John the Ripper -- Changes History==================================== Changes from v1.4 to v1.5---------------------------* Everything is re-coded, to be far more extendable, more portable (noGNU C extensions used, unless __GNUC__ is defined), and more readable.* Bitslice DES routines: up to 3 times faster on RISC.* BSDI's extended DES-based ciphertext format support.* OpenBSD's Blowfish-based ciphertext format support.* Special assembly DES routines for x86 with MMX: +30% on a Pentium II.* Improved MD5 routines (both C and x86 assembly), 10...50% faster.* Smarter length switching in incremental mode.* Wordlist rules are now expanded while cracking, not at startup.* New options: '-session', '-groups'.* Simplified the syntax of '-users', '-shells', '-salts'.* Replaced '-noname' and '-nohash' with '-savemem'.* Replaced '-des' and '-md5' with '-format'.* Removed some obsolete options, to keep the thing simple.* Added 'continue', 'break', 'return' to the built-in compiler.* You can now use C comments in external mode definitions.* Better default rule sets: variable length limit, less redundancy.* Many internal algorithm improvements. Changes from v1.3 to v1.4---------------------------* MD5-based password files support.* SPARC V8 assembly DES routines.* A lot of bugfixes.Versions earlier than v1.3 are probably not worth mentioning here now...
