People:

I am writing a cryptography book:  CRYPTOGRAPHY IN C: APPLICATIONS,
ALGORITHMS, AND SOURCE CODE.  The book will be published by John
Wiley & Sons next Autumn.  I have shelves of mathematical texts,
conference proceedings, graduate theses and monographs.  This book
will be different from all of them.  It will be a book written for
programmers, not mathematicians:  a lot of applications and
examples, and minimal number theory.

I am looking for two things from the people of this newsgroup: 
source code examples, and people willing to read and edit the
manuscript.

Source Code Examples.  I am looking for C source code (preferably
well-documented, but I'll take what I can get) for the following
algorithms:

Vigenare.
Playfair.
Enigma.  Has anyone recreated this in software?
DES.  I already have one DES, but I am looking for better/faster
     implementations.  I am also interested in DES variants:  GDES,
     DES with variable S-Boxes, etc.
Lucifer.  I remember this being on-line somewhere.
FEAL.  I have a paper copy of the reference implementation from
     NTT.  Has anyone typed it in and verified that it works.
LOKI.  Both the original and LOKI-91.
REDOC II.
Khufu and Khafre.  The Xerox patent has the listing of a C
     implementation of these algorithms.  Does anyone have them on-
     line?
Public-key anything.  I hope to get RSA's permission to publish
     RSAREF, but would like code for such things as a knapsack
     cryptosystem, Fiat-Shamir, El Gamal, Schnoor, elliptic-curve
     something, E-Sign, etc.
NIST's Digital Signature Standard.
Prime number generators:  Rabin-Miller, Solovay-Strassen, Lehmann,
     etc.
Factorization programs:  Pollard's Monte Carlo algorithm, the
     continued fraction algorithm, Pomerance's quadratic sieve,
     etc.
The Blum-Blum-Shub Pseudo-Random Number Generator, and the
     probabilistic encryption algorithm based on it.
Any zero-knowledge implementations of anything.
Any threshold scheme.
Anything else not on this list that would be a good idea to
     include.

I already have code for DES, SHA, IDEA, MD4, MD5, and Snefru.  I
will include much from PGP (possibly the whole thing if the various
lawyers think it is a good idea).

Editors:  I am also looking for people who are willing to read and
edit the manuscript in January.  I am interested in people who have
knowledge of cryptography, but also in people who are programmers
with an interest (my target audience).

I would appreciate the help of anyone who is interested.  This is
an exciting project, and I hope the results will be a source book
in the field.

Attached is the current incarnation of the table of contents. 
Actual table of contents will probably be different.
