org.bouncycastle.crypto.prng.ThreadedSeedGenerator.generateSeed()
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.
@param numBytes the number of bytes to generate @param fast true if fast mode should be used

        SecureRandom random = new SecureRandom();


        /*
         * Hopefully, 20 bytes in fast mode are good enough.
         */
        random.setSeed(tsg.generateSeed(20, true));


        return random;
    }
