Class MD5

com.yahoo.collections.MD5

public class MD5
extends Object

Convenience class for hashing a String with MD5, and either returning an int with the 4 LSBytes, or the whole 12-byte MD5 hash.

Note that instantiating this class can be expensive, so re-using instances is a good idea.

This class is not thread safe.
