of the --list-keys display. * g10.c (add_notation_data): Fix initialization. 2002-12-01 David Shaw * keyedit.c (menu_expire): Don't lose key flags when changing the expiration date of a subkey. This is not the most optimal solution, but it is minimal change on the stable branch. * main.h, keygen.c (do_copy_key_flags): New function to copy key flags, if any, from one sig to another. (do_add_key_expire): New function to add key expiration to a sig. (keygen_copy_flags_add_expire): New version of keygen_add_key_expire that also copies key flags. (keygen_add_key_flags_and_expire): Use do_add_key_expire. * import.c (fix_hkp_corruption): Comment. 2002-11-25 Stefan Bellon * plaintext.c (handle_plaintext) [__riscos__]: If nooutput is set, no filetype is needed obviously. 2002-11-24 David Shaw * main.h, misc.c (default_cipher_algo, default_compress_algo): New. Return the default algorithm by trying --cipher-algo/--compress-algo, then the first item in the pref list, then s2k-cipher-algo or ZIP. * sign.c (sign_file, sign_symencrypt_file), encode.c (encode_simple, encode_crypt): Call default_cipher_algo and default_compress_algo to get algorithms. * g10.c (main): Allow pref selection for compress algo with --openpgp. * mainproc.c (proc_encrypted): Use --s2k-digest-algo for passphrase mangling rather than --digest-algo. * sign.c (hash_for): If --digest-algo is not set, but --personal-digest-preferences is, then use the first hash algorithm in the personal list. If the signing algorithm is DSA, then use the first 160-bit hash algorithm in the personal list. If --pgp2 is set and it's a v3 RSA key, use MD5. * g10.c (main), keydb.c (keydb_add_resource, keydb_locate_writable): Rename --default-keyring as --primary-keyring. Stefan wins the naming contest. 2002-11-23 David Shaw * g10.c (add_notation_data): Disallow notation names that do not contain a '@', unless --expert is set. This is to help prevent people from polluting the (as yet unused) IETF namespace. * main.h: Comments about default algorithms. * photoid.c (image_type_to_string): Comments about 3-letter file extensions. * encode.c (encode_simple), passphrase.c (passphrase_to_dek), sign.c (sign_symencrypt_file): Use --s2k-digest-algo for passphrase mangling rather than --digest-algo. 2002-11-21 David Shaw * keygen.c (keygen_set_std_prefs): Properly handle an empty preference string. * misc.c (string_to_compress_algo): "none" is a bad choice since it conflicts with the "none" in setpref. 2002-11-14 David Shaw * g10.c (main): Allow compression algorithm names as the argument to --compress-algo. The old algorithm names still work for backwards compatibility. * misc.c (string_to_compress_algo): Allow "none" as an alias for "uncompressed". 2002-11-13 Stefan Bellon * getkey.c (get_pubkey_byfprint_fast): Fixed type incompatibility, was unsigned char instead of byte. 2002-11-13 David Shaw * encode.c (encode_simple): Make sure that files larger than about 4G use partial length encoding. This is required because OpenPGP allows only for 32 bit length fields. From Werner on stable branch. * getkey.c (get_pubkey_direct): Renamed to... (get_pubkey_fast): this and made extern. (get_pubkey_byfprint_fast): New. From Werner on stable branch. * keydb.h, import.c (import_one): Use get_pubkey_fast instead of get_pubkey. We don't need a merged key and actually this might lead to recursions. (revocation_present): Likewise for search by fingerprint. From Werner on stable branch. * g10.c (main): Try to create the trustdb even for non-colon-mode list-key operations. This is required because getkey needs to know whether a a key is ultimately trusted. From Werner on stable branch. * exec.c [__CYGWIN32__]: Keep cygwin separate from Mingw32; we don't need it here as it behaves more like a Posix system. From Werner on stable branch. * passphrase.c (agent_get_passphrase): Ditto. From Werner on stable branch. * tdbio.c (MY_O_BINARY): Need binary mode with Cygwin. From Werner on stable branch. * g10.c, gpgv.c (main) [__CYGWIN32__]: Don't get the homedir from the registry. From Werner on stable branch. * keyedit.c (show_key_with_all_names_colon): Make --with-colons --edit display match the validity and trust of --with-colons --list-keys. * passphrase.c (agent_send_all_options): Fix compile warning. * keylist.c (list_keyblock_colon): Validity for subkeys should match that of the primary key, and not that of the last user ID. * getkey.c (merge_selfsigs): Revoked/expired/invalid primary keys carry these facts onto all their subkeys, but only after the subkey has a chance to be marked valid. This is to fix an incorrect "invalid public key" error verifying a signature made by a revoked signing subkey, with a valid unrevoked primary key. 2002-11-09 Werner Koch * passphrase.c (agent_send_all_options): Use tty_get_ttyname to get the default ttyname. 2002-11-07 David Shaw * keyring.h, keyring.c (keyring_register_filename): Return the pointer if a given keyring is registered twice. * keydb.h, keydb.c (keydb_add_resource): Use flags to indicate a default keyring. (keydb_locate_writable): Prefer the default keyring if possible. * g10.c (main): Add --default-keyring option. 2002-11-06 David Shaw * options.h, g10.c (main), trustdb.c (ask_ownertrust): Add --force-ownertrust option for debugging purposes. This allows setting a whole keyring to a given trust during an --update-trustdb. Not for normal use - it's just easier than hitting "4" all the time to test a large trustdb. * pubkey-enc.c (get_session_key): With hidden recipients or try a given passphrase against all secret keys rather than trying all secret keys in turn. Don't if --try-all-secrets or --status-fd is enabled. * passphrase.c (passphrase_to_dek): Mode 1 means do a regular passphrase query, but don't prompt with the key info. * seckey-cert.c (do_check, check_secret_key): A negative ask count means to enable passphrase mode 1. * keydb.h, getkey.c (enum_secret_keys): Add flag to include secret-parts-missing keys (or not) in the list. 2002-11-05 David Shaw * keyserver.c (keyserver_search_prompt): When --with-colons is enabled, don't try and fit the search output to the screen size - just dump the whole list. 2002-11-04 David Shaw * keyserver.c (keyserver_search_prompt): When --with-colons is enabled, just dump the raw keyserver protocol to stdout and don't print the menu. * keyserver.c (show_prompt): Don't show a prompt when command-fd is being used. * trustdb.c (trust_model_string, check_trustdb, update_trustdb, validate_one_keyblock): It's not clear what a trustdb rebuild or check means with a trust model other than "classic" or "openpgp", so disallow this. 2002-11-03 David Shaw * options.h, g10.c (main): Add --trust-model option. Current models are "openpgp" which is classic+trustsigs, "classic" which is classic only, and "always" which is the same as the current option --always-trust (which still works). Default is "openpgp". * trustdb.c (validate_one_keyblock): Use "openpgp" trust model to enable trust sigs. * gpgv.c (main), mainproc.c (check_sig_and_print), pkclist.c (do_we_trust, do_we_trust_pre, check_signatures_trust): Use new --trust-model option in place of --always-trust. * keyedit.c (sign_mk_attrib, trustsig_prompt, sign_uids, keyedit_menu): Prompt for and create a trust signature with "tsign". This is functional, but needs better UI text. * build-packet.c (build_sig_subpkt): Able to build trust and regexp subpackets. * pkclist.c (do_edit_ownertrust): Comment. 2002-11-02 David Shaw * keygen.c (set_one_pref, keygen_set_std_prefs): Allow using the full algorithm name (CAST5, SHA1) rather than the short form (S3, H2). * main.h, keygen.c (keygen_get_std_prefs), keyedit.c (keyedit_menu): Return and use a fake uid packet rather than a string since we already have a nice parser/printer in keyedit.c:show_prefs. * main.h, misc.c (string_to_compress_algo): New. 2002-11-01 David Shaw * g10.c (main): Add --no-throw-keyid. * keydb.h, encode.c (write_pubkey_enc_from_list), g10.c (main), pkclist.c (build_pk_list): Add --hidden-recipient (-R) and --hidden-encrypt-to, which do a single-user variation on --throw-keyid. The "hide this key" flag is carried in bit 0 of the pk_list flags field. * keyserver.c (parse_keyrec): Fix shadowing warning. 2002-10-31 Stefan Bellon * compress.c (init_compress) [__riscos__]: Use riscos_load_module() to load ZLib module. * g10.c (main) [__riscos__]: Renames due to changes in riscos.c (e.g. prefixes all RISC OS specific functions with riscos_*). * photoid.c (show_photos) [__riscos__]: Likewise. * signal.c (got_fatal_signal) [__riscos__]: Likewise. * trustdb.c (check_regexp) [__riscos__]: Branch to RISC OS RegEx handling. 2002-10-31 David Shaw * build-packet.c (do_plaintext), encode.c (encode_sesskey, encode_simple, encode_crypt), sign.c (write_plaintext_packet): Use wipememory() instead of memset() to wipe sensitive memory as the memset() might be optimized away. 2002-10-30 David Shaw * trustdb.c (check_regexp): Modern regexps require REG_EXTENDED. 2002-10-29 David Shaw * packet.h, trustdb.h, trustdb.c (trust_string): New. Return a string like "fully trusted", "marginally trusted", etc. (get_min_ownertrust): New. Return minimum ownertrust. (update_min_ownertrust): New. Set minimum ownertrust. (check_regexp): New. Check a regular epression against a user ID. (ask_ownertrust): Allow specifying a minimum value. (get_ownertrust_info): Follow the minimum ownertrust when returning a letter. (clear_validity): Remove minimum ownertrust when a key becomes invalid. (release_key_items): Release regexp along with the rest of the info. (validate_one_keyblock, validate_keys): Build a trust sig chain while validating. Call check_regexp for regexps. Use the minimum ownertrust if the user does not specify a genuine ownertrust. * pkclist.c (do_edit_ownertrust): Only allow user to select a trust level greater than the minimum value. * parse-packet.c (can_handle_critical): Can handle critical trust and regexp subpackets. * trustdb.h, trustdb.c (clear_ownertrusts), delkey.c (do_delete_key), import.c (import_one): Rename clear_ownertrust to clear_ownertrusts and have it clear the min_ownertrust value as well. * keylist.c (list_keyblock_print): Indent uid to match pub and sig. * keyedit.c (print_and_check_one_sig, show_key_and_fingerprint, menu_addrevoker), keylist.c (list_keyblock_print, print_fingerprint): Show "T" or the trust depth for trust signatures, and add spaces to some strings to make room for it. * packet.h, parse-packet.c (dump_sig_subpkt, parse_one_sig_subpkt, parse_signature): Parse trust signature values. * tdbio.h, tdbio.c (tdbio_read_record, tdbio_write_record): Reserve a byte for the minimum ownertrust value (for use with trust signatures). 2002-10-29 Stefan Bellon * build-packet.c (calc_plaintext, do_plaintext): Removed RISC OS specific filetype parts (it's now done in make_basename()). * plaintext.c (handle_plaintext): Tidied up RISC OS specific filetype parts. * encode.c (encode_simple, encode_crypt): Added argument to make_basename() call. * sign.c (write_plaintext_packet): Added argument to make_basename() call. 2002-10-28 Stefan Bellon * build-packet.c (calc_plaintext, do_plaintext): Added filetype handling for RISC OS' file types. * plaintext.c (handle_plaintext) [__riscos__]: Added filetype handling for RISC OS' file types. 2002-10-23 David Shaw * main.h, import.c (sec_to_pub_keyblock, import_secret_one, parse_import_options), g10.c (main): New import-option "convert-sk-to-pk" to convert a secret key into a public key during import. It is on by default. 2002-10-23 Werner Koch * pubkey-enc.c (get_it): Fix segv, test for revoked only when PK has been assigned. 2002-10-18 Timo Schulz * keylist.c: (print_pubkey_info): New. (print_seckey_info): New. * main.h: Prototypes for the new functions. * delkey.c (do_delete_key): Use it here. * revoke.c (gen_desig_revoke): Ditto. 2002-10-17 Werner Koch * pkclist.c (do_edit_ownertrust): Show all user IDs. This should be enhanced to also show the current trust level. Suggested by Florian Weimer. 2002-10-17 David Shaw * g10.c (main): Handle --strict and --no-strict from the command line before the options file is loaded. 2002-10-15 David Shaw * g10.c (main): Disable --textmode when encrypting (symmetric or pk) in --pgp2 mode as PGP 2 can't handle the unknown length literal packet. Reported by Michael Richardson. 