+ * primegen.c (gen_prime): Assert that NBITS is never zero, it
+ would cause a segv.
+
2003-09-04 Werner Koch <wk@gnupg.org>
* pubkey.c (_gcry_pk_aliased_algo_name): New.
* ac.c (gcry_ac_open): Use it here.

2003-09-02 Moritz Schulte <mo@g10code.com>

functions.

the first one instead of the regular name to adhere to SPKI
conventions.

on error.

* random.c (gcry_random_bytes,gcry_random_bytes_secure)
(gcry_randomize): Make sure we are initialized.
2002-05-14 Werner Koch <wk@gnupg.org>
Changed license of most files to the LGPL.
2002-05-02 Werner Koch <wk@gnupg.org>

mutex can be used.
* primegen.c (small_prime_numbers): Moved table from smallprime.c
* smallprime.c: Fiel removed.
* des.c (leftkey_swap, rightkey_swap, working_memcmp): Made static.
* cipher.c (gcry_cipher_map_name): Map "RIJNDAEL" to "AES".

around to make the function more robust.
2002-02-08 Werner Koch <wk@gnupg.org>
* random.c (add_randomness): Xor new data into the pool and not
just copy it. 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 <wk@gnupg.org>
* pubkey.c (gcry_pk_genkey): Do not release skey - it is static.

and not set_highbit to set the second high bit.
2001-12-18 Werner Koch <wk@gnupg.org>
* rsa.c (generate): Loop until we find the exact modulus size.
Changed the exponent to 41.

(gcry_pk_get_nbits): Release the arrays. Noted by Nikos
Mavroyanopoulos.
2001-12-06 Werner Koch <wk@gnupg.org>
* cipher.c (gcry_cipher_map_name): Look also for OIDs prefixed
with "oid." or "OID.".
2001-12-05 Werner Koch <wk@gnupg.org>

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 <wk@gnupg.org>
* 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 <wk@gnupg.org>
* md.c (gcry_md_info): New operator GCRYCTL_IS_ALGO_ENABLED.
2001-11-07 Werner Koch <wk@gnupg.org>
* md.c (gcry_md_hash_buffer): Close the handle which was left open
for algorithms other than rmd160.
2001-08-08 Werner Koch <wk@gnupg.org>
* 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 <wk@gnupg.org>
* 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 <wk@gnupg.org>
* 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.

getrusage.
* rndunix.c: Add a signal.h header to avoid warnings on Solaris 7
and 8.

(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.

bytes and not bits.

avoid name clashes with an encrypt function in stdlib.h of
Dynix/PIX. Thanks to Gene Carter.

* 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.

to James Troup.
* rndw32.c: Fixes to the macros.
2001-01-11 Werner Koch <wk@gnupg.org>

(pubkey_get_npkey): Removed RSA workaround.

* pubkey.c: Replaced all gcry_sexp_{car,cdr}_{data,mpi} by the new
gcry_sexp_nth_{data,mpi} functions.
Tue Jul 25 17:44:15 CEST 2000 Werner Koch <wk@openit.de>
* pubkey.c (exp_to_key,sexp_to_sig,sexp_to_enc,gcry_pk_encrypt,

is not filled.

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.

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.
