        public GMSSKeyPairGenerator​(GMSSDigestProvider digestProvider)

        Parameters:
        digestProvider - provider for digest implementations.

      • initialize

        public void initialize​(int keySize,
                       java.security.SecureRandom secureRandom)
        This method initializes the GMSS KeyPairGenerator using an integer value keySize as input. It provides a simple use of the GMSS for testing demands.

        A given keysize of less than 10 creates an amount 2^10 signatures. A keySize between 10 and 20 creates 2^20 signatures. Given an integer greater than 20 the key pair generator creates 2^40 signatures.

        Parameters:
        keySize - Assigns the parameters used for the GMSS signatures. There are 3 choices:
        1. keysize <= 10: creates 2^10 signatures using the parameterset
        P = (2, (5, 5), (3, 3), (3, 3))
        2. keysize > 10 and <= 20: creates 2^20 signatures using the parameterset
        P = (2, (10, 10), (5, 4), (2, 2))
        3. keysize > 20: creates 2^40 signatures using the parameterset
        P = (2, (10, 10, 10, 10), (9, 9, 9, 3), (2, 2, 2, 2))
        secureRandom - not used by GMSS, the SHA1PRNG of the SUN Provider is always used

      • initialize

        public void initialize​(KeyGenerationParameters param)
        Initalizes the key pair generator using a parameter set as input
