Jython is an implementation of the high-level, dynamic, object-oriented language Python written in 100% Pure Java, and seamlessly integrated with the Java platform. It thus allows you to run Python on any Java platform.

There is a newer version: 2.7.4

// This is a JPython module wrapper around Harry Mantakos' md.java class,
// which provides the basic MD5 algorithm.  See also MD5Object.java which
// is the implementation of the md5 object returned by new() and md.java
// which provides the md5 implementation.
