      • update

         void update(byte in)

        update the message digest with a single byte.

        Parameters:
        in - the input byte to be entered.

      • update

         void update(Array<byte> in, int inOff, int len)

        update the message digest with a block of bytes.

        Parameters:
        in - the byte array containing the data.
        inOff - the offset into the byte array where the data starts.
        len - the length of the data.

      • reset

         void reset()

        reset the digest back to it's initial state.

      • getByteLength

         int getByteLength()

        Return the size in bytes of the internal buffer the digest applies it's compression function to.

        Returns:

        byte length of the digests internal buffer.
