All Implemented Interfaces:

java.lang.Cloneable

public class HMACT64

extends java.security.MessageDigest

implements java.lang.Cloneable

This is an implementation of the HMACT64 keyed hashing algorithm. HMACT64 is defined by Luke Leighton as a modified HMAC-MD5 (RFC 2104) in which the key is truncated at 64 bytes (rather than being hashed via MD5).