2002-10-14 David Shaw * keyserver-internal.h, keyserver.c (print_keyrec, parse_keyrec, show_prompt, keyserver_search_prompt, keyserver_spawn): Go to version 1 of the keyserver protocol. This is a better design, similar to --with-colons, that allows for keys with multiple user IDs rather than using multiple keys. It also matches the machine readable pksd format. Also use a prettier --search-keys listing format that can fill different size windows (currently set at 24 lines). 2002-10-12 Werner Koch * keygen.c (print_status_key_created): New. (do_generate_keypair): Use it to print the fingerprint. (generate_subkeypair): Likewise. 2002-10-11 David Shaw * keyedit.c (menu_addrevoker): Properly back out if the signature fails. Also, do not allow appointing the same revoker twice, and report ALREADY_SIGNED if the user tries it. 2002-10-07 David Shaw * import.c (import_keys_internal): Missed one s/inp/inp2/. * keylist.c (print_capabilities): Properly indicate per-key capabilities of sign&encrypt primary keys that have secret-parts-missing (i.e. no capabilities at all) * mainproc.c (symkey_decrypt_sesskey): Fix compiler warning. 2002-10-04 David Shaw * getkey.c (get_pubkey_direct): Don't cache keys retrieved via this function as they may not have all their fields filled in. * sig-check.c (signature_check2): Use new is_primary flag to check rather than comparing main_keyid with keyid as this still works in the case of a not fully filled in pk. 2002-10-04 Werner Koch * import.c (import_keys_internal): s/inp/inp2/ to avoid shadowing warning. * passphrase.c (agent_get_passphrase): Fixed signed/unsigned char problem in %-escaping. Noted by Ingo Klöcker. 2002-10-03 David Shaw * options.h, g10.c (main): Add --strict and --no-strict to switch the log_warning severity level from info to error. * keylist.c (print_capabilities): Secret-parts-missing keys should show that fact in the capabilities, and only primary signing keys can certify other keys. * packet.h, parse_packet.c (parse_key): Add is_primary flag for public keys (it already exists for secret keys). 2002-10-02 David Shaw * import.c (import_secret_one): Check for an illegal (>110) protection cipher when importing a secret key. * keylist.c (list_keyblock_print): Show a '#' for a secret-parts-missing key. * parse_packet.c (parse_key): Some comments. * revoke.c (gen_revoke): Remove some debugging code. * trustdb.c (verify_own_keys): Make trusted-key a non-deprecated option again. * seckey-cert.c (do_check): Don't give the IDEA warning unless the cipher in question is in fact IDEA. 2002-10-01 David Shaw * import.c (import_one): Make sure that a newly imported key starts with a clean ownertrust. 2002-10-01 Werner Koch * getkey.c (get_pubkey_direct): New. (merge_selfsigs_main): Use it here to look for an ultimately trusted key. Using the full get_pubkey might lead to an infinitive recursion. 2002-09-29 David Shaw * keyserver.c (parse_keyserver_uri): Force the keyserver URI scheme to lowercase to be case-insensitive. 2002-09-28 David Shaw * export.c (do_export_stream): Comment. * sig-check.c (check_key_signature2): Properly handle a non-designated revocation import. 2002-09-26 Werner Koch * g10.c (set_homedir): New. Changed all direct assignments to use this. * gpgv.c (set_homedir): Ditto. 2002-09-25 David Shaw * Makefile.am: Link gpg with EGDLIBS (i.e. NETLIBS) as EGD uses sockets. Remove the old NETLIBS variable since the keyserver stuff is no longer internal. 2002-09-24 David Shaw * import.c (import_keys_stream): Fix compiler type warning. * keyring.c (keyring_rebuild_cache), sig-check.c (check_key_signature2), import.c (import, chk_self_sigs): Minor language cleanups. 2002-09-23 Stefan Bellon * main.h: Introduced fast-import as import option. Removed fast as separate option from prototypes. * import.c (parse_import_options): Added fast-import option. (import_*): Removed fast as separate option. * g10.c (main): Added option fast-import, removed old fast as separate argument. * keyserver.c (keyserver_spawn): Removed old fast as separate argument. 2002-09-22 Stefan Bellon * import.c (import_keys, import_keys_stream, import_keys_internal): Added trustdb update/check to key import if not fast-import and interactive set/no-auto-check-trustdb unset. Avoided function clone by introducing import_keys_internal. 2002-09-19 David Shaw * keyserver.c (keyserver_spawn): Properly handle line truncation. Don't leak memory (~10-20 bytes) on searches. (keyserver_search_prompt): Cleanup. * keylist.c (list_keyblock_colon): Show 1F direct key signatures in --with-colons listing. 2002-09-16 David Shaw * keyedit.c (menu_addrevoker): The direct key signature for revocation keys must be at least v4 to carry the revocation key subpacket. Add a PGP 2.x warning for revocation keys. 2002-09-14 David Shaw * g10.c (check_permissions): Rearrange strings to make translating easier (don't incorporate string parts). * keyedit.c (sign_uids): Make strings translatable. * sig-check.c (check_key_signature2): Make string translatable. 2002-09-13 David Shaw * getkey.c (check_revocation_keys): Move.... * main.h, sig-check.c (check_revocation_keys): to here. Also return the signature_check error code rather than 0/1 and cache the sig result. * sig-check.c (check_key_signature2): Divert to check_revocation_keys if a revocation sig is made by someone other than the pk owner. * getkey.c (merge_selfsigs_main): Tidy. 2002-09-13 Werner Koch * g10.c (main) [__MINGW32__]: Activate oLoadExtension. 2002-09-12 David Shaw * Makefile.am, hkp.c, hkp.h, keyserver.c (keyserver_work): Remove internal HKP support. * keyserver.c (keyserver_spawn): Remove whitespace after keyserver commands. 2002-09-10 David Shaw * exec.c (expand_args): Remove loop left over from earlier implementation. (exec_write): Missed one tick. 2002-09-10 Werner Koch * g10.c, options.h: Removed option --emulate-checksum-bug. * misc.c (checksum_u16_nobug): Removed. (checksum_u16): Removed the bug emulation. (checksum_mpi): Ditto. (checksum_mpi_counted_nbits): Removed and replaced all calls with checksum_mpi. * parse-packet.c (read_protected_v3_mpi): New. (parse_key): Use it here to store it as an opaque MPI. * seckey-cert.c (do_check): Changed the v3 unprotection to the new why to store these keys. (protect_secret_key): Likewise. * build-packet.c (do_secret_key): And changed the writing. * tdbio.c (tdbio_set_dbname, open_db): Use new macro MY_O_BINARY to avoid silly ifdefs. (open_db): Fallback to RDONLY so that gpg may be used from a RO-medium. * encode.c (encode_simple): Make sure we don't use an ESK packet when we don't have a salt in the S2K. * misc.c (pct_expando) : Make sure that LEN is initialized. * exec.c (exec_finish): Use ticks to denote filenames in messages. (make_tempdir, exec_write): Changed format of messages. * keyserver.c (print_keyinfo): Release USERID in on error. (keyserver_work) [!DISABLE_KEYSERVER_HELPERS]: Exclude the unused code. 2002-09-09 Werner Koch * parse-packet.c (make_attribute_uidname): Add new ar MAX_NAMELEN for sanity checks. Changed both callers. Limit the size of an %s. * options.skel: Comment lock-once out, so that this file does not change anything when copied to a new home directory. * openfile.c (try_make_homedir): Don't exit after copying the option skeleton. * options.h: Don't use a comma when declaring variables over more than one line. * mainproc.c (symkey_decrypt_sesskey): Check length of the session key. * hkp.c (dehtmlize): Use ascii_tolower to protect against weird locales. Cast the argument for isspace for the sake of broken HP/UXes. (parse_hkp_index): s/ascii_memcasecmp/ascii_strncasecmp/. * g10.c: Removed option --emulate-3des-s2k-bug. * passphrase.c (hash_passphrase): Was used here. * export.c (parse_export_options) * keyserver.c (parse_keyserver_options) * import.c (parse_import_options) * g10.c (check_permissions): s/ascii_memcasecmp/ascii_strncasecmp/. 2002-09-09 David Shaw * g10.c (add_group): Use '=' to separate group name from group members. Use a better error message for when no = is found. * hkp.c (hkp_export): Use CRLF in headers. 2002-09-03 David Shaw * mainproc.c (print_pkenc_list): Don't increment the error counter when printing the list of keys a message was encrypted to. This would make gpg give a non-zero exit code even for completely valid messages if the message was encrypted to more than one key that the user owned. 2002-09-02 Werner Koch * g10.c (main): Try to set a default character set. Print the used one in verbosity level 3. * gpgv.c (main): Try to set a default character set. * status.c, status.h (STATUS_IMPORT_OK): New. * import.c (import_one,import_secret_one): Print new status. 2002-08-30 David Shaw * pkclist.c (build_pk_list): Add new status code to indicate an untrusted user. This (or a disabled key) fail with "unavailable pubkey" (G10ERR_UNU_PUBKEY). * pkclist.c (build_pk_list): Fail if any recipient keys are unusable. * options.skel: The PGP LDAP keyserver is back. Use MIT keyserver as a sample rather than cryptnet as cryptnet does not support searching yet. * keyedit.c (show_key_with_all_names): Fix error message (preferences are userid/selfsig and not key specific). 2002-08-30 Werner Koch * pkclist.c (do_we_trust_pre): Changed the wording of a warning. * encode.c (encode_simple,encode_crypt): Use new style CTB for compressssed packets when using MDC. We need to do this so that concatenated messages are properly decrypted. Old style compression assumes that it is the last packet; given that we can't determine the length in advance, the uncompressor does not know where to start. Actually we should use the new CTB always but this would break PGP 2 compatibility. * parse-packet.c (parse): Special treatment for new style CTB compressed packets. * build-packet.c (do_mdc): Removed. Was not used. (do_encrypted_mdc): Count in the version number and the MDC packet. 2002-08-28 David Shaw * sig-check.c (do_check_messages, do_check): Show keyid in error messages. * keyserver.c (print_keyinfo): More readable key listings for --search-keys responses. 2002-08-26 David Shaw * hkp.c (parse_hkp_index, dehtmlize): Move HTML functionality into new "dehtmlize" function. Remove HTML before trying to parse each line from the keyserver. If the keyserver provides key type information in the listing, use it. 2002-08-23 David Shaw * sig-check.c (do_check, do_check_messages): Emit the usual sig warnings even for cached sigs. This also serves to protect against missing a sig expiring while cached. * getkey.c (merge_selfsigs_main): Don't check UID self-sigs twice. 2002-08-22 David Shaw * import.c (clean_subkeys, chk_self_sigs): Merge clean_subkeys into chk_self_sigs. This improves efficiency as the same signatures are not checked multiple times. Clarify when a subkey is revoked (any revocation signature, even if it is dated before the binding signature). * getkey.c (merge_selfsigs_subkey): Subkey revocation comments. * keylist.c (list_one): Stats are only for public key listings. * g10.c (main), options.skel: Default should be include-revoked for keyserver operations. 2002-08-21 Werner Koch * import.c (import_print_stats): Print new non_imported counter which is currently not used because we terminate on errors. 2002-08-20 David Shaw * options.skel: Document no-include-attributes for keyserver-options. * keylist.c, keyedit.c, keyserver.c, sign.c: Some TODOs and comments. * export.c (do_export_stream): Fix noop bug in exporting sensitive revocation keys. * pkclist.c (do_edit_ownertrust): Comment out the option for showing trust paths until it can be implemented. 2002-08-19 Werner Koch * getkey.c (get_user_id_native): Renamed to .. (get_user_id_printable): this. Filter out all dangerous characters. Checked all usages. (get_user_id_string_native): Renamed to.. (get_user_id_string_printable): this. Filter out all dangerous characters. Checked all usages. * keyedit.c (show_basic_key_info): New. * keylist.c (print_fingerprint): New mode 3. * import.c (import_one): Use new function to display the user ID. 2002-08-16 Timo Schulz * g10.c (main): Enable opt.interactive. * import.c (import_one): Ask the user if the key shall be imported when the interactive mode is used. Useful to extract selected keys from a file. 2002-08-16 Werner Koch * seckey-cert.c: Workaround to allow decryption of v3 keys created with a bug in the mpi_get_secure_buffer. 