org.bouncycastle.crypto.prng.ThreadedSeedGenerator
public class ThreadedSeedGenerator
extends java.lang.Object
A thread based seed generator - one source of randomness.
Based on an idea from Marcus Lippert.
byte[] | generateSeed(int numBytes, boolean fast) - Generate seed bytes.

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.
numBytes
- the number of bytes to generatefast
- true if fast mode should be used
