        Description copied from interface: Digest
        return the algorithm name
        Specified by:
        getAlgorithmName in interface Digest
        Returns:
        the algorithm name

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

      • update

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

      • doFinal

        public int doFinal​(byte[] out,
                   int outOff)
        Description copied from interface: Digest
        close the digest, producing the final digest value. The doFinal call leaves the digest reset.

        Description copied from interface: Digest
        reset the digest back to it's initial state.
        Specified by:
        reset in interface Digest

      • getByteLength

        public int getByteLength()
        Description copied from interface: ExtendedDigest
        Return the size in bytes of the internal buffer the digest applies it's compression function to.
        Specified by:
        getByteLength in interface ExtendedDigest
        Returns:
        byte length of the digests internal buffer.
