"I have been using CrypTool as a software tool to demonstrate the working principles of cryptographic algorithms and protocols, and to complement m lectures on computer and network security accordingly. My experience is that students like to work with CrypTool and to discover the wide range of cryptographic algorithms and protocols it implements. The tool provides an excellent playground to do lab studies and exercises."
