Sorry, I misspoke. You don't need to keep a reference to DigestRandomGenerator. But you *do* need to call SecureRandom.SetSeed() which is a wrapper around DigestRandomGenerator.AddSeedMaterial() var rng1 = new SecureRandom(new DigestRandomGenerator(new Sha256Digest())); // Now add some kind of seed material before trying to get random data out! rng1.SetSeed(someRandomBytes);
