      • nativeGetAlgorithmDescription

        public static int nativeGetAlgorithmDescription​(byte[] algorithmBytes,
                                                byte[] description)
        Gets for the given algorithm the message digest description.

        description must be filled-in with:

        • [0-3]: digestLength: length of the message digest in bytes
        Parameters:
        algorithmBytes - Null terminated string that describes the algorithm
        description - the output buffer to fill in (see above).
        Returns:
        algorithm ID on success or -1 on error.
