        public SecureRandomGSK()
        Constructs a new instance of this class.

      • SecureRandomGSK

        public SecureRandomGSK​(byte[] seed)
        Constructor that requires a seed. This seed has no real meaning to underlying System SSL random number generation services. This constructor only exists for compatability with SecureRandomSpi.
        Parameters:
        seed - a series of bytes. This parameter is ignored.

      • engineSetSeed

        public void engineSetSeed​(byte[] seed)
        This method has no meaning to underlying System SSL random number generation services, but is defined in SecureRandomSpi. This method is treated as a no-op whenever called.
        Specified by:
        engineSetSeed in class java.security.SecureRandomSpi
        Parameters:
        seed - a series of bytes. This parameter is ignored.

      • engineNextBytes

        public void engineNextBytes​(byte[] bytes)
                     throws java.lang.InternalError,
                            java.lang.RuntimeException
        Generates a user-specified number of random bytes.
        Specified by:
        engineNextBytes in class java.security.SecureRandomSpi
        Parameters:
        bytes - the array to be filled in with random bytes.
        Throws:
        java.lang.InternalError - is thrown when an unexpected error occurs.
        java.lang.RuntimeException - is thrown when a System SSL error occurs.

      • engineGenerateSeed

        public byte[] engineGenerateSeed​(int numBytes)
                          throws java.lang.UnsupportedOperationException
        This method has no meaning to underlying System SSL random number generation services, but is defined in SecureRandomSpi.
        Specified by:
        engineGenerateSeed in class java.security.SecureRandomSpi
        Throws:
        java.lang.UnsupportedOperationException - is always thrown if this method is invoked.