2002-08-14 David Shaw * hkp.c (parse_hkp_index): Properly handle really large keys (5 digit key length) in HKP searches. 2002-08-13 David Shaw * encode.c (encode_simple): Fix problem with using compression algo 2 and symmetric compressed files. * encode.c (encode_simple, encode_crypt): If we are not using a MDC, compress even if a file is already compressed. This is to help against the chosen ciphertext attack. * pkclist.c (select_algo_from_prefs): Fix requested algorithm bug so the request succeeds even if the requested algorithm is not the first found. * cipher.c (write_header), encode.c (use_mdc, encode_simple, encode_crypt, encrypt_filter), g10.c (main): Be more eager to use a MDC. We use a MDC if the keys directly support it, if the keys list AES (any) or TWOFISH anywhere in the prefs, or if the cipher chosen does not have a 64 bit blocksize. 2002-08-08 David Shaw * options.skel: Some language tweaks, and remove the load-extension section for random gatherers. * keyring.c (create_tmp_file, rename_tmp_file): Create tmp files with user-only permissions, but restore the original permissions if the user has something special set. * openfile.c (copy_options_file): Create new options file (gpg.conf) with user-only permissions. * keydb.c (keydb_add_resource): Create new keyrings with user-only permissions. * tdbio.c (tdbio_set_dbname): Create new trustdbs with user-only permissions. 2002-08-07 David Shaw * sig-check.c (signature_check2): Sanity check that the md has a context for the hash that the sig is expecting. This can happen if a onepass sig header does not match the actual sig, and also if the clearsign "Hash:" header is missing or does not match the actual sig. * keyedit.c (menu_revsig): Properly show a uid is revoked without restarting gpg. This is Debian bug 124219, though their supplied patch will not do the right thing. * main.h, tdbio.c (tdbio_set_dbname), misc.c (removed check_permissions), keydb.c (keydb_add_resource), g10.c (main, check_permissions): Significant reworking of the permission check mechanism. The new behavior is to check everything in the homedir by checking the homedir itself. If the user wants to put (possibly shared) keyrings outside the homedir, they are not checked. The options file and any extension files are checked wherever they are, as well as their enclosing directories. This is Debian bug 147760. 2002-08-06 Stefan Bellon * g10.c (main): Use of EXTSEP_S in new gpg.conf string. * openfile.c (copy_options_file): Ditto. 2002-08-06 David Shaw * options.h, g10.c (main), mainproc.c (proc_encrypted): --ignore-mdc-error option to turn a MDC check error into a warning. * encode.c (encode_crypt), g10.c (main), sign.c (sign_file, clearsign_file): Use the same --pgpX warning string everywhere to ease translations. * encode.c (write_pubkey_enc_from_list): Warn when using --throw-keyid with --pgpX. Noted by Vedaal Nistar. * revoke.c (export_minimal_pk, gen_desig_revoke, gen_revoke): Export a minimal pk along with the revocation cert when in --pgpX mode so that PGP can import it. 2002-08-06 Werner Koch * options.skel: Changed comments. * g10.c (main): Try to use "gpg.conf" as default option file. * openfile.c (copy_options_file): Changed name of created file. 2002-08-02 Werner Koch * Makefile.am (LDFLAGS): Removed DYNLINK_LDFLAGS. 2002-07-30 David Shaw * options.h, g10.c (main), mainproc.c (proc_encrypted): Return a decryption failed error if a MDC does not verify. Warn if a MDC is not present (can disable via --no-mdc-warning). * exec.c (exec_write), g10.c (main), keyserver.c (keyserver_spawn): Use new DISABLE_KEYSERVER_PATH rather than FIXED_EXEC_PATH. 2002-07-28 David Shaw * sig-check.c (do_check): Properly validate v4 sigs with no hashed section at all. 2002-07-25 Werner Koch * delkey.c (do_delete_key): Always allow to delete a key in batch mode when specified by fingerprint. Suggested by Enzo Michelangeli. 2002-07-25 David Shaw * keyedit.c (menu_revsig): Change "revsig" to honor selected uids so the user can revoke sigs from particular uids only. * keylist.c (list_keyblock_print): Don't display expired uids in --list-keys unless -v and not --list-sigs (just like revoked uids). * exec.c, export.c, import.c, keyedit.c, keyserver.c, misc.c: "Warning" -> "WARNING" 2002-07-24 David Shaw * main.h, import.c (parse_import_options, fix_hkp_corruption, import_one, delete_inv_parts), g10.c (main): New import-option "repair-hkp-subkey-bug", which repairs as much as possible the HKP mangling multiple subkeys bug. It is on by default for keyserver receives, and off by default for regular --import. * main.h, import.c (import, import_one, delete_inv_parts), hkp.c (hkp_ask_import), keyserver.c (keyserver_spawn): Use keyserver import options when doing keyserver receives. * options.h, exec.h, exec.c (set_exec_path, exec_write), g10.c (main), keyserver.c (keyserver_spawn): If the user does not use "exec-path", completely replace $PATH with GNUPG_LIBEXECDIR before calling the keyserver helper. If the user does use "exec-path", append GNUPG_LIBEXECDIR after the specified path. 2002-07-23 David Shaw * import.c (parse_import_options), export.c (parse_export_options): Fix offset problem with reversed ("no-") meanings. * import.c (delete_inv_parts): Discard subkey signatures (0x18 and 0x28) if found in the userid section of the key. * sig-check.c (signature_check2): Signatures made by invalid subkeys (bad/missing binding sig) are also invalid. * keylist.c (print_fingerprint): Show the primary as well as the secondary key fingerprint in modes 1 & 2. 2002-07-22 David Shaw * options.h, main.h, g10.c (main), import.c (parse_import_options, delete_inv_parts), keyserver.c (parse_keyserver_options): add new --import-options option. The only current flag is "allow-local-sigs". * g10.c (main): Don't disable MDC in pgp7 mode. * options.h, g10.c (main), keyserver.c (parse_keyserver_options): Remove old keyserver-option include-attributes now that there is an export-option for the same thing. * options.h, main.h, export.c (parse_export_options, do_export_stream), g10.c (main): add new --export-options option. Current flags are "include-non-rfc", "include-local-sigs", "include-attributes", and "include-sensitive-revkeys". * options.h, hkp.c (hkp_export), keyserver.c (parse_keyserver_options, keyserver_spawn): try passing unknown keyserver options to export options, and if successful, use them when doing a keyserver --send-key. * build-packet.c (build_sig_subpkt): We do not generate SIGSUBPKT_PRIV_VERIFY_CACHE anymore. * revoke.c (gen_desig_revoke): Lots more comments about including sensitive revkeys along with the revocation sig itself. * keyserver.c (parse_keyserver_options): Simpler implementation that can skip one pass over the options. 2002-07-18 David Shaw * keyedit.c (keyedit_menu, menu_addrevoker): Allow specifying "sensitive" as an argument to an addrevoker command. This sets the 0x40 sensitive revoker flag. * revoke.c (gen_desig_revoke): When generating a designated revocation, include the direct key sig that contains the designated revoker subpacket. This allows sensitive designated revocation subpackets to be exported. Also indicate which revokers are sensitive in the first place. 2002-07-17 David Shaw * keyedit.c (show_key_with_all_names_colon): The 0x40 class bit in a designated revoker means "sensitive", not "local". It's exportable under the right circumstances. * main.h, options.h, export.c (do_export_stream), g10.c (main), hkp.c (hkp_export), keyserver.c (keyserver_spawn: Add a flag to skip attribute packets and their signatures while exporting. This is to accomodate keyservers (pksd again) that choke on attributes. Use keyserver-option "include-attributes" to control it. This defaults to ON (i.e. don't skip). 2002-07-09 David Shaw * options.h, keyserver.c (parse_keyserver_uri, keyserver_spawn, keyserver_work), hkp.c (hkp_ask_import, hkp_export, hkp_search): Use a much more strict reading of RFC-2396 for the keyserver URIs. Specifically, don't try and be smart about checking the value of ":port" so long as it is all digits, and properly handle opaque data (those scheme specific parts that do not start with "//"). 2002-07-04 David Shaw * photoid.c (get_default_photo_command, show_photos): Honor FIXED_PHOTO_VIEWER and DISABLE_PHOTO_VIEWER. * mainproc.c (check_sig_and_print): Use --show-photos to show photos when verifying a sig made by a key with a photo. * keyserver.c (parse_keyserver_uri): Properly parse a URI with no :port section and an empty file path, but with a terminating '/'. (keyserver_work): Honor DISABLE_KEYSERVER_HELPERS. * hkp.c (hkp_ask_import): Display keyserver URI as a URI, but only if verbose. * exec.c, g10.c: USE_EXEC_PATH -> FIXED_EXEC_PATH 2002-07-03 David Shaw * exec.h, exec.c (set_exec_path, exec_write), g10.c (main): If USE_EXEC_PATH is defined at compile time, use it to lock the exec-path and not allow the user to change it. 2002-07-02 David Shaw * options.h, g10.c (main), keyserver.c (keyserver_refresh): Maintain and use the original keyserver URI for cosmetics rather than trying to recreate it when needed. * mainproc.c (check_sig_and_print): Properly disregard expired uids. Make sure that the first uid listed is a real uid and not an attribute (attributes should only be listed in the "aka" section). When there are no valid textual userids, try for an invalid textual userid before using any attribute uid. 2002-07-01 David Shaw * options.skel: Fix a few typos, clarify "group", and remove sample photo viewers for Win32 since they are the defaults now. * parse-packet.c (make_attribute_uidname), keylist.c (dump_attribs): Fix two typecast warnings. * packet.h, build-packet.c (build_attribute_subpkt), exec.c (expand_args), mkdtemp.c (mkdtemp), photoid.c (parse_image_header): Fix some signedness compiler warnings. 2002-07-01 Werner Koch * photoid.c (get_default_photo_command): Also use __MINGW32__ instead of HAVE_DOSISH_SYSTEM. * encode.c (encode_symmetric): Do not use the new encryption code. 2002-06-30 Werner Koch * photoid.c: Use __MINGW32__ to include windows because HAVE_DOSISH_SYSTEM is also set for OS/2 and plain DOS. Provide constant missing in older mingw installations. 2002-06-21 Stefan Bellon * g10.c [__riscos__]: Moved RISC OS specific stuff to util/riscos.c and include/util.h. * gpgv.c [__riscos__]: Likewise. 2002-06-20 David Shaw * keydb.h, pkclist.c (select_algo_from_prefs): Allow passing a suggested algorithm which will be used if available. * encode.c (encode_crypt, encrypt_filter), sign.c (sign_file): Use new select_algo_from_prefs feature to check if forcing an algorithm would violate the recipient preferences. * photoid.c (get_default_photo_command, show_photos): Use different default viewers on different platforms. Currently we have Win 9x, Win NT (2k, xp), Mac OSX, RISC OS, and "everybody else". These are #ifdefs as much as possible to avoid clutter. * g10.c (strusage, build_list), keyedit.c (show_prefs), main.h, misc.c (compress_algo_to_string, check_compress_algo), pkclist.c (algo_available), keygen.c (keygen_set_std_prefs): New algo_to_string and check functions for compress algorithms. 2002-06-20 Werner Koch * misc.c (setsysinfo): Removed a #warning for Alpha's uniligedn trap disabling - it is quite possible that this is a debug relict. 2002-06-20 Stefan Bellon * g10.c [__riscos__]: Added image file system feature. * gpgv.c [__riscos__]: Added image file system feature. * photoid.c (show_photos) [__riscos__]: Set RISC OS filetype of photo id according to MIME type. 2002-06-19 David Shaw * hkp.c (parse_hkp_index): Don't leak memory when failing out of a bad HKP keyserver. * g10.c (add_notation_data): Relax slightly the rules as to what can go into a notation name - 2440 allows "@", for example. 2002-06-17 David Shaw * import.c (clean_subkeys, import_one): Only allow at most 1 binding sig and at most 1 revocation sig on a subkey, as per 2440:11.1. * hkp.c (parse_hkp_index, hkp_search): Error if the keyserver returns an unparseable HKP response. 