    • Method Detail

      • getAlgorithmName

        java.lang.String getAlgorithmName()
        return the algorithm name
        Returns:
        the algorithm name
      • getDigestSize

        int getDigestSize()
        return the size, in bytes, of the digest produced by this message digest.
        Returns:
        the size, in bytes, of the digest produced by this message digest.
      • update

        void update​(byte in)
        update the message digest with a single byte.
        Parameters:
        in - the input byte to be entered.
      • update

        void update​(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.
      • doFinal

        int doFinal​(byte[] out,
                    int outOff)
        close the digest, producing the final digest value. The doFinal call leaves the digest reset.
        Parameters:
        out - the array the digest is to be copied into.
        outOff - the offset into the out array the digest is to start at.
      • reset

        void reset()
        reset the digest back to it's initial state.
