      • generateSeed

        public byte[] generateSeed​(int numBytes,
                                   boolean fast)
        Generate seed bytes. Set fast to false for best quality.

        If fast is set to true, the code should be round about 8 times faster when generating a long sequence of random bytes. 20 bytes of random values using the fast mode take less than half a second on a Nokia e70. If fast is set to false, it takes round about 2500 ms.

        Parameters:
        numBytes - the number of bytes to generate
        fast - true if fast mode should be used