2002-06-15 David Shaw * keyedit.c (show_key_with_all_names), keylist.c (list_keyblock_print): Show "[expired]" before expired uids. * keyedit.c (show_key_with_all_names_colon), mainproc.c (list_node), keylist.c (list_keyblock_colon): Show flag 'e' for expired user ids. Use "uat" for user attribute packets instead of "uid". Also use ' ' rather than the fake user id string on attributes. * keygen.c (keygen_add_revkey): Remove unused code. * misc.c (check_permissions): Check directory permissions properly - they are not special files. * pkclist.c (expand_id, expand_group, build_pk_list): When expanding groups before building a pk list, inherit flags from the original pre-expanded string. * pubkey-enc.c (is_algo_in_prefs): Don't use prefs from expired uids. 2002-06-14 David Shaw * free-packet.c (copy_signature): Properly copy a signature that carries a revocation key on it. * pkclist.c (expand_id, expand_group, build_pk_list): Groups now work properly when used in the "Enter the user ID" prompt. 2002-06-14 David Shaw * keyedit.c (show_key_with_all_names): Display warning if a user tries to show prefs on a v3 key with a v3 selfsig. * kbnode.c (dump_kbnode): Show if a uid is expired. * import.c (merge_blocks, import_revoke_cert): Show user ID receiving a revocation certificate. * free-packet.c (cmp_user_ids): Properly compare attribute ids. * pkclist.c (expand_groups): Maintain the strlist flags while expanding. Members of an expansion inherit their flags from the expansion key. * options.h, cipher.c (write_header), g10.c (main), keygen.c (keygen_set_std_prefs): remove the personal_mdc flag. It no longer serves a purpose now that the personal preference lists are split into cipher/digest/zip. 2002-06-14 Timo Schulz * skclist.c (is_insecure): Implemented. 2002-06-12 David Shaw * keyserver.c (keyserver_spawn): Properly handle PROGRAM responses when they have a CRLF ending. Noted by Keith Ray. * keyserver.c (keyserver_spawn): Handle CRLF endings from keyserver helpers. Also don't leak the last line worth of memory from the keyserver response. * main.h, misc.c (deprecated_warning): New function to warn about deprecated options and commands. * g10.c (main), keyserver-internal.h, keyserver.c (parse_keyserver_uri): Use new deprecated function to warn about honor-http-proxy, auto-key-retrieve, and x-broken-hkp. 2002-06-11 David Shaw * Makefile.am: link gpg with NETLIBS for the built-in HKP access. 2002-06-10 David Shaw * options.h, keyserver.c (keyserver_opts), g10.c (main): New keyserver option "include-subkeys". This feature already existed, but now can be turned off. It defaults to on. * options.h, keyserver.c (parse_keyserver_options, keyserver_spawn): There are now enough options to justify making a structure for the keyserver options rather than a page of if-then-else-if-then-etc. * getkey.c (merge_keys_and_selfsig, merge_selfsigs_main): Fix bug in calculating key expiration dates. 2002-06-09 David Shaw * keydb.h, getkey.c (get_user_id_native), import.c (import_one): Display user ID while importing a key. Note this applies to both --import and keyserver --recv-keys. * exec.c (exec_finish): Log unnatural exit (core dump, killed manually, etc) for fork/exec/pipe child processes. 2002-06-08 Timo Schulz * encode.c (encode_symmetric): Disable the compat flag when the expert mode is enabled. 2002-06-07 David Shaw * options.skel, options.h, main.h, keydb.h, pkclist.c (build_pk_list, expand_groups), g10.c (main, add_group): Add new "group" command to allow one name to expand into multiple keys. For simplicity, and to avoid potential loops, we only expand once - you can't make an alias that points to an alias. * main.h, g10.c (main), keygen.c (build_personal_digest_list): Simplify the default digest list - there is really no need for the other hashes since they will never be used after SHA-1 in the list. * options.skel, options.h, g10.c (main), hkp.c (hkp_ask_import, hkp_export, hkp_search), keyserver.c (parse_keyserver_options, parse_keyserver_uri, keyserver_work, keyserver_refresh): Make the "x-broken-hkp" keyserver scheme into keyserver-option "broken-http-proxy". Move honor_http_proxy into keyserver_options. Canonicalize the three variations of "hkp", "x-hkp", and "x-broken-hkp" into "hkp". 2002-06-07 Stefan Bellon * g10.c [__riscos__]: Added --attribute-file to do the same as --attribute-fd, but with a filename not a fd as argument. Added magic symbol for RISC OS to use different memory management. * gpgv.c [__riscos__]: Added magic symbol for RISC OS to use different memory management. 2002-06-06 David Shaw * main.h, g10.c (main), keygen.c (build_personal_digest_list): Put in a default digest preference list consisting of SHA-1, followed by every other installed digest except MD5. Note this is the same as having no digest preference at all except for SHA-1 being favored. * options.h, g10.c (main), keygen.c (keygen_set_std_prefs), pkclist.c (select_algo_from_prefs): Split --personal-preference-list into three: --personal-{cipher|digest|compress}-preferences. This allows a user to set one without affecting another (i.e. setting only a digest pref doesn't imply an empty cipher pref). * exec.c (exec_read): This is a safer way of guessing the return value of system(). Noted by Stefan Bellon. 2002-06-05 David Shaw * hkp.c (parse_hkp_index): Be more robust with keyservers returning very unparseable responses. * exec.c (exec_read): Catch and display an error when the remote process exits unnaturally (i.e. segfault) so the user knows what happened. Also fix exec_write stub which has a different number of arguments now. 2002-06-05 Timo Schulz * encode.c (encode_simple): Ignore the new mode for RFC1991. * mainproc.c (symkey_decrypt_sesskey): Better check for weird keysizes. 2002-06-05 Timo Schulz * encode.c (encode_sesskey): New. (encode_simple): Use it here. But by default we use the compat mode which supress to generate encrypted session keys. 2002-06-05 Timo Schulz * mainproc.c (symkey_decrypt_sesskey): New. (proc_symkey_enc): Support for encrypted session keys. 2002-06-04 David Shaw * sign.c (hash_for, sign_file): When encrypting and signing at the same time, consult the various hash prefs to pick a hash algorithm to use. Pass in a 160-bit hint if any of the signing keys are DSA. * keydb.h, pkclist.c (select_algo_from_prefs, algo_available): Pass a "hints" opaque pointer in to let the caller give hints as to what algorithms would be acceptable. The only current hint is for PREFTYPE_HASH to require a 160-bit hash for DSA. Change all callers in encode.c (encode_crypt, encrypt_filter) and sign.c (sign_file). If we settle on MD5 as the best algorithm based solely on recepient keys and SHA1 is also a possibility, use SHA1 unless the user intentionally chose MD5. This is as per 2440:13. * exec.c (make_tempdir): Fix duplicated filename problem. 2002-06-03 David Shaw * packet.h, parse-packet.c (enum_sig_subpkt): Report back from enum_sig_subpkt when a subpacket is critical and change all callers in keylist.c (show_policy_url, show_notation), mainproc.c (print_notation_data), and pkclist.c (do_show_revocation_reason). * keylist.c (show_policy_url, show_notation): Display if the policy or notation is critical. 2002-06-03 David Shaw * main.h, g10.c (main), keylist.c (dump_attribs, set_attrib_fd, list_keyblock_print, list_keyblock_colon), status.h, status.c (get_status_string): New --attribute-fd feature to dump the contents of attribute subpackets for frontends. If --status-fd is also used, then a new status tag ATTRIBUTE is provided for each subpacket. * packet.h, getkey.c (fixup_uidnode, merge_selfsigs_main, merge_selfsigs_subkey), parse-packet.c (setup_user_id): Keep track of the expiration time of a user ID, and while we're at it, use the expired flag from the selfsig rather than reparsing the SIG_EXPIRE subpacket. * photoid.c (generate_photo_id): When adding a new photo ID, showing the photo for confirmation is not safe when noninteractive since the "user" may not be able to dismiss a viewer window. Noted by Timo Schulz. 2002-06-03 David Shaw * options.skel: Sample photo viewers for Win32. * misc.c (pct_expando): Use the seckey for %k/%K if the pubkey is not available. * photoid.h, photoid.c (show_photos): Include the seckey in case a user tries to view a photo on a secret key, and change all callers in keyedit.c (menu_showphoto), keylist.c (list_keyblock_print), and photoid.c (generate_photo_id). 2002-06-02 David Shaw * photoid.c (show_photos): Work properly when not called with a public key. 2002-05-31 David Shaw * sign.c (mk_notation_and_policy): Free unneeded buffer. * hkp.c (parse_hkp_index): Properly handle the '&' character (i.e. "&") in HKP responses. * getkey.c (merge_selfsigs_main): Fix reversed expiration time check with self-sigs. * keyedit.c (sign_uids): When making a new self-sig on a v3 key, make a v3 self-sig unless it is currently a v3 self-sig being promoted to v4. 2002-05-31 Timo Schulz * pkclist.c (do_show_revocation_reason): Don't use capital letters for non-interactive output. (show_revocation_reason): Now it is global. * pubkey-enc.c (get_it): Show if the key has been revoked. 2002-05-30 David Shaw * sign.c (write_signature_packets, sign_file, clearsign_file, sign_symencrypt_file): Make a v4 signature if a policy URL or notation is set, unless v3 sigs are forced via rfc1991 or force-v3-sigs. Also remove some doubled code and clarify an error message (we don't sign in PGP2 mode - just detach-sign). * parse-packet.c (parse_one_sig_subpkt): Add KS_FLAGS to the "any size" section. 2002-05-29 David Shaw * keygen.c (keygen_set_std_prefs, add_feature_mdc): Use "mdc" and "no-mdc" in the prefs string to allow switching on and off the MDC feature. This is needed to properly export a key from GnuPG for use on PGP which does not support MDC - without this, MDC-capable implementations will still try and generate MDCs which will break PGP. * keygen.c (keygen_get_std_prefs): Show "[mdc]" in prefs string if it is enabled. * options.h, g10.c (main), cipher.c (write_header), keygen.c (keygen_set_std_prefs): For consistency, allow the user to specify mdc/no-mdc in the --personal-preference-list. If disabled, it acts just like --disable-mdc. 2002-05-29 David Shaw * options.h, exec.c: Add some debugging info, using the 1024 debug flag. * exec.c (win_system): New system()-like function for win32 that does not return until the child process terminates. Of course, this doesn't help if the process itself exits before it is finished. 2002-05-29 Werner Koch * encode.c (encode_simple): Intialize PKT when --no-literal is used. * keyedit.c (show_key_with_all_names_colon): Renamed the record for revocation keys to "rvk". 2002-05-27 Werner Koch * keyedit.c (show_key_with_all_names_colon): New. (show_key_with_all_names): Divert to new function when required. Sanitize printing of revoker name. 2002-05-27 David Shaw * build-packet.c (build_sig_subpkt): Handle setting sig flags for certain subpacket types (notation, policy url, exportable, revocable). keyedit.c (sign_mk_attrib): Flags no longer need to be set here. * packet.h, parse-packet.c (parse_one_sig_subpkt), build-packet.c (build_sig_subpkt): Call parse_one_sig_subpkt to sanity check buffer lengths before building a sig subpacket. 2002-05-26 David Shaw * sign.c (mk_notation_and_policy): Include secret key to enable %s expandos, and pass notations through pct_expando as well. * main.h, misc.c (pct_expando): Add %s and %S expandos for signer's keyid. 2002-05-25 David Shaw * g10.c (strusage, build_list): Add compress algorithms to --version list. Show algorithm numbers when --verbose --version is done. 2002-05-22 David Shaw * options.h, main.h, keygen.c (keygen_set_set_prefs, keygen_get_std_prefs, keygen_upd_std_prefs), keyedit.c (keyedit_menu), g10.c (main), pkclist.c (select_algo_from_prefs): Add --personal-preference-list which allows the user to factor in their own preferred algorithms when the preference lists are consulted. Obviously, this does not let the user violate a recepient's preferences (and the RFC) - this only influences the ranking of the agreed-on (and available) algorithms from the recepients. Suggested by David Hollenberg. * options.h, keygen.c (keygen_set_std_prefs), g10.c (main): Rename --preference-list to --default-preference-list (as that is what it really is), and make it a true default in that if the user selects "default" they get this list and not the compiled-in list. 2002-05-22 Werner Koch * g10.c (main): Add missing LF in a info printout and made it translatable. Noted by Michael Tokarev. 