| Serpent | | final public class Serpent extends BlockCipher (Code) | | A bit-slice implementation in Java of the Serpent cipher.
Serpent is a 128-bit 32-round block cipher with variable key lengths,
including 128-, 192- and 256-bit
keys conjectured to be at least as secure as three-key triple-DES.
Serpent was designed by Ross Anderson, Eli Biham and Lars Knudsen as a
candidate algorithm for the NIST AES Quest.
