562 data
563 o TLS/SSL code now "tolerates" MS SGC
564 o Work around for Netscape client certificate hang bug
565 o RSA_NULL option that removes RSA patent code but keeps other
566 RSA functionality
567 o Memory leak detection now allows applications to add extra information
568 via a per-thread stack
569 o PRNG robustness improved
570 o EGD support
571 o BIGNUM library bug fixes
572 o Faster DSA parameter generation
573 o Enhanced support for Alpha Linux
574 o Experimental MacOS support
576 Major changes between OpenSSL 0.9.3 and OpenSSL 0.9.4:
578 o Transparent support for PKCS#8 format private keys: these are used
579 by several software packages and are more secure than the standard
580 form
581 o PKCS#5 v2.0 implementation
582 o Password callbacks have a new void * argument for application data
583 o Avoid various memory leaks
584 o New pipe-like BIO that allows using the SSL library when actual I/O
585 must be handled by the application (BIO pair)
587 Major changes between OpenSSL 0.9.2b and OpenSSL 0.9.3:
588 o Lots of enhancements and cleanups to the Configuration mechanism
589 o RSA OEAP related fixes
590 o Added `openssl ca -revoke' option for revoking a certificate
591 o Source cleanups: const correctness, type-safe stacks and ASN.1 SETs
592 o Source tree cleanups: removed lots of obsolete files
593 o Thawte SXNet, certificate policies and CRL distribution points
594 extension support
595 o Preliminary (experimental) S/MIME support
596 o Support for ASN.1 UTF8String and VisibleString
597 o Full integration of PKCS#12 code
598 o Sparc assembler bignum implementation, optimized hash functions
599 o Option to disable selected ciphers
601 Major changes between OpenSSL 0.9.1c and OpenSSL 0.9.2b:
602 o Fixed a security hole related to session resumption
603 o Fixed RSA encryption routines for the p < q case
604 o "ALL" in cipher lists now means "everything except NULL ciphers"
605 o Support for Triple-DES CBCM cipher
606 o Support of Optimal Asymmetric Encryption Padding (OAEP) for RSA
607 o First support for new TLSv1 ciphers
608 o Added a few new BIOs (syslog BIO, reliable BIO)
609 o Extended support for DSA certificate/keys.
610 o Extended support for Certificate Signing Requests (CSR)
611 o Initial support for X.509v3 extensions
612 o Extended support for compression inside the SSL record layer
613 o Overhauled Win32 builds
614 o Cleanups and fixes to the Big Number (BN) library
615 o Support for ASN.1 GeneralizedTime
616 o Splitted ASN.1 SETs from SEQUENCEs
617 o ASN1 and PEM support for Netscape Certificate Sequences
618 o Overhauled Perl interface
619 o Lots of source tree cleanups.
620 o Lots of memory leak fixes.
621 o Lots of bug fixes.
623 Major changes between SSLeay 0.9.0b and OpenSSL 0.9.1c:
624 o Integration of the popular NO_RSA/NO_DSA patches
625 o Initial support for compression inside the SSL record layer
626 o Added BIO proxy and filtering functionality