2002-05-21 Werner Koch * g10.c (main): Removed the undef of USE_SHM_COPROCESSING which was erroneously introduced on 2002-01-09. * signal.c (got_fatal_signal): Don't write the Nul to stderr. Reported by David Hollenberg. 2002-05-18 David Shaw * main.h, g10.c (main), revoke.c (gen_desig_revoke): Generate a designated revocation via --desig-revoke * keyedit.c (keyedit_menu, menu_addrevoker): New "addrevoker" command to add a designated revoker to a key. 2002-05-17 David Shaw * gpgv.c: Add stub for get_ownertrust(). * g10.c (main): --allow-freeform-uid should be implied by OpenPGP. Add --no-allow-freeform-uid. * keyedit.c (sign_uids): Issue a warning when signing a non-selfsigned uid. * getkey.c (merge_selfsigs_main): If a key has no selfsigs, and allow-non-selfsigned-uid is not set, still try and make the key valid by checking all uids for a signature from an ultimately trusted key. 2002-05-16 David Shaw * main.h, keygen.c (keygen_add_revkey): Add revocation key subpackets to a signature (callable by make_keysig_packet). (write_direct_sig): Write a 1F direct key signature. (parse_revocation_key): Parse a string in algo:fpr:sensitive format into a revocation key. (get_parameter_revkey, do_generate_keypair): Call above functions when prompted from a batch key generation file. * build-packet.c (build_sig_subpkt): Allow multiple revocation key subpackets in a single sig. * keydb.h, getkey.c (get_seckey_byfprint): Same as get_pubkey_byfprint, except for secret keys. We only know the fingerprint of a revocation key, so this is needed to retrieve the secret key needed to issue a revokation. * packet.h, parse-packet.c (parse_signature, parse_revkeys): Split revkey parsing off into a new function that can be used to reparse after manipulating the revkey list. * sign.c (make_keysig_packet): Ability to make 1F direct key signatures. 2002-05-15 David Shaw * options.skel: keyserver.pgp.com is gone, so list pgp.surfnet.nl as a sample LDAP server instead. * getkey.c (merge_selfsigs_main): Properly handle multiple revocation keys in a single packet. Properly handle revocation keys that are in out-of-order packets. Remove duplicates in revocation key list. 2002-05-14 Timo Schulz * exec.c (make_tempdir) [MINGW32]: Added missing '\'. 2002-05-14 Stefan Bellon * exec.c (make_tempdir): Make use of EXTSEP_S instead of hardcoded dot as extension separator. 2002-05-13 David Shaw * photoid.c (show_photos): Use the long keyid as the filename for the photo. Use the short keyid as the filename on 8.3 systems. * exec.h, exec.c (make_tempdir, exec_write, exec_finish): Allow caller to specify filename. This should make things easier on windows and macs where the file extension is required, but a whole filename is even better. * keyedit.c (show_key_with_all_names, show_prefs): Show proper prefs for a v4 key uid with no selfsig at all. * misc.c (check_permissions): Don't check permissions on non-normal files (pipes, character devices, etc.) 2002-05-11 Werner Koch * mainproc.c (proc_symkey_enc): Avoid segv in case the parser encountered an invalid packet. * keyserver.c (keyserver_export): Get confirmation before sending all keys. 2002-05-10 Stefan Bellon * g10.c, hkp.c, keyedit.c, keyserver.c: Replaced all occurrances of strcasecmp with ascii_strcasecmp and all occurrances of strncasecmp with ascii_memcasecmp. 2002-05-10 David Shaw * packet.h, getkey.c (fixup_uidnode), keyedit.c (show_prefs): Show assumed prefs for hash and compression as well as the cipher pref. Show assumed prefs if there are no prefs at all on a v4 self-signed key. * options.h, g10.c (main), sign.c (make_keysig_packet): New --cert-digest-algo function to override the default key signing hash algorithm. 2002-05-09 David Shaw * getkey.c (merge_selfsigs_main): Make sure the revocation key list starts clean as this function may be called more than once (e.g. from functions in --edit). * g10.c, encode.c (encode_crypt), sign.c (sign_file, sign_symencrypt_file): Make --compress-algo work like the documentation says. It should be like --cipher-algo and --digest-algo in that it can override the preferences calculation and impose the setting the user wants. No --compress-algo setting allows the usual preferences calculation to take place. * main.h, compress.c (compress_filter): use new DEFAULT_COMPRESS_ALGO define, and add a sanity check for compress algo value. 2002-05-08 David Shaw * pkclist.c (select_algo_from_prefs): There is an assumed compression preference for uncompressed data. 2002-05-07 David Shaw * options.h, g10.c (main), getkey.c (finish_lookup), pkclist.c (algo_available): --pgp7, identical to --pgp6 except that it permits a few algorithms that PGP 7 added: AES128, AES192, AES256, and TWOFISH. Any more of these --pgpX flags, and it'll be time to start looking at a generic --emulate-pgp X option. * export.c (do_export_stream): Warn the user when exporting a secret key if it or any of its secret subkeys are protected with SHA1 while simple_sk_checksum is set. * parse-packet.c (parse_key): Show when the SHA1 protection is used in --list-packets. * options.h, build-packet.c (do_comment), g10.c (main): Rename --no-comment as --sk-comments/--no-sk-comments (--no-comment still works) and make the default be --no-sk-comments. 2002-05-07 Werner Koch * keygen.c (get_parameter_algo): Never allow generation of the deprecated RSA-E or RSA-S flavors of PGP RSA. (ask_algo): Allow generation of RSA sign and encrypt in expert mode. Don't allow ElGamal S+E unless in expert mode. * helptext.c: Added entry keygen.algo.rsa_se. 2002-05-07 David Shaw * keyedit.c (sign_uids): If --expert is set, allow re-signing a uid to promote a v3 self-sig to a v4 one. This essentially deletes the old v3 self-sig and replaces it with a v4 one. * packet.h, parse-packet.c (parse_key), getkey.c (merge_keys_and_selfsig, merge_selfsigs_main): a v3 key with a v4 self-sig must never let the v4 self-sig express a key expiration time that extends beyond the original v3 expiration time. 2002-05-06 David Shaw * keyedit.c (sign_uids): When making a self-signature via "sign" don't ask about sig level or expiration, and include the usual preferences and such for v4 self-sigs. (menu_set_preferences): Convert uids from UTF8 to native before printing. * keyedit.c (sign_uids): Convert uids from UTF8 to native before printing. (menu_set_primary_uid): Show error if the user tries to make a uid with a v3 self-sig primary. 2002-05-05 David Shaw * import.c (import_one): When merging with a key we already have, don't let a key conflict (same keyid but different key) stop the import: just skip the bad key and continue. * exec.c (make_tempdir): Under Win32, don't try environment variables for temp directories - GetTempDir tries environment variables internally, and it's better not to second-guess it in case MS adds some sort of temp dir handling to Windows at some point. 2002-05-05 Timo Schulz * mainproc.c (proc_symkey_enc): Don't ask for a passphrase in the list only mode. 2002-05-05 David Shaw * keyserver.c (keyserver_refresh): --refresh-keys implies --merge-only so as not to import keys with keyids that match the ones being refreshed. Noted by Florian Weimer. 2002-05-04 Stefan Bellon * free-packet.c (copy_public_key): Don't call m_alloc(0), therefore added consistency check for revkey and numrefkeys. * getkey.c (check_revocation_keys): Added consistency check for revkey and numrefkeys. * keyedit.c (show_key_with_all_names): Likewise. 2002-05-03 David Shaw * photoid.c: Provide default image viewer for Win32. * misc.c (pct_expando): %t means extension, not name ("jpg", not "jpeg"). * keyserver.c (keyserver_spawn), photoid.c (show_photos), exec.h, exec.c: Allow the caller to determine the temp file extension when starting an exec_write and change all callers. * keyedit.c (sign_uids): Nonrevocable key signatures cause an automatic promotion to v4. * exec.c: Provide stubs for exec_ functions when NO_EXEC is defined. 2002-05-02 David Shaw * photoid.h, photoid.c (parse_image_header, image_type_to_string): Useful functions to return data about an image. * packet.h, parse-packet.c (make_attribute_uidname, parse_attribute_subpkts, parse_attribute), photoid.h, photoid.c (show_photos): Handle multiple images in a single attribute packet. * main.h, misc.c (pct_expando), sign.c (mk_notation_and_policy), photoid.c (show_photos): Simpler expando code that does not require using compile-time string sizes. Call image_type_to_string to get image strings (i.e. "jpg", "image/jpeg"). Change all callers. * keyedit.c (menu_showphoto), keylist.c (list_keyblock_print): Allow viewing multiple images within a single attribute packet. * gpgv.c: Various stubs for link happiness. 2002-05-02 David Shaw * build-packet.c (build_sig_subpkt), keyedit.c (sign_uids), options.h, sign.c (mk_notation_and_policy), g10.c (main, add_notation_data, add_policy_url (new), check_policy_url (removed)): Allow multiple policy URLs on a given signature. Split "--notation-data" into "--cert-notation" and "--sig-notation" so the user can set different policies for key and data signing. For backwards compatibility, "--notation-data" sets both, as before. 2002-05-02 Werner Koch * options.skel: Removed the comment on trusted-keys because this option is now deprecated. 2002-05-01 David Shaw * keyedit.c (menu_adduid): 2440bis04 says that multiple attribute packets on a given key are legal. * keyserver.c (keyserver_refresh): the fake v3 keyid hack applies to "mailto" URLs as well since they are also served by pksd. 2002-04-29 Werner Koch Added a copyright year for files changed this year. 2002-04-25 Werner Koch * g10.c, options.h: New options --display, --ttyname, --ttytype, --lc-ctype, --lc-messages to be used with future versions of the gpg-agent. * passphrase.c (agent_send_option,agent_send_all_options): New. (agent_open): Send options to the agent. * trustdb.c (update_ownertrust, clear_ownertrust): Do an explicit do_sync because revalidation_mark does it only if when the timestamp actually changes. 2002-04-23 David Shaw * main.h, keygen.c (do_generate_keypair), keylist.c (print_signature_stats, list_all, list_one, list_keyblock, list_keyblock_print, list_keyblock_colon): After generating a new key, show the key information (name, keyid, fingerprint, etc.) Also do not print uncheckable signatures (missing key..) in --check-sigs. Print statistics (N missing keys, etc.) after --check-sigs. * keyedit.c (sign_uids): When signing a key with an expiration date on it, the "Do you want your signature to expire at the same time?" question should default to YES. 2002-04-22 David Shaw * parse-packet.c (parse_plaintext), packet.h, plaintext.c (handle_plaintext): Fix bug in handling literal packets with zero-length data (no data was being confused with partial body length). * misc.c (pct_expando), options.skel: %t means extension ("jpg"). %T means MIME type ("image/jpeg"). * import.c (import_one): Only trigger trust update if the keyring is actually changed. * export.c (do_export_stream): Missing a m_free. 2002-04-22 Stefan Bellon * keyid.c (expirestr_from_sk, expirestr_from_sig): Added _() to string constant. * exec.c (make_tempdir) [__riscos__]: Better placement of temporary file. 2002-04-20 David Shaw * keygen.c (generate_subkeypair): 2440bis04 adds that creating subkeys on v3 keys is a MUST NOT. * getkey.c (finish_lookup): The --pgp6 "use the primary key" behavior should only apply while data signing and not encryption. Noted by Roger Sondermann. 