I would like to thank several people who helped in mcrypt, especially the
designers of these unpatented algorithms which mcrypt uses and its security
relies on. 

The Designers of the algorithms:

DES: IBM & NSA 
(IBM's Lucifer: Roy Adler, Don Coppersmith, Horst Feistel, Edna Grossman,
Alan Konheim, Carl Meyer, Bill Notz, Lynn Smith, Walt Tuchman and
Bryant Tuckerman)
CAST: Carlisle Adams & Stafford Tavares
xTEA: David Wheeler & Roger M. Needham 
3-WAY: Joan Daemen
Blowfish/Twofish: Counterpane Systems (Bruce Schneier)
GOST: A.Zabotin (project leader), G.P. Glazkov, and V.B. Isaeva
SAFER: J.L. Massey
RC2/RC6: Ron Rivest
IDEA: J.L. Massey, Xuejia Lai

I've adopted code from the following sources:

The linux shadow password suite (getpass.c)
gzip (many ideas, and interface)
The GNUPrivacyGuard project (many ideas)
comp.compression faq (crc32)
bzip2 (crc32)
Crypt Breakers Workbench (enigma/unix crypt)
Steve Reid <sreid@sea-to-sky.net> (CAST-128)
Bruce Schneier's "Applied Cryptography" (BLOWFISH)
Phil Karn, Jim Gillogly (DES)
Richard De Moliner (demoliner@isi.ee.ethz.ch) (SAFER, IDEA)
David Wheeler & Roger M. Needham (TEA/extended)
Unknown (GOST/3-WAY)
gettext (all the internationalization code)
Tom St Denis (RC6)
