Class MD5

  • public class MD5
extends java.lang.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.