2002-04-19 Werner Koch * keygen.c (keygen_set_std_prefs): Put back 3DES because the RFC says it is good form to do so. 2002-04-19 David Shaw * keyedit.c (menu_deluid): Only cause a trust update if we delete a non-revoked user id. * hkp.c (hkp_ask_import), keyserver.c (parse_keyserver_options, keyserver_spawn), options.h: Remove fast-import keyserver option (no longer meaningful). * g10.c (main), keyedit.c (sign_uids), options.h: Change --default-check-level to --default-cert-check-level as it makes clear what it operates on. * g10.c (main): --pgp6 also implies --no-ask-sig-expire. * delkey.c (do_delete_key): Comment. * keyedit.c (sign_uids, keyedit_menu, menu_deluid, menu_delsig, menu_expire, menu_revsig, menu_revkey): Only force a trustdb check if we did something that changes it. * g10.c: add "--auto-check-trustdb" to override a "--no-auto-check-trustdb" 2002-04-19 Werner Koch * tdbio.c (tdbio_write_nextcheck): Return a status whether the stamp was actually changed. * trustdb.c (revalidation_mark): Sync the changes. Removed the sync operation done by its callers. (get_validity): Add logic for maintaining a pending_check flag. (clear_ownertrust): New. * keyedit.c (sign_uids): Don't call revalidation_mark depending on primary_pk. (keyedit_menu): Call revalidation_mark after "trust". (show_key_with_all_names): Print a warning on the wrong listed key validity. * delkey.c (do_delete_key): Clear the owenertrust information when deleting a public key. 2002-04-18 Werner Koch * seskey.c (encode_md_value): Print an error message if a wrong digest algorithm is used with DSA. Changed all callers to cope with a NULL return. Problem noted by Imad R. Faiad. 2002-04-18 David Shaw * trustdb.c (mark_usable_uid_certs): Properly handle nonrevocable signatures that can expire. In short, the only thing that can override an unexpired nonrevocable signature is another unexpired nonrevocable signature. * getkey.c (finish_lookup): Always use primary signing key for signatures when --pgp6 is on since pgp6 and 7 do not understand signatures made by signing subkeys. 2002-04-18 Werner Koch * trustdb.c (validate_keys): Never schedule a nextcheck into the past. (validate_key_list): New arg curtime use it to set next_expire. (validate_one_keyblock): Take the current time from the caller. (clear_validity, reset_unconnected_keys): New. (validate_keys): Reset all unconnected keys. * getkey.c (premerge_public_with_secret): Fixed 0x12345678! syntax for use with secret keys. (lookup): Advance the searchmode after a search FIRST. * seckey-cert.c (do_check): Always calculate the old checksum for use after unprotection. * g10.c, options.skel: New option --no-escape-from. Made --escape-from and --force-v3-sigs the default and removed them from the options skeleton. 2002-04-16 Werner Koch * parse-packet.c (parse_key): Support a SHA1 checksum as per draft-rfc2440-bis04. * packet.h (PKT_secret_key): Add field sha1chk. * seckey-cert.c (do_check): Check the SHA1 checksum (protect_secret_key): And create it. * build-packet.c (do_secret_key): Mark it as sha-1 protected. * g10.c, options.h: New option --simple-sk-checksum. 2002-04-13 David Shaw * parse-packet.c (parse_signature): Minor fix - signatures should expire at their expiration time and not one second later. * keygen.c (proc_parameter_file): Allow specifying preferences string (i.e. "s5 s2 z1 z2", etc) in a batchmode key generation file. * keyedit.c (keyedit_menu): Print standard error message when signing a revoked key (no new translation). * getkey.c (merge_selfsigs): Get the default set of key prefs from the real (not attribute) primary uid. 2002-04-12 David Shaw * pkclist.c (build_pk_list): Fix bug that allowed a key to be selected twice in batch mode if one instance was the default recipient and the other was an encrypt-to. Noted by Stefan Bellon. * parse-packet.c (dump_sig_subpkt): Show data in trust and regexp sig subpackets. * keyedit.c (keyedit_menu): Use new function real_uids_left to prevent deleting the last real (i.e. non-attribute) uid. Again, according to the attribute draft. (menu_showphoto): Make another string translatable. 2002-04-11 David Shaw * build-packet.c (build_sig_subpkt): Delete subpackets from both hashed and unhashed area on update. (find_subpkt): No longer needed. * keyedit.c (sign_uids): With --pgp2 on, refuse to sign a v3 key with a v4 signature. As usual, --expert overrides. Try to tweak some strings to a closer match so they can all be translated in one place. Use different helptext keys to allow different help text for different questions. * keygen.c (keygen_upd_std_prefs): Remove preferences from both hashed and unhashed areas if they are not going to be used. 2002-04-10 David Shaw * misc.c (pct_expando), options.skel: Use %t to indicate type of a photo ID (in this version, it's always "jpeg"). Also tweak string expansion loop to minimize reallocs. * mainproc.c (do_check_sig): Variable type fix. * keyedit.c (menu_set_primary_uid): Differentiate between true user IDs and attribute user IDs when making one of them primary. That is, if we are making a user ID primary, we alter user IDs. If we are making an attribute packet primary, we alter attribute packets. This matches the language in the latest attribute packet draft. * keyedit.c (sign_uids): No need for the empty string hack. * getkey.c (fixup_uidnode): Only accept preferences from the hashed segment of the self-sig. 2002-04-10 Werner Koch * tdbio.c (migrate_from_v2): Fixed the offset to read the old ownertrust value and only add entries to the table if we really have a value. 2002-04-08 David Shaw * status.h, status.c (get_status_string): Add KEYEXPIRED, EXPSIG, and EXPKEYSIG. Add "deprecated-use-keyexpired-instead" to SIGEXPIRED. * sig-check.c (do_check): Start transition from SIGEXPIRED to KEYEXPIRED, since the actual event is signature verification by an expired key and not an expired signature. (do_signature_check, packet.h): Rename as signature_check2, make public, and change all callers. * mainproc.c (check_sig_and_print, do_check_sig): Use status EXPSIG for an expired, but good, signature. Add the expiration time (or 0) to the VALIDSIG status line. Use status KEYEXPSIG for a good signature from an expired key. * g10.c (main): remove checks for no arguments now that argparse does it. 2002-04-06 Werner Koch * keyring.c (keyring_get_keyblock): Disable the keylist mode here. * encode.c (encode_simple, encode_crypt): Only test on compressed files if a compress level was not explicity set. * keygen.c (keygen_set_std_prefs): Removed Blowfish and Twofish from the list of default preferences, swapped the preferences of RMD160 and SHA1. Don't include a preference to 3DES unless the IDEA kludge gets used. * free-packet.c (free_packet): call free_encrypted also for PKT_ENCRYPTED_MDC. * compress.c (release_context): New. (handle_compressed): Allocate the context and setup a closure to release the context. This is required because there is no guarantee that the filter gets popped from the chain at the end of the function. Problem noted by Timo and probably also the cause for a couple of other reports. (compress_filter): Use the release function if set. * tdbio.c [__CYGWIN32__]: Don't rename ftruncate. Noted by Disastry. * parse-packet.c (parse_signature): Put parens around a bit test. * exec.c (make_tempdir): Double backslash for TMP directory creation under Windows. Better strlen the DIRSEP_S constants for allocation measurements. * decrypt.c (decrypt_messages): Release the passphrase aquired by get_last_passphrase. 2002-04-02 Werner Koch * Makefile.am (EXTRA_DIST): Removed OPTIONS an pubring.asc - they are no longer of any use. 2002-04-03 David Shaw * keyserver.c (parse_keyserver_options): fix auto-key-retrieve to actually work as a keyserver-option (noted by Roger Sondermann). * keylist.c (reorder_keyblock): do not reorder the primary attribute packet - the first user ID must be a genuine one. 2002-03-31 David Shaw * keylist.c (list_keyblock_colon): Fix ownertrust display with --with-colons. * keygen.c (generate_user_id), photoid.c (generate_photo_id): Properly initialize the user ID refcount. A few more "y/n" -> "y/N" in photoid.c. * keyedit.c (ask_revoke_sig): Warn the user if they are about to revoke an expired sig (not a problem, but they should know). Also tweak a few prompts to change "y/n" to "y/N", which is how most other prompts are written. * keyserver.c (keyserver_search_prompt): Control-d escapes the keyserver search prompt. * pkclist.c (show_revocation_reason & callers): If a subkey is considered revoked solely because the parent key is revoked, print the revocation reason from the parent key. * trustdb.c (get_validity): Allow revocation/expiration to apply to a uid/key with no entry in the trustdb. 2002-03-29 David Shaw * keyserver.c (printunquoted): unquote backslashes from keyserver searches * hkp.c (write_quoted): quote backslashes from keyserver searches 2002-03-26 Werner Koch * keygen.c (ask_keysize): Removed the warning for key sizes > 1536. 2002-03-25 Werner Koch * keyedit.c (sign_uids): Use 2 strings and not a %s so that translations can be done the right way. * helptext.c: Fixed small typo. 2002-03-23 David Shaw * import.c (append_uid, merge_sigs): it is okay to import completely non-signed uids now (with --allow-non-selfsigned-uid). * getkey.c (get_primary_uid, merge_selfsigs_main): do not choose an attribute packet (i.e. photo) as primary uid. This prevents oddities like "Good signature from [image of size 2671]". This is still not perfect (one can still select an attribute packet as primary in --edit), but is closer to the way the draft is going. * g10.c (build_list): algorithms should include 110. * g10.c (main): --pgp2 implies --no-ask-sig-expire and --no-ask-cert-expire as those would cause a v4 sig/cert. * armor.c (is_armor_header): be more lenient in what constitutes a valid armor header (i.e. -----BEGIN blah blah-----) as some Windows programs seem to add spaces at the end. --openpgp makes it strict again. 2002-03-18 David Shaw * keyserver.c (keyserver_search_prompt): Properly handle a "no keys found" case from the internal HKP code (external HKP is ok). Also, make a COUNT -1 (i.e. streamed) keyserver response a little more efficient. * g10.c (main): Add --no-allow-non-selfsigned-uid 2002-03-17 David Shaw * g10.c (main): --openpgp implies --allow-non-selfsigned-uid. * getkey.c (merge_selfsigs_main): If none of the uids are primary (because none are valid) then pick the first to be primary (but still invalid). This is for cosmetics in case some display needs to print a user ID from a non-selfsigned key. Also use --allow-non-selfsigned-uid to make such a key valid and not --always-trust. The key is *not* automatically trusted via --allow-non-selfsigned-uid. * mainproc.c (check_sig_and_print): Make sure non-selfsigned uids print [uncertain] on verification even though one is primary now. * getkey.c (merge_selfsigs): If the main key is not valid, then neither are the subkeys. * import.c (import_one): Allow --allow-non-selfsigned-uid to work on completely unsigned keys. Print the uids in UTF8. Remove mark_non_selfsigned_uids_valid(). * keyedit.c (show_key_with_all_names): Show revocation key as UTF8. * sign.c (clearsign_file): Allow --not-dash-escaped to work with v3 keys. 2002-03-14 Werner Koch * main.h: Changed the default algorithms to CAST5 and SHA1. 2002-03-13 David Shaw * import.c (chk_self_sigs): Show which user ID a bad self-sig (invald sig or unsupported public key algorithm) resides on. * import.c (chk_self_sigs): any valid self-sig should mark a user ID or subkey as valid - otherwise, an attacker could DoS the user by inventing a bogus invalid self-signature. 2002-03-07 David Shaw * g10.c (main): make a few more strings translatable. * options.h, options.skel, g10.c (main), gpgv.c, mainproc.c (check_sig_and_print), keyserver.c (parse_keyserver_options): --auto-key-retrieve should really be a keyserver-option variable. * import.c (revocation_present): new function to print a warning if a key is imported that has been revoked by designated revoker, but the designated revoker is not present to verify the revocation. If keyserver-options auto-key-retrieve is set, try and fetch the designated revoker from the keyserver. * import.c (import_one): call revocation_present after importing a new key. Note that this applies to --import, --recv-keys, and --search-keys. * keyserver-internal.h, keyserver.c (keyserver_import_fprint): import via fingerprint (for revocation keys). * keyserver.c (keyserver_import_keyid): much simpler implementation now that we're using KEYDB_SEARCH_DESC internally. 