OpenSSL CHANGES
_______________
Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ *) Implement binary inversion algorithm for BN_mod_inverse in addition
+ to the algorithm using long divison. The binary algorithm can be
+ used only if the modulus is odd. On 32-bit systems, it is faster
+ only for relatively small moduli (roughly 20-30% for 128-bit moduli,
+ roughly 5-15% for 256-bit moduli), so we use it only for moduli
+ up to 450 bits. In 64-bit environments, the binary algorithm
+ appears to be advantageous for much longer moduli; here we use it
+ for moduli up to 2048 bits.
+ [Bodo Moeller]
+
+ *) Change bctest again: '-x' expressions are not available in all
+ versions of 'test'.
+ [Bodo Moeller]
+
+ *) Fix a couple of memory leaks in PKCS7_dataDecode()
+ [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
+
+ *) Change Configure and Makefiles to provide EXE_EXT, which will contain
+ the default extension for executables, if any. Also, make the perl
+ scripts that use symlink() to test if it really exists and use "cp"
+ if it doesn't. All this made OpenSSL compilable and installable in
+ CygWin.
+ [Richard Levitte]
+
+ *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
+ could not support the combine flag in choice fields.
+ [Steve Henson]
+
+ *) Change bctest to avoid here-documents inside command substitution
+ (workaround for FreeBSD /bin/sh bug).
+ For compatibility with Ultrix, avoid shell functions (introduced
+ in the bctest version that searches along $PATH).
+ [Bodo Moeller]
+
+ *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
+ with des_encrypt() defined on some operating systems, like Solaris
+ and UnixWare.
+ [Richard Levitte]
+
+ *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
+ On the Importance of Eliminating Errors in Cryptographic
+ Computations, J. Cryptology 14 (2001) 2, 101-119,
+ http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
+ [Ulf Moeller]
+
+ *) MIPS assembler BIGNUM division bug fix.
+ [Andy Polyakov]
+
+ *) Disabled incorrect Alpha assembler code.
+ [Richard Levitte]
+
*) Fix bug in PKCS#12 key generation routines. This was triggered
if a 3DES key was generated with a 0 initial byte. Include
PKCS12_BROKEN_KEYGEN compilation option to retain the old
Fix leaks in PKCS12 and PKCS7 routines.
[Steve Henson]
- *) Fix for Irix with NO_ASM.
- ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
-
*) Add some EVP_add_digest_alias registrations (as found in
- OpenSSL_add_all_digests()), to SSL_library_init()
+ OpenSSL_add_all_digests()) to SSL_library_init()
aka OpenSSL_add_ssl_algorithms(). This provides improved
compatibility with peers using X.509 certificates
with unconventional AlgorithmIdentifier OIDs.
[Bodo Moeller]
+ *) Fix for Irix with NO_ASM.
+ ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
+
*) ./config script fixes.
[Ulf Moeller, Richard Levitte]
be handled deterministically).
[Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
+ *) Add a 'bctest' script that checks for some known 'bc' bugs
+ so that 'make test' does not abort just because 'bc' is broken.
+ [Bodo Moeller]
+
*) Store verify_result within SSL_SESSION also for client side to
avoid potential security hole. (Re-used sessions on the client side
always resulted in verify_result==X509_V_OK, not using the original
matter what.
[Richard Levitte]
+ *) Added several new manual pages for SSL_* function.
+ [Lutz Jaenicke]
+
Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
*) In ssl23_get_client_hello, generate an error message when faced
