PTEACypher Class Reference
#include <cypher.h>
List of all members.
Detailed Description
Tiny Encryption Algorithm. This class implements the Tiny Encryption Algorithm by David Wheeler and Roger Needham at Cambridge University.
This is a simple algorithm using a 128 bit binary key and encrypts data in 64 bit blocks.
