I just sent the first edition of Cipher Tools to RDS.

What's in it:
    A Feistel utility
    A keyed shuffler
    An S-box substituter
    An S-box inverter
    A permutator
    A keyed latin square generator/shuffler
    Bitwise shift-left functions for atoms and objects
    The SHA-1 hash algorithm
    Sloppy code
    No error checking
    Room for optimization

I've also attached crack.e, containing a tool to recover keys scrambled
        by
the Encrypt() function in Hawke''s Crypto10.e (not included).

        Questions, comments, concerns, and donations welcome. This is my first
public release, so tell me if I did anything stupid. (I just caught some
remnants of debug code an hour ago, so let me know if you find anything.)
