Class RC532Engine

Implemented Interfaces:
BlockCipher
public class RC532Engine
extends java.lang.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 has a word size of 32 bits.

Implementation courtesy of Tito Pena.
