Apple IIgs Crypto tool set v1.0

The Vision:
A tool set that provides a library of encryption and decryption functions using a variety of algorithms.

Version 1.0
desCipher - DES encryption and decryption
The DES cipher routines were implemented by Robert V. Medshaw.
desAddParity - adds parity bits to a 56-bit key

The source code for the tool set has been released under the GNU Lesser General Public License so that others can contribute to the development of the tool set.
The source code for the tool set has been made available in CVS as part of the Marinetti Open Source Project.
The DES cipher routines have not been placed in CVS for two reasons:
1) as they are Copyright 1979 BYTE Magazine
2) US Government Export restrictions
