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

This class is not public and can therefore cannot be used outside this package.