2002-03-04 David Shaw * revoke.c (gen_revoke): do not prompt for revocation reason for v3 revocations (unless force-v4-certs is on) since they wouldn't be used anyway. * keyedit.c (menu_revsig): show the status of the sigs (exportable? revocable?) to the user before prompting for which sig to revoke. Also, make sure that local signatures get local revocations. * keyedit.c (ask_revoke_sig): remind the user which sigs are local. * g10.c (main): Add "exec-path" variable to override PATH for execing programs. * export.c (do_export_stream): properly check return code from classify_user_id to catch unclassifiable keys. 2002-03-03 David Shaw * parse-packet.c (parse_signature): variable type tweak for RISC OS (from Stefan) 2002-02-28 David Shaw * getkey.c (check_revocation_keys): New function to check a revocation against a list of potential revocation keys. Note the loop-breaking code here. This is to prevent blowing up if A is B's revocation key, while B is also A's. Note also that this is written so that a revoked revoker can still issue revocations: i.e. If A revokes B, but A is revoked, B is still revoked. I'm not completely convinced this is the proper behavior, but it matches how PGP does it. It does at least have the advantage of much simpler code - my first version of this had lots of loop maintaining code so you could chain revokers many levels deep and if D was revoked, C was not, which meant that B was, and so on. It was sort of scary, actually. * getkey.c (merge_selfsigs_main): Add any revocation keys onto the pk. This is particularly interesting since we normally only get data from the most recent 1F signature, but you need multiple 1F sigs to properly handle revocation keys (PGP does it this way, and a revocation key could be marked "sensitive" and hence in a different signature). Also, if a pk has a revocation key set, check for revocation sigs that were not made by us - if made by a valid revocation key, mark the pk revoked. * packet.h, getkey.c (cache_public_key): do not cache key if "dont_cache" is set. This allows the revocation key code to look up a key and return information that may be inaccurate to prevent loops without caching the fake data. * packet.h, sig-check.c (do_signature_check): Record if a signature was made by a revoked pk. * packet.h, parse-packet.c (parse_one_sig_subpkt, can_handle_critical, parse_signature): Get revocation key information out of direct sigs. * keylist.c (list_keyblock_print): don't assume that the presence of a 0x20 signature means the key is revoked. With revocation keys, this may not be true if the revocation key is not around to verify it or if verification failed. Also, 0x1F should get listed as "sig", and not "unexpected signature class". * keyedit.c (show_key_with_all_names): Add a flag for printing revoker information and change all callers. * import.c (merge_blocks): merge in any new direct key (0x1F) sigs. * import.c (import_revoke_cert): don't keep processing after a revocation is rejected. * import.c (delete_inv_parts): Allow importing a revocation signature even if it was not issued by the key. This allows a revocation key to issue it. Of course, the sig still needs to be checked before we trust it. * free-packet.c (copy_public_key): Include a new copy of the revocation keys when duping a pk. * free-packet.c (free_seckey_enc, release_public_key_parts): Free any revocation keys that are attached to a sig or pk. * export.c (do_export_stream): Do not export signatures with "sensitive" revocation keys in them. 2002-02-27 David Shaw * export.c (do_export_stream): Do not include v3 keys in a --export-secret-subkeys export. * getkey.c (merge_selfsigs_main): If a key isn't valid (say, because of no self-signature), allow --always-trust to force it valid so it can be trusted. 2002-02-25 David Shaw * hkp.c (hkp_ask_import), hkp.h, keyserver.c (all): treat key lists internally as fingerprints when possible. All this is via KEYDB_SEARCH_DESC - no point in reinventing the wheel. This allows the helper program to search the keyserver by fingerprint if desired (and the keyserver supports it). Note that automatic fingerprint promotion during refresh only applies to v4 keys as a v4 fingerprint can be easily changed into a long or short key id, and a v3 cannot. * pubkey-enc.c, getkey.c, misc.c, main.h: Take two copies of hextobyte() from pubkey-enc.c and getkey.c and make them into one copy in misc.c. 2002-02-22 David Shaw * keyserver.c (keyserver_search_prompt): Detect a "no keys found" case even if the helper program does not explicitly say how many keys were found. * hkp.c (parse_hkp_index): Bug fix - don't report non-revoked keys as revoked in HKP key searches. 2002-02-19 Werner Koch * parse-packet.c (parse_trust): Made parsing more robust. 2002-02-19 David Shaw * hkp.c (parse_hkp_index): Catch corruption in HKP index lines (can be caused by broken or malicious keyservers). * keyserver.c (keyserver_work): Add KEYSERVER_NOT_SUPPORTED for unsupported actions (say, a keyserver that has no way to search, or a readonly keyserver that has no way to add). Also add a USE_EXTERNAL_HKP define to disable the internal HKP keyserver code. 2002-02-14 Werner Koch * g10.c: New option --no-use-agent. * pkclist.c (check_signatures_trust): Always print the warning for unknown and undefined trust. Removed the did_add cruft. Reported by Janusz A. Urbanowicz. 2002-02-11 David Shaw * hkp.c (parse_hkp_index): Bug fix - properly handle user IDs with colons (":") in them while HKP searching. 2002-02-09 David Shaw * misc.c (pct_expando): More comments. * keydb.h, sign.c (mk_notation_and_policy): Clarify what is a sig and what is a cert. A sig has sigclass 0x00, 0x01, 0x02, or 0x40, and everything else is a cert. * g10.c (main), keyedit.c (keyedit_menu): Add a "nrlsign" for nonrevocable and local key signatures. * g10.c (main): Add a --no-force-mdc to undo --force-mdc. * options.h, g10.c (main), cipher.c (write_header): Add a knob to --disable-mdc/--no-disable-mdc. Off by default, of course, but is used in --pgp2 and --pgp6 modes. * pkclist.c (build_pk_list): Allow specifying multiple users in the "Enter the user ID" loop. Enter a blank line to stop. Show each key+id as it is added. * keylist.c (show_policy_url), mainproc.c (print_notation_data): It is not illegal (though possibly silly) to have multiple policy URLs in a given signature, so print all that are present. * hkp.c (hkp_search): More efficient implementation of URL-ifying code. 2002-02-04 David Shaw * main.h, misc.c (pct_expando): New function to generalize %-expando processing in any arbitrary string. * photoid.c (show_photo): Call the new pct_expando function rather than expand strings internally. * sign.c (mk_notation_and_policy): Show policy URLs and notations when making a signature if show-policy/show-notation is on. %-expand policy URLs during generation. This lets the user have policy URLs of the form "http://notary.jabberwocky.com/keysign/%K" which will generate a per-signature policy URL. * main.h, keylist.c (show_policy_url, show_notation): Add amount to indent so the same function can be used in key listings as well as during sig generation. Change all callers. 2002-02-04 David Shaw * keyserver.c, options.h (parse_keyserver_options, keyidlist): Workaround for the pksd and OKS keyserver bug that calculates v4 RSA keyids as if they were v3. The workaround/hack is to fetch both the v4 (e.g. 99242560) and v3 (e.g. 68FDDBC7) keyids. This only happens for key refresh while using the HKP scheme and the refresh-add-fake-v3-keyids keyserver option must be set. This should stay off by default. 2002-02-03 David Shaw * keyserver.c (keyserver_spawn): Bug fix - do not append keys to each other when --sending more than one. 2002-02-02 David Shaw * options.h, g10.c (main), keyedit.c (sign_uids), sign.c (mk_notation_and_policy): Split "--set-policy-url" into "--cert-policy-url" and "--sig-policy-url" so the user can set different policies for key and data signing. For backwards compatibility, "--set-policy-url" sets both, as before. 2002-01-30 Werner Koch * g10.c (main): --gen-random --armor does now output a base64 encoded string. 2002-01-28 David Shaw * g10.c (main), options.h, pkclist.c (algo_available): --pgp6 flag. This is not nearly as involved as --pgp2. In short, it turns off force_mdc, turns on no_comment, escape_from, and force_v3_sigs, and sets compression to 1. It also restricts the user to IDEA (if present), 3DES, CAST5, MD5, SHA1, and RIPEMD160. See the comments above algo_available() for lots of discussion on why you would want to do this. 2002-01-27 David Shaw * keygen.c (keygen_set_std_prefs): Comment * keyedit.c (sign_uids): Bug fix - when signing with multiple secret keys at the same time, make sure each key gets the sigclass prompt. * exec.c (exec_finish): Close the iobuf and FILE before trying to waitpid, so the remote process will get a SIGPIPE and exit. This is only a factor when using a pipe to communicate. * exec.c (exec_write): Disable cache-on-close of the fd iobuf (is this right? Why is a fd iobuf cached at all?) 2002-01-26 Werner Koch * g10.c, options.h: New option --gpg-agent-info * passphrase.c (agent_open): Let it override the environment info. * seckey-cert.c (check_secret_key): Always try 3 times when the agent is enabled. * options.skel: Describe --use-agent. 2002-01-24 David Shaw * pubkey-enc.c (is_algo_in_prefs, get_it): Only check preferences against keys with v4 self sigs - there is really little point in warning for every single non-IDEA message encrypted to an old key. * pkclist.c (select_algo_from_prefs): Only put in the fake IDEA preference if --pgp2 is on. * mainproc.c (check_sig_and_print): Print "Expired" for expired but good signatures (this still prints "BAD" for expired but bad signatures). 2002-01-23 David Shaw * keygen.c (ask_keysize): Cosmetic: don't present a RSA signing key as a "keypair" which can be 768 bits long (as RSA minimum is 1024). * pubkey-enc.c (is_algo_in_prefs): Allow IDEA as a fake preference for v3 keys with v3 selfsigs. 2002-01-22 David Shaw * packet.h, getkey.c (merge_selfsigs_main), pkclist.c (select_algo_from_prefs): Implement the fake IDEA preference as per RFC2440:12.1. This doesn't mean that IDEA will be used (the plugin may not be present), but it does mean that a v3 key with a v3 selfsig has an implicit IDEA preference instead of 3DES. v3 keys with v4 selfsigs use preferences as normal. * encode.c (encode_crypt): if select_algo_from_prefs fails, this means that we could not find a cipher that both keys like. Since all v4 keys have an implicit 3DES preference, this means there is a v3 key with a v3 selfsig in the list. Use 3DES in this case as it is the safest option (we know the v4 key can handle it, and we'll just hope the v3 key is being used in an implementation that can handle it). If --pgp2 is on, warn the user what we're doing since it'll probably break PGP2 compatibility. * g10.c (main): Do not force using IDEA for encrypted files in --pgp2 mode - let the fake IDEA preference choose this for us for better compatibility when encrypting to multiple keys, only some of which are v3. * keygen.c (keygen_set_std_prefs): Put 3DES on the end of the default cipher pref list (RFC2440: "...it is good form to place it there explicitly."). If the user has the IDEA plugin installed, put a preference for IDEA *after* 3DES to effectively disable its use for everything except encrypting along with v3 keys. * encode.c, g10.c, sign.c: Change the PGP2 warning line from "... will not be usable ..." to "... may not be usable ..." as the user could be using one of the enhanced PGP2 variations. * helptext.c: Revise the sign_uid.class help text as suggested by Stefan. 2002-01-20 Werner Koch * passphrase.c (passphrase_to_dek): Add tryagain_text arg to be used with the agent. Changed all callers. (agent_get_passphrase): Likewise and send it to the agent * seckey-cert.c (do_check): New arg tryagain_text. (check_secret_key): Pass the string to do_check. * keygen.c (ask_passphrase): Set the error text is required. * keyedit.c (change_passphrase): Ditto. * passphrase.c (agent_open): Disable opt.use_agent in case of a problem with the agent. (agent_get_passphrase): Ditto. (passphrase_clear_cache): Ditto. 