All Implemented Interfaces:

Cloneable
```
public class HMACT64
extends MessageDigest
implements 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).
