        return the size, in bytes, of the digest produced by this message digest.
        Specified by:
        getDigestSize in interface Digest
        Returns:
        the size, in bytes, of the digest produced by this message digest.

      • update

        public void update​(byte pIn)
        Description copied from interface: Digest
        update the message digest with a single byte.
        Specified by:
        update in interface Digest
        Parameters:
        pIn - the input byte to be entered.

      • update

        public void update​(byte[] pIn,
                   int pInOff,
                   int pLen)
        Description copied from interface: Digest
        update the message digest with a block of bytes.
        Specified by:
        update in interface Digest
        Parameters:
        pIn - the byte array containing the data.
        pInOff - the offset into the byte array where the data starts.
        pLen - the length of the data.

      • doFinal

        public int doFinal​(byte[] pOut,
                   int pOutOffset)
        Description copied from interface: Digest
        close the digest, producing the final digest value. The doFinal call leaves the digest reset.
        Specified by:
        doFinal in interface Digest
        Parameters:
        pOut - the array the digest is to be copied into.
        pOutOffset - the offset into the out array the digest is to start at.

      • doFinal

        public int doFinal​(byte[] pOut,
                   int pOutOffset,
                   int pOutLen)
        Description copied from interface: Xof
        Output the results of the final calculation for this digest to outLen number of bytes.
        Specified by:
        doFinal in interface Xof
        Parameters:
        pOut - output array to write the output bytes to.
        pOutOffset - offset to start writing the bytes at.
        pOutLen - the number of output bytes requested.
        Returns:

      • doOutput

        public int doOutput​(byte[] pOut,

        Description copied from interface: Xof
        Start outputting the results of the final calculation for this digest. Unlike doFinal, this method will continue producing output until the Xof is explicitly reset, or signals otherwise.
        Specified by:
        doOutput in interface Xof
        Parameters:
        pOut - output array to write the output bytes to.
