Class RandomDotOrgSeedGenerator

java.lang.Object

org.uncommons.maths.random.RandomDotOrgSeedGenerator

All Implemented Interfaces:

SeedGenerator

public class RandomDotOrgSeedGenerator
extends java.lang.Object
implements SeedGenerator

Connects to the random.org website (via HTTPS) and downloads a set of random bits to use as seed data. It is generally better to use the DevRandomSeedGenerator where possible, as it should be much quicker. This seed generator is most useful on Microsoft Windows and other platforms that do not provide /dev/random.
