java.lang.Objectjava.security.MessageDigestSpi
org.apache.mina.proxy.utils.MD4
public class MD4
MD4.java - An implementation of Ron Rivest's MD4 message digest algorithm. The MD4 algorithm is designed to be quite fast on 32-bit machines. In addition, the MD4 algorithm does not require any large substitution tables.
MD4 Message-
