        Returns:

      • addPadding

        public int addPadding​(byte[] in,
                              int inOff)
        add the pad bytes to the passed in block, returning the number of bytes added.

        Note: this assumes that the last block of plain text is always passed to it inside in. i.e. if inOff is zero, indicating the entire block is to be overwritten with padding the value of in should be the same as the last block of plain text.
