| 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 Parameters: fast - true if fast mode should be used |
