public class NullCipher
extends Cipher

The NullCipher class is a class that provides an "identity cipher" -- one that does not tranform the plaintext. As a consequence, the ciphertext is identical to the plaintext. All initialization methods do nothing, while the blocksize is set to 1 byte.

Since:
  JCE1.2
