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 (found in nonstd.c and sboxes.c):

	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 (found in x86-mmx.S and x86-sse.S, with modifications).

* Eli Biham - for the great "bitslice" paper:

	http://www.cs.technion.ac.il/~biham/Reports/cs0891.ps.gz

* Roman Rusakov - for his optimization hints which affected early versions of John.

* 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:

* Charles W Sandmann - for CWSDPMI, the DPMI server used with DJGPP; the source code and/or binary updates for CWSDPMI may be obtained at:
