All Implemented Interfaces:

java.io.Serializable

public final class HMacSHA224SP80090Random
extends SecRandom

This class implements the NIST SP800-90 deterministic random bit generator using HMAC/SHA-224 as HMAC algorithm. It has a security strength of 112 bits. Note that this class has no speed advantages over HMacSHA256SP80090Random as SHA-224 is based on SHA-256.
