      • initialize

        public void initialize​(java.security.spec.AlgorithmParameterSpec params,
                               java.security.SecureRandom random)
                        throws java.security.InvalidAlgorithmParameterException,
                               java.security.InvalidParameterException
        Initializes this KeyPairGenerator for given parameters and secure random source.
        Overrides:
        initialize in class java.security.KeyPairGenerator
        Parameters:
        params - the RSAKeyParameterSpec for this object.
        random - the SecureRandom object for generating random numbers.
        Throws:
        java.security.InvalidAlgorithmParameterException - thrown when parameter set is not recognized.
        java.security.InvalidParameterException
      • initialize

        public void initialize​(int strength,
                               java.security.SecureRandom random)
                        throws java.security.InvalidParameterException
        Initializes this KeyPairGenerator for given modulus size and secure random source. The private key will be stored in the CLEAR not the hardware or the PKDS, the private key label will be randomly generated and the key will be used for signing purposes.
        Overrides:
        initialize in class java.security.KeyPairGenerator
        Parameters:
        strength - the length of the key to be generated.
        random - the SecureRandom object for generating a random number.
        Throws:
        java.security.InvalidParameterException - thrown when a parameter is not recognized.
      • generateKeyPair

        public java.security.KeyPair generateKeyPair()
        Generates an RSA key pair.
        Overrides:
        generateKeyPair in class java.security.KeyPairGenerator
        Returns:
        a KeyPair contains a pair of generated RSA keys
        Throws:
        java.lang.IllegalArgumentException - in the key label formal is not valid
      • getGenerator

        protected void getGenerator()
        Creates an instance of the KeyPairGenerator.
        Throws:
        java.lang.RuntimeException - if this method fails to create and to initialize the message digest.
