  • engineSetSeed

    protected abstract void engineSetSeed(byte[] seed)

    Reseeds this SecureRandomSpi instance with the specified seed. The seed of this SecureRandomSpi instance is supplemented, not replaced.

    Parameters:

    seed - the new seed.

  • engineNextBytes

    protected abstract void engineNextBytes(byte[] bytes)

    Generates and stores random bytes in the given byte[] for each array element.

    Parameters:

    bytes - the byte[] to be filled with random bytes.

  • engineGenerateSeed

    protected abstract byte[] engineGenerateSeed(int numBytes)

    Generates and returns the specified number of seed bytes, computed using the seed generation algorithm used by this SecureRandomSpi.

    Parameters:

    numBytes - the number of seed bytes.

    Returns:

    the seed bytes
