      • engineInit

        protected void engineInit​(java.security.SecureRandom random)
        Initializes this key generator.
        Specified by:
        engineInit in class javax.crypto.KeyGeneratorSpi
        Parameters:
        random - the source of randomness for this generator

      • engineInit

        protected void engineInit​(java.security.spec.AlgorithmParameterSpec params,
                          java.security.SecureRandom random)
                   throws java.security.InvalidAlgorithmParameterException

        Specified by:
        engineInit in class javax.crypto.KeyGeneratorSpi
        Parameters:
        params - the key generation parameters
        random - the source of randomness for this key generator
        Throws:
        java.security.InvalidAlgorithmParameterException - if params is inappropriate for this key generator

      • engineInit

        protected void engineInit​(int keysize,
                          java.security.SecureRandom random)
