Class RC564Engine

public class RC564Engine extends Object implements BlockCipher

The specification for RC5 came from the RC5 Encryption Algorithm publication in RSA CryptoBytes, Spring of 1995. http://www.rsasecurity.com/rsalabs/cryptobytes.

This implementation is set to work with a 64 bit word size.

Implementation courtesy of Tito Pena.
