public class ThreadedSeedGenerator extends Object
Based on an idea from Marcus Lippert.
Method Summary | |
---|---|
byte[] | generateSeed(int numBytes, boolean fast)
Generate seed bytes. |
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
