-/**
- * An implementation of SecureRandom specifically for the light-weight API, JDK
- * 1.0, and the J2ME. Random generation is based on the traditional SHA1 with
- * counter. Calling setSeed will always increase the entropy of the hash.
- * <p>
- * <b>Do not use this class without calling setSeed at least once</b>! There
- * are some example seed generators in the org.spongycastle.prng package.
