Class BlowFish

  • All Implemented Interfaces:
    BlockCipher
    public class BlowFish
extends java.lang.Object
implements BlockCipher
    A class that provides Blowfish key encryption operations, such as encoding data and generating keys. All the algorithms herein are from Applied Cryptography and implement a simplified cryptography interface.
