Class SecureRandomSeedGenerator

java.lang.Object
org.uncommons.maths.random.SecureRandomSeedGenerator
All Implemented Interfaces:
SeedGenerator

public class SecureRandomSeedGenerator extends Object implements SeedGenerator

SeedGenerator implementation that uses Java's bundled SecureRandom 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.
