Constructor Details

SecureRandomGSK

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.

Method Details

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 SecureRandomSpi

Parameters:

seed - a series of bytes. This parameter is ignored.

engineNextBytes

public void engineNextBytes(byte[] bytes)
                     throws InternalError,
RuntimeException

Generates a user-specified number of random bytes.

Specified by:

engineNextBytes in class SecureRandomSpi

Parameters:

bytes - the array to be filled in with random bytes.

Throws:

InternalError - is thrown when an unexpected error occurs.

RuntimeException - is thrown when a System SSL error occurs.

engineGenerateSeed

public byte[] engineGenerateSeed(int numBytes)
                          throws UnsupportedOperationException

This method has no meaning to underlying System SSL random number generation services, but is defined in SecureRandomSpi.

Specified by:

engineGenerateSeed in class SecureRandomSpi

Throws:

UnsupportedOperationException - is always thrown if this method is invoked.
