This avoids any choosen input attacks which are not serious in our setting because an outsider won't be able to mix data in and even then we keep going with a PRNG. Thanks to Stefan Keller for pointing this out. 2002-01-04 Werner Koch * pubkey.c (gcry_pk_genkey): Do not release skey - it is static. * primegen.c (gen_prime): Of course we should use set_bit and not set_highbit to set the second high bit. 2001-12-18 Werner Koch * rsa.c (generate): Loop until we find the exact modulus size. Changed the exponent to 41. (rsa_get_info): s/usage/r_usage/ to avoid shadow warnings. * primegen.c (gen_prime): Set 2 high order bits for secret primes. * Makefile.am (DISTCLEANFILES): Include construct.c. 2001-12-17 Werner Koch * pubkey.c (gcry_pk_get_keygrip): New - experimental. 2001-12-11 Werner Koch * cipher.c: Added OIDs for AES.

(sexp_to_key): Add an arg to return the index of the algorithm, changed all callers. (gcry_pk_sign): Find the signature algorithm by name and not by number. (gcry_pk_get_nbits): Fixed so that we can now really pass a secret key to get the result. * md.c (gcry_md_map_name): Look also for OIDs prefixed with "oid." or "OID." so that an OID string can be used as an S-Exp token. 2001-11-20 Werner Koch * md.c (gcry_md_map_name): Lookup by OID if the the name begins with a digit. (oid_table): New. 2001-11-16 Werner Koch * md.c (gcry_md_info): New operator GCRYCTL_IS_ALGO_ENABLED. 2001-11-07 Werner Koch * md.c (gcry_md_hash_buffer): Close the handle which was left open for algorithms other than rmd160. 2001-08-08 Werner Koch * rndw32.c (gather_random): Use toolhelp in addition to the NT gatherer for Windows2000. Suggested by Sami Tolvanen. * random.c (read_pool): Fixed length check, this used to be one byte to strict. Made an assert out of it because the caller has already made sure that only poolsize bytes are requested. Reported by Marcus Brinkmann. 2001-08-03 Werner Koch * cipher.c (cipher_encrypt, cipher_decrypt): Prepare to return errors. We have to change the interface to all ciphers to make this really work but we should do so to prepare for hardware encryption modules. (gcry_cipher_encrypt, gcry_cipher_decrypt): Return the error and set lasterr. (gcry_cipher_ctl): Make sure that errors from setkey are returned. 2001-08-02 Werner Koch * rndlinux.c (gather_random): casted a size_t arg to int so that the format string is correct. Casting is okay here and avoids translation changes. * random.c (fast_random_poll): Do not check the return code of getrusage. * rndunix.c: Add a signal.h header to avoid warnings on Solaris 7 and 8. * tiger.c (print_abc,print_data): Removed. * rijndael.c, des.c, blowfish.c, twofish.c, cast5.c, arcfour.c (burn_stack): New. Add wrappers for most functions to be able to call burn_stack after the function invocation. This methods seems to be the most portable way to zeroise the stack used. It does only work on stack frame based machines but it is highly portable and has no side effects. Just setting the automatic variables at the end of a function to zero does not work well because the compiler will optimize them away - marking them as volatile would be bad for performance. * md5.c, sha1.c, rmd160.c, tiger.c (burn_stack): Likewise. * random.c (burn_stack): New. (mix_pool): Use it here to burn the stack of the mixblock function. * primegen.c (_gcry_generate_elg_prime): Freed q at 3 places. Thanks to Tommi Komulainen. * arcfour.c (arcfour_setkey): Check the minimim keylength against bytes and not bits.

Changed all g10_ prefixed function names as well as some mpi_ function names to cope with the introduced naming changes. * md.c (prepare_macpads): Made key const. 2001-05-28 Werner Koch * rndegd.c (gather_random): Removed the use of tty_printf. 2001-03-29 Werner Koch * md5.c (md5_final): Fixed calculation of hashed length. Thanks to disastry@saiknes.lv for pointing out that it was horrible wrong for more than 512MB of input. * sha1.c (sha1_final): Ditto. * rmd160.c (rmd160_final): Ditto. * tiger.c (tiger_final): Ditto. * blowfish.c (encrypt,do_encrypt): Changed name to do_encrypt to avoid name clashes with an encrypt function in stdlib.h of Dynix/PIX. Thanks to Gene Carter. * elgamal.c (encrypt,do_encrypt): Ditto. * twofish.c (gnupgext_enum_func): Use only when when compiled as a module. * rijndael.c (gnupgext_enum_func): Ditto. * tiger.c (tiger_get_info): Return "TIGER192" and not just "TIGER". By Edwin Woudt. * random.c: Always include time.h - standard requirement. Thanks to James Troup. * rndw32.c: Fixes to the macros. 2001-01-11 Werner Koch * cipher.c (cipher_encrypt,gcry_cipher_encrypt): Use blocksize and not 8. 2000-12-19 Werner Koch Major change: Removed all GnuPG stuff and renamed this piece of software to gcrypt. 2000-11-14 Werner Koch * dsa.c (test_keys): Replaced mpi_alloc by gcry_mpi_new and mpi_free by gcry_mpi_release. * elgamal.c (test_keys,generate): Ditto, also for mpi_alloc_secure. * rsa.c (test_keys,generate,rsa_verify): Ditto. * primegen.c (generate_elg_prime): Ditto.

(setup_cipher_table): Add Arcfour. (gcry_cipher_open): Kludge to allow stream mode. Wed Oct 4 13:16:18 CEST 2000 Werner Koch * sha1.c (transform): Use rol() macro. Actually this is not needed for a newer gcc but there are still aoter compilers. * rsa.c (test_keys): Use new random function. * md.c (gcry_md_setkey): New function to overcome problems with const conflics. (gcry_md_ctl): Pass set key to the new functions. * rijndael.c: New. * cipher.c: Add Rijndael support.

By Sam Roberts. * pubkey.c (gcry_pk_algo_info): Add GCRYCTL_GET_ALGO_USAGE. * rsa.c: Changed the comment about the patent. (secret): Speed up by using the CRT. For a 2k keys this is about 3 times faster. (stronger_key_check): New but unused code to check the secret key. * Makefile.am: Included rsa.[ch]. * pubkey.c: Enabled RSA support. (pubkey_get_npkey): Removed RSA workaround. Mon Jul 31 10:04:47 CEST 2000 Werner Koch * pubkey.c: Replaced all gcry_sexp_{car,cdr}_{data,mpi} by the new gcry_sexp_nth_{data,mpi} functions.

Suggested by Alec Habig. * elgamal.c (sign): Removed inactive code. * rsa.c, rsa.h: New based on the old module version (only in CVS for now). * pubkey.c (setup_pubkey_table): Added commented support for RSA. * rndunix.c (waitpid): New.

(update_random_seed_file): New. (read_pool): Do an initial extra seeding when level 2 quality random is requested the first time. This requestes at least POOLSIZE/2 bytes of entropy. Compined with the seeding file this should make normal random bytes cheaper and increase the quality of the random bytes used for key generation. * random.c (read_pool): Print a more friendly error message in cases when too much random is requested in one call. * random.c (fast_random_poll): Check whether RUSAGE_SELF is defined; this is not the case for some ESIX and Unixware, although they have getrusage(). * primegen.c (generate_elg_prime): All primes are now generated with the lowest random quality level. Because they are public anyway we don't need stronger random and by this we do not drain the systems entropy so much. * primegen.c (register_primegen_progress): New. * dsa.c (register_pk_dsa_progress): New. * elgamal.c (register_pk_elg_progress): New. * elgamal.c (wiener_map): New.
