Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
+ *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
+ used (char *) instead of (void *) and had casts all over the place.
+ [Steve Henson]
+
+ *) Make BN_generate_prime() return NULL on error if ret!=NULL.
+ [Ulf Möller]
+
+ *) Retain source code compatibility for BN_prime_checks macro.
+ [Ulf Möller]
+
+ *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
+ DH_CHECK_P_NOT_SAFE_PRIME.
+ (Check if this is true? OpenPGP calls them "strong".)
+ [Ulf Möller]
+
+ *) Merge the functionality of "dh" and "gendh" programs into a new program
+ "dhparam". The old programs are retained for now but will handle DH keys
+ (instead of parameters) in future.
+ [Steve Henson]
+
+ *) Make the ciphers, s_server and s_client programs check the return values
+ when a new cipher list is set.
+ [Steve Henson]
+
+ *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
+ ciphers. Before when the 56bit ciphers were enabled the sorting was
+ wrong.
+
+ The syntax for the cipher sorting has been extended to support sorting by
+ cipher-strength (using the strength_bits hard coded in the tables).
+ The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
+
+ Fix a bug in the cipher-command parser: when supplying a cipher command
+ string with an "undefined" symbol (neither command nor alphanumeric
+ [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
+ an error is flagged.
+
+ Due to the strength-sorting extension, the code of the
+ ssl_create_cipher_list() function was completely rearranged. I hope that
+ the readability was also increased :-)
+ [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
+
+ *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
+ for the first serial number and places 2 in the serial number file. This
+ avoids problems when the root CA is created with serial number zero and
+ the first user certificate has the same issuer name and serial number
+ as the root CA.
+ [Steve Henson]
+
*) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
the new code. Add documentation for this stuff.
[Steve Henson]
(1 = ok, 0 = not seeded). Also an error is recorded on the thread's
error queue. New function RAND_pseudo_bytes() generates output that is
guaranteed to be unique but not unpredictable.
- (TO DO: always check the result of RAND_bytes when it is used in the
- library, or use RAND_pseudo_bytes instead, because leaving the
- error in the error queue but reporting success in a function that
- uses RAND_bytes could confuse things considerably.)
[Ulf Möller]
*) Do more iterations of Rabin-Miller probable prime test (specifically,
3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
- instead of only 2 for all lengths; see BN_prime_checks definition
- in crypto/bn/bn.h for the complete table). This guarantees a
+ instead of only 2 for all lengths; see BN_prime_checks_size definition
+ in crypto/bn/bn_prime.c for the complete table). This guarantees a
false-positive rate of at most 2^-80 (actually less because we are
additionally doing trial division) for random input.
