- org.uncommons.maths.random.SecureRandomSeedGenerator
-
- All Implemented Interfaces:
SeedGenerator
public class SecureRandomSeedGenerator extends Object implements SeedGenerator
SeedGenerator
implementation that uses Java's bundledSecureRandom
RNG to generate random seed data.The advantage of using SecureRandom for seeding but not as the primary RNG is that we can use it to seed RNGs that are much faster than SecureRandom.
This is the only seeding strategy that is guaranteed to work on all platforms and therefore is provided as a fall-back option should none of the other provided
SeedGenerator
implementations be useable.
