                      throws JOSEException
        Computes a Hash-based Message Authentication Code (HMAC) for the specified secret and message.
        Parameters:
        alg - The Java Cryptography Architecture (JCA) HMAC algorithm name. Must not be null.
        secret - The secret. Must not be null.
        message - The message. Must not be null.
        provider - The JCA provider, or null to use the default one.
        Returns:
        A MAC service instance.
        Throws:
        JOSEException - If the algorithm is not supported or the MAC secret key is invalid.