2002-01-19 Werner Koch * passphrase.c (agent_open): Add support for the new Assuan based gpg-agent. New arg to return the used protocol version. (agent_get_passphrase): Implemented new protocol here. (passphrase_clear_cache): Ditto. (readline): New. 2002-01-15 Timo Schulz * encode.c (encode_crypt_files): Fail if --output is used. * g10.c: New command --decrypt-files. * decrypt.c (decrypt_messages): New. 2002-01-09 David Shaw * g10.c, misc.c, gpgv.c: move idea_cipher_warn to misc.c so gpgv.c doesn't need a stub for it any longer. * g10.c (get_temp_dir), main.h: no longer used (it's in exec.c now) * g10.c (main), delkey.c (delete_keys), main.h : Allow --delete-key (now --delete-keys, though --delete-key still works, of course) to delete multiple keys in one go. This applies to --delete-secret-key(s) and --delete-secret-and-public-key(s) as well. 2002-01-09 Timo Schulz * encode.c (encode_crypt_files): Now it behaves like verify_files. * g10.c (main): We don't need to check argc for encode_crypt_files any longer. 2002-01-09 Timo Schulz * exec.c: Include windows.h for dosish systems. 2002-01-08 Timo Schulz * g10.c (main): New description for --encrypt-files. 2002-01-08 Werner Koch * g10.c (main): Must register the secring for encryption because it is needed to figure out the default recipient. Reported by Roger Sondermann. 2002-01-05 David Shaw * keyedit.c (menu_adduid): Require --expert before adding a photo ID to a v3 key, and before adding a second photo ID to any key. * keyedit.c (keyedit_menu): Don't allow adding photo IDs in rfc1991 or pgp2 mode. * getkey.c (merge_selfsigs_subkey): Permit v3 subkeys. Believe it or not, this is allowed by rfc 2440, and both PGP 6 and PGP 7 work fine with them. * g10.c, options.h, keyedit.c, sign.c: Move the "ask for expiration" switch off of --expert, which was getting quite overloaded, and onto ask-sig-expire and ask-cert-expire. Both default to off. * g10.c (main): Change the default compression algo to 1, to be more OpenPGP compliant (PGP also uses this, so it'll help with interoperability problems as well). * encode.c (encode_crypt): Handle compression algo 2, since the default is now 1. * build-packet.c (build_attribute_subpkt): Fix off-by-one error. 2002-01-05 Werner Koch * g10.c (main): Do not register the secret keyrings for certain commands. * keydb.c (keydb_add_resource): Use access to test for keyring existence. This avoids cached opened files which are bad under RISC OS. 2002-01-04 David Shaw * sign.c (sign_file, sign_symencrypt_file): always use one-pass packets unless rfc1991 is enabled. This allows a signature made with a v3 key to work in PGP 6 and 7. Signatures made with v4 keys are unchanged. * g10.c (main): Disallow non-detached signatures in PGP2 mode. Move the "you must use files and not pipes" PGP2 warning up so all the PGP2 stuff is together. * encode.c (encode_simple): Use the actual filesize instead of partial length packets in the internal literal packet from a symmetric message. This breaks PGP5(?), but fixes PGP2, 6, and 7. It's a decent tradeoff. Note there was only an issue with old-style RFC1991 symmetric messages. 2440-style messages in 6 and 7 work with or without partial length packets. 2002-01-03 David Shaw * g10.c (main): Removed --no-default-check-level option, as it is not consistent with other "default" options. Plus, it is the same as saying --default-check-level 0. * exec.c (exec_read): Disallow caching tempfile from child process, as this keeps the file handle open and can cause unlink problems on some platforms. * keyserver.c (keyserver_search_prompt): Minor tweak - don't bother to transform keyids into textual form if they're just going to be transformed back to numbers. 2002-01-03 Timo Schulz * g10.c: New command --encrypt-files. * verify.c (print_file_status): Removed the static because encode_crypt_files also uses this function. * main.h (print_files_status): New. (encode_crypt_files): New. * encode.c (encode_crypt_files): New. 2002-01-02 Stefan Bellon * keyserver.c: Moved util.h include down in order to avoid redefinition problems on RISC OS. * keyring.c (keyring_lock): Only lock keyrings that are writable. * keyring.c (keyring_update_keyblock): Close unused iobuf. * hkp.c (parse_hkp_index, hkp_search) [__riscos__]: Changed unsigned char* to char* because of compiler issues. * exec.c (exec_finish) [__riscos__]: Invalidate close cache so that file can be unlinked. 2001-12-28 David Shaw * g10.c (main): Use a different strlist to check extensions since they need to be handled seperately now. * misc.c,main.h (check_permissions): Properly handle permission and ownership checks on files in the lib directory (e.g. /usr/local/lib/gnupg), which are owned by root and are world-readable, and change all callers to specify extension or per-user file. * photoid.c (show_photo), keyserver.c (keyserver_spawn): Bug fix - don't call exec_finish if exec_write fails. * keyserver.c (keyserver_spawn): Look for OPTIONS from the keyserver helper - specifically, a "OUTOFBAND" option for the email keyserver. * mainproc.c (list_node), keylist.c (list_keyblock_colon), import.c (delete_inv_parts), export.c (do_export_stream): Use signature flags for exportability check rather than re-parsing the subpacket. * keyid.c, keydb.h (get_lsign_letter): No longer needed. 2001-12-27 David Shaw * exec.c (exec_finish): Show errors when temp files cannot be deleted for whatever reason. * exec.c (exec_read): Don't rely on WEXITSTATUS being present. * exec.c (make_tempdir): Add temp file creator for win32. Don't create an incoming temp file if the exec is write-only. * keyserver.c (keyserver_spawn): Clean up error handling, for when the spawn fails. * photoid.c (show_photo): Clean up error handling. * misc.c (check_permissions): Neaten. 2001-12-25 David Shaw * mkdtemp.c (mkdtemp): Add copyleft info and tweak the 'X' counter to be a bit simpler. * keyserver.c, photoid.c: Remove unused headers left over from when the exec functions lived there. 2001-12-23 Timo Schulz * misc.c (check_permissions): Do not use it for W32 systems. * tdbio.c (migrate_from_v2): Define ftruncate as chsize() for W32. * mkdtemp.c: W32 support. * photoid.c: Ditto. * exec.c: Ditto. 2001-12-22 David Shaw * exec.c (make_tempdir): avoid compiler warning with const * mkdtemp.c (mkdtemp): catch the empty ("") string case in case someone repurposes mkdtemp at some point. * photoid.c (generate_photo_id, show_photo): some type changes from Stefan Bellon. * exec.c (make_tempdir): handle Win32 systems, suggested by Timo Schulz. 2001-12-22 Werner Koch * encode.c (encode_simple, encode_crypt): i18n 2 strings. 2001-12-22 Timo Schulz * encode.c (encode_simple, encode_crypt): Use is_file_compressed to avoid to compress compressed files. 2001-12-22 Werner Koch * keyserver.c (keyserver_spawn): Removed some variables declaration due to shadowing warnings. * build-packet.c (build_attribute_subpkt): s/index/idx/ to avoid compiler warnig due to index(3). * getkey.c (get_ctx_handle): Use KEYDB_HANDLE as return value. * keylist.c (list_one): Made resname const. * keyedit.c (keyedit_menu): Allow "addphoto" only when --openpgp is not used. * options.skel: Changed one example photo viewer to qiv. 2001-12-21 David Shaw * Makefile.am: add exec.c, exec.h, photoid.c, and photoid.h * build-packet.c (build_attribute_subpkt): new function to build the raw attribute subpacket. Note that attribute subpackets have the same format as signature subpackets. * exec.c: new file with generic exec-a-program functionality. Used by both photo IDs and keyserver helpers. This is pretty much the same code that used to be keyserver specific, with some changes to be usable generically. * free-packet.c (free_attributes (new)): function to free an attribute packet. * gpgv.c: added stub show_photo * keyedit.c (keyedit_menu, menu_adduid, menu_showphoto): can add a photo (calls generate_photo_id), or display a photo (calls show_photo) from the --edit menu. New commands are "addphoto", and "delphoto" (same as "deluid"). * keylist.c (list_keyblock_print): show photos during key list if --show-photos enabled. * keyserver.c (keyserver_spawn): use the generic exec_xxx functions to call keyserver helper. * g10.c, options.h: three new options - --{no-}show-photos, and --photo-viewer to give the command line to display a picture. * options.skel: instructions for the photo viewer * parse-packet.c (parse_user_id, setup_user_id (new)): common code for both user IDs and attribute IDs moved to setup_user_id. * parse-packet.c (make_attribute_uidname (new)): constructs a fake "name" for attribute packets (e.g. "[image of size ...]") * parse-packet.c (parse_attribute (replaces parse_photo_id), parse_attribute_subpkts): Builds an array of individual attributes. Currently only handles attribute image / type jpeg subpackets. * sign.c (hash_uid): Fix bug in signing attribute (formerly photo_id) packets. * packet.h, and callers: globally change "photo_id" to "attribute" and add structures for attributes. The packet format is generic attributes, even though the only attribute type thus far defined is jpeg. 2001-12-21 David Shaw * parse-packet.c (can_handle_critical): Can handle critical revocation subpackets now. * trustdb.c (mark_usable_uid_certs): Disregard revocations for nonrevocable sigs. Note that this allows a newer revocable signature to override an older nonrevocable signature. * sign.c (make_keysig_packet): add a duration field and change all callers. This makes make_keysig_packet closer to write_signature_packets and removes some duplicated expiration code. * keyedit.c (keyedit_menu, menu_revsig, sign_uids, sign_mk_attrib): Add nrsign command, don't allow revoking a nonrevocable signature, * g10.c (main): Add --nrsign option to nonrevocably sign a key from the command line. * build-packet.c (build_sig_subpkt_from_sig): Comment to explain the use of CRITICAL. 2001-12-21 Werner Koch * g10.c. options.h : New option --show-keyring * getkey.c (get_ctx_handle): New. * keylist.c (list_one): Implement option here. By David Champion. 2001-12-20 David Shaw * keyserver.c (keyserver_spawn): Use mkdtemp() to make temp directory. * mkdtemp.c: replacement function for those platforms that don't have mkdtemp (make a temp directory securely). 2001-12-19 David Shaw * misc.c (check_permissions): New function to stat() and ensure the permissions of GNUPGHOME and the files have safe permissions. * keydb.c (keydb_add_resource): Check keyring permissions. * tdbio.c (tdbio_set_dbname): Check permissions of trustdb.gpg * keyserver.c (keyserver_spawn): Disable keyserver schemes that involve running external programs if the options file has unsafe permissions or ownership. * g10.c, options.h: New option --no-permission-warning to disable the permission warning message(s). This also permits use of the keyserver if it had been disabled (see above). Also check the permissions/ownership of random_seed. * keyserver.c (keyserver_spawn): The new glibc prints a warning when using mktemp() (the code was already secure, but the warning was bound to cause confusion). Use a different implementation based on get_random_bits() instead. Also try a few times to get the temp dir before giving up. 2001-12-19 Werner Koch * g10.c, passphrase.c [CYGWIN32]: Allow this as an alias for MINGW32. 2001-12-18 David Shaw * g10.c (idea_cipher_warn): Add a flag to show the warning always or once per session and change all callers (show always except for the secret key protection and unknown cipher from an encrypted message errors). Also make the strings translatable. * pubkey-enc.c (get_it): Add the IDEA cipher warning if the user tries to decrypt an IDEA encrypted message without the IDEA plugin. * keyserver.c (parse_keyserver_uri): More strict checking of the keyserver URI. Specifically, fail if the ":port" section is anything except a number between 1 and 65535. 2001-12-17 David Shaw * keyserver.c (print_keyinfo): No need to check for control/illegal characters, as utf8_to_native does this for us. * mainproc.c (proc_encrypted): Use generic IDEA warning. * gpgv.c: add stub for idea_cipher_warn * g10.c, hkp.c, keyserver.c: Fix capitalization and plural issues. * encode.c (encode_crypt), sign.c (sign_file, clearsign_file): disable pgp2 mode after the message is no longer pgp2 compatible. * g10.c (main): Tweak the PGP2.x IDEA warning to use the generic warning, and not merely fail if the IDEA plugin isn't there. * g10.c (main, idea_cipher_warn), keygen.c (set_one_pref), seckey-cert.c (do_check): Add a generic IDEA warning for when the IDEA plugin is not present.
