public class SerpentEngine
extends java.lang.Object
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.>

init
public void init(boolean encrypting,
CipherParameters params)
initialise a Serpent cipher.
- init in interface BlockCipher
encrypting
- whether or not we are for encryption.params
- the parameters required to set up the cipher.
processBlock
public final int processBlock(byte[] in,
int inOff,
byte[] out,
int outOff)
Process one block of input from the array in and write it to
the out array.
- processBlock in interface BlockCipher
in
- the array containing the input data.inOff
- offset into the in array the data starts at.out
- the array the output data will be copied into.outOff
- the offset into the out array the output will start at.
- the number of bytes processed and produced.
