Method Detail

decryptBlock

byte[] decryptBlock(byte[] bytes,
                  int offSet,
                  int length)
                    throws InvalidCipherTextException

Decrypt a single block of data, returning the result.

Parameters:

bytes - array holding encrypted block.

offSet - offset into bytes where encrypted data starts.

length - the number of bytes of encrypted data in the bytes array.

Returns:

a byte array holding the decrypted data.

Throws:

InvalidCipherTextException - in the event the data is inappropriate for the cipher implemented.
