Class 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
