Changes between 0.9.4 and 0.9.5 [xx XXX 2000]
- *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
+ *) Support the EBCDIC character set completed.
+ [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
+
+ *) Source code cleanups: use const where appropriate, eliminate casts,
+ use void * instead of char * in lhash.
+ [Ulf Möller]
+
+ *) Bugfix: ssl3_send_server_key_exchange was not restartable
+ (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
+ this the server could overwrite ephemeral keys that the client
+ has already seen).
+ [Bodo Moeller]
+
+ *) Turn DSA_is_prime into a macro that calls BN_is_prime,
+ using 50 iterations of the Rabin-Miller test.
+
+ DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
+ iterations of the Rabin-Miller test as required by the appendix
+ to FIPS PUB 186[-1]) instead of DSA_is_prime.
+ As BN_is_prime_fasttest includes trial division, DSA parameter
+ generation becomes much faster.
+
+ This implies a change for the callback functions in DSA_is_prime
+ and DSA_generate_parameters: The callback function is called once
+ for each positive witness in the Rabin-Miller test, not just
+ occasionally in the inner loop; and the parameters to the
+ callback function now provide an iteration count for the outer
+ loop rather than for the current invocation of the inner loop.
+ DSA_generate_parameters additionally can call the callback
+ function with an 'iteration count' of -1, meaning that a
+ candidate has passed the trial division test (when q is generated
+ from an application-provided seed, trial division is skipped).
+ [Bodo Moeller]
+
+ *) New function BN_is_prime_fasttest that optionally does trial
+ division before starting the Rabin-Miller test and has
+ an additional BN_CTX * argument (whereas BN_is_prime always
+ has to allocate at least one BN_CTX).
+ 'callback(1, -1, cb_arg)' is called when a number has passed the
+ trial division stage.
+ [Bodo Moeller]
+
+ *) Fix for bug in CRL encoding. The validity dates weren't being handled
+ as ASN1_TIME.
[Steve Henson]
- *) Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when
- generating DSA primes.
- [Ulf Möller]
+ *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
+ [Steve Henson]
*) New function BN_pseudo_rand().
[Ulf Möller]
*) Make BN_generate_prime() return NULL on error if ret!=NULL.
[Ulf Möller]
- *) Retain source code compatibility for BN_prime_checks macro.
+ *) Retain source code compatibility for BN_prime_checks macro:
+ BN_is_prime(..., BN_prime_checks, ...) now uses
+ BN_prime_checks_for_size to determine the appropriate number of
+ Rabin-Miller iterations.
[Ulf Möller]
*) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
*) 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_size definition
+ instead of only 2 for all lengths; see BN_prime_checks_for_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.
+ false-positive rate of at most 2^-80 for random input.
[Bodo Moeller]
*) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
code.
[Steve Henson]
- *) Correctly increment the reference count in the SSL_SESSION pointer
- returned from SSL_get_session().
+ *) SSL_get1_session() is like SSL_get_session(), but increments
+ the reference count in the SSL_SESSION returned.
[Geoff Thorpe <geoff@eu.c2.net>]
*) Fix for 'req': it was adding a null to request attributes.
