	register function prototype.

2002-05-17  Werner Koch  <wk@gnupg.org>

	* rndegd.c (rndegd_constructor): Fixed name of register function

2002-02-08  Werner Koch  <wk@gnupg.org>

	just copy it.  This avoids any choosen input attacks which are not

	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.

	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.

2001-08-08  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

	encryption modules.
	(gcry_cipher_encrypt, gcry_cipher_decrypt): Return the error and
	set lasterr.

2001-08-02  Werner Koch  <wk@gnupg.org>

	getrusage.

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

	* 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.

	* 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.

	to gcrypt. 

2000-11-14  Werner Koch  <wk@gnupg.org>

	* 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.

  * rndunix.c (waitpid): New. For UTS 2.1.  All by Dave Dykstra.
  (my_popen): Do the FD_CLOEXEC only if it is available

  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.
