* random.c (fast_random_poll): Only use times() if we HAVE_TIMES.

to load CryptRandom module.
2002-10-12 Werner Koch <wk@gnupg.org>
* rndunix.c (my_popen): Make sure that stdin and stderr are
connected to a file. This is to avoid NetBSD to complain about
set{u,g}id programs invoked with fd 0, 2 closed. Reported by
Cristian Biere.
(start_gatherer): Likewise. Reordered code.
2002-10-02 David Shaw <dshaw@jabberwocky.com>
* tiger.c (tiger_get_info): Select the OID to use for TIGER at
compile time.
2002-09-27 David Shaw <dshaw@jabberwocky.com>

enabled.
2002-09-26 Werner Koch <wk@gnupg.org>

breaks all TIGER generated signatures; if we want to do something
about it we have to do it in ../g10/sig-check.c .
2002-09-17 Werner Koch <wk@gnupg.org>
* rndw32.c (SIZEOF_DISK_PERFORMANCE_STRUCT): Increased to 256.

an algorithms was loaded.
(load_digest_module): Simplified by removing all the dynload code.

this module.
* idea-stub.c: New.
* blowfish.h (idea_get_info): Add prototype.
* cipher.c (setup_cipher_table): Try to load IDEA.
(load_cipher_modules): Removed all dynload code.

2002-07-25 David Shaw <dshaw@jabberwocky.com>
* random.c: "warning" -> "WARNING"
2002-07-02 Werner Koch <wk@gnupg.org>
* rndw32.c (slow_gatherer_windowsNT): Use a simple array for the
disk performance structure and increase it to the size required by
W2000.
2002-06-29 Werner Koch <wk@gnupg.org>
* rndlinux.c: Removed HAVE_LINUX_RANDOM_H conditional because it
was never used and the configure test did set the wrong macro
anyway.
2002-05-07 Stefan Bellon <sbellon@sbellon.de>
* md.c (md_start_debug): Use EXTSEP_S instead of ".".
2002-04-24 Werner Koch <wk@gnupg.org>

2002-04-18 Werner Koch <wk@gnupg.org>
* rndlinux.c, rndegd.c, rndunix.c (func_table): Made func a
function pointer. Note that we still need to change the module
interface to cope with data vs function pointer problems. Hmmm,
even dlsym has a problem with this.
2002-04-10 David Shaw <dshaw@jabberwocky.com>
* cipher.c (setup_cipher_table, cipher_open, cipher_encrypt,
cipher_decrypt, dummy_setkey, dummy_encrypt_block,
dummy_decrypt_block): the dummy cipher should only be built on
development versions.
2002-04-06 Werner Koch <wk@gnupg.org>
* rijndael.c (rijndael_get_info): We do only support a 128 bit
blocksize so it makes sense to change the algorithm strings to
AES.
* cipher.c (string_to_cipher_algo): Map "RIJNDAEL" to "AES".
2002-02-14 Werner Koch <wk@gnupg.org>
* random.c (mix_pool): Removed the failsafe stuff again. It makes
the code more complicate and may give the path to more bugs.
2002-02-10 Werner Koch <wk@gnupg.org>
* random.c (mix_pool): Carry an extra failsafe_digest buffer
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.
2002-01-02 Stefan Bellon <sbellon@sbellon.de>
* rndriscos.c [__riscos__]: Updated include file name.
2001-12-21 Werner Koch <wk@gnupg.org>

Changed the exponent to 41.
2001-10-22 Werner Koch <wk@gnupg.org>
* Makefile.am: Need to use $(EXEEXT) where approriate.
2001-09-09 Werner Koch <wk@gnupg.org>
* rsa.c (rsa_get_info): s/usage/r_usage/ to avoid shadow warnings.
2001-08-24 Werner Koch <wk@gnupg.org>
* md.c (md_write): Made buf arg const.
2001-08-22 Werner Koch <wk@gnupg.org>
* random.c (fast_random_poll): Don't use gethrtime if it is broken.
2001-08-20 Werner Koch <wk@gnupg.org>
Applied patches from Stefan Bellon <sbellon@sbellon.de> to support
RISC OS. Nearly all of these patches are identified by the
__riscos__ macro.
* blowfish.c, twofish.c: Added pragmas for use with a Norcraft
compiler.
* dynload.c, md5.c, rmd160.c, sha1.c: Minor patches for RISC OS.
* rndriscos.c: New.
* rnd-internal.h: Added prototype.
* random.c (fast_random_poll): Use '#if defined' instead of just
'defined'; needed for RISC OS.
* primegen.c (gen_prime): count? are now ints for consistence
with is_prime().
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.
2001-07-18 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.
2001-06-12 Werner Koch <wk@gnupg.org>
* cipher.c (string_to_cipher_algo): Use ascii_strcasecmp().
* md.c (string_to_digest_algo): Ditto.
* pubkey.c (string_to_pubkey_algo): Ditto.
* rndw32.c (slow_gatherer_windowsNT): Ditto. Not really needed
here but anyway.

* rndunix.c: Add a signal.h header to avoid warnings on Solaris 7
and 8.
2001-04-16 Werner Koch <wk@gnupg.org>
* dynload.c [__MINGW32__]: Applied patch from Timo Schulz to make
it work under W32. This patches is based on the one from
Disastry@saiknes.lv
2001-04-06 Werner Koch <wk@gnupg.org>
* rijndael.c, des.c, blowfish.c, twofish.c, cast5.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.
2001-04-02 Werner Koch <wk@gnupg.org>
* primegen.c (generate_elg_prime): I was not initialized for mode
!= 1. Freed q at 3 places. Thanks to Tommi Komulainen.
2001-03-28 Werner Koch <wk@gnupg.org>
* 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.
2001-03-19 Werner Koch <wk@gnupg.org>
* blowfish.c (encrypt,do_encrypt): Changed name to do_encrypt to
avoid name clahses with an encrypt function in stdlib.h of
Dynix/PIX. Thanks to Gene Carter.
* elgamal.c (encrypt,do_encrypt): Ditto.
2001-03-12 Werner Koch <wk@gnupg.org>
* twofish.c (gnupgext_enum_func): Add some static when comnpiled
as a module.

"TIGER". By Edwin Woudt.
2001-03-08 Werner Koch <wk@gnupg.org>
* random.c: Always include time.h - standard requirement. Thanks
to James Troup.
2001-01-18 Werner Koch <wk@gnupg.org>

2001-01-12 Werner Koch <wk@gnupg.org>

not 8 for CBC mode (However: we don't use CBS in OpenPGP).
2000-11-22 Werner Koch <wk@gnupg.org>
* rndegd.c (gather_random): Fixed default socket to be '=entropy'.
Thanks to Tomasz Kozlowski.
2000-10-12 Werner Koch <wk@gnupg.org>

* cipher.c: Add Rijndael support.
Wed Oct 4 15:50:18 CEST 2000 Werner Koch <wk@openit.de>

for a newer gcc but there are still aoter compilers.
Thu Sep 14 14:20:38 CEST 2000 Werner Koch <wk@openit.de>
* random.c (fast_random_poll): Check ENOSYS for getrusage.
* rndunix.c: Add 2 sources for QNX. By Sam Roberts.
Wed Sep 13 18:12:34 CEST 2000 Werner Koch <wk@openit.de>
* rsa.c (secret): Speed up by using the CRT. For a 2k keys this
is about 3 times faster.
