java.lang.Objectorg.bouncycastle.crypto.prng.DigestRandomGenerator
public class DigestRandomGenerator
Random generation based on the digest with counter. Calling addSeedMaterial will always increase the entropy of the hash.
Internal access to the digest is synchronized so a single one of these can be shared.
