John the Ripper credits. John the Ripper has been developed and is maintained by Solar Designer. I would like to thank the following people for their direct or indirect help in making John what it is now: * Matthew Kwan - for producing and letting everyone use his optimized DES S-box expressions (previously found in nonstd.c and sboxes.c, now replaced with Roman Rusakov's): http://www.darkside.com.au/bitslice/ * Bruce Ford and Rémi Guyomarch - for producing and permitting the use of their MMX implementation of Matthew Kwan's S-box expressions (previously found in x86-mmx.S and x86-sse.S, with modifications, now replaced with code based on Roman Rusakov's S-box expressions). * Dumplinger Boy (Dango-Chu) - for producing and letting everyone use his optimized DES S-box expressions making use of a vector conditional select operation such as on PowerPC with AltiVec (previously found in sboxes-s.c, now replaced with Roman Rusakov's): http://dango.chu.jp/hiki/?Enhanced+Bitslice+DES * Roman Rusakov - for the DES S-box expressions that current versions of John the Ripper use, as well as for optimization hints during early development of John the Ripper. * Eli Biham - for the great "bitslice" paper: http://www.cs.technion.ac.il/~biham/Reports/cs0891.ps.gz * Lionel Cons - for making me add Kerberos AFS passwords support, for reporting some bugs, and for many good suggestions. * stran9er - for tracking down the section alignment problem with MMX in the DOS and Win32 ports. * Authors of the contributed patches ever listed on John the Ripper homepage and/or placed into contrib/ directory on the FTP server - for those patches which, while not included into the official John the Ripper for various reasons, are nevertheless very helpful to many users. * All the people who have developed freeware crypt(3) implementations - for various tricks that I combined in my routines. * Niels Provos and Poul-Henning Kamp - for original Blowfish-based and MD5-based crypt(3), respectively, that my implementations are compatible with. * Alec Muffett - for the original wordlist rules syntax. * The SOrCErEr - for proving the large charset tables are worth implementing, and for introducing "-groups" in his cracker. * Jackal - for the format of john.pot and parts of the user interface. * Anton Ertl - for "Labels as Values" optimization that I use in compiler.c: http://www.complang.tuwien.ac.at/papers/ertl96diss.ps.gz * The developers of Cygwin - for Cygwin (at the time called Cygnus Developer's Kit) that I used for the Win32 port: http://www.cygwin.com * DJ Delorie - for DJGPP that I used for the DOS port: http://www.delorie.com/djgpp/ * Charles W Sandmann - for CWSDPMI, the DPMI server used with DJGPP. $Owl: Owl/packages/john/john/doc/CREDITS,v 1.15 2011/06/22 13:03:43 solar Exp $
