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.

Init ( SecureRandom random ) : void

Initialise the padder.
PadCount ( byte input ) : int

return the number of pad bytes present in the block.
