com.hierynomus.security.jce.messagedigest.MD4

public class MD4
extends java.security.MessageDigest

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.

Since:

MINA 2.0.0-M3
