27 o Read only memory BIOs and simplified creation function
28 o TLS/SSL code now "tolerates" MS SGC
29 o RSA_NULL option that removes RSA patent code but keeps other
31 o Memory leak detection now allows applications to add extra information
32 via a per-thread stack
33 o PRNG robustness improved
35 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
37 o Transparent support for PKCS#8 format private keys: these are used
38 by several software packages and are more secure than the standard
40 o PKCS#5 v2.0 implementation
41 o Password callbacks have a new void * argument for application data
42 o Avoid various memory leaks
43 o New pipe-like BIO that allows using the SSL library when actual I/O
44 must be handled by the application (BIO pair)
46 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
47 o Lots of enhancements and cleanups to the Configuration mechanism
48 o RSA OEAP related fixes
49 o Added `openssl ca -revoke' option for revoking a certificate
50 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
51 o Source tree cleanups: removed lots of obsolete files
52 o Thawte SXNet, certificate policies and CRL distribution points
54 o Preliminary (experimental) S/MIME support
55 o Support for ASN.1 UTF8String and VisibleString
56 o Full integration of PKCS#12 code
57 o Sparc assembler bignum implementation, optimized hash functions
58 o Option to disable selected ciphers
60 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
61 o Fixed a security hole related to session resumption
62 o Fixed RSA encryption routines for the p < q case
63 o "ALL" in cipher lists now means "everything except NULL ciphers"
64 o Support for Triple-DES CBCM cipher
65 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
