md5module.java

无线通信的主要编程软件,是无线通信工作人员的必备工具,关天相关教程我会在后续传上.

// 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.
