"CrypTool educates PC users about the basics of cryptography in a fascinating way. It allows the exploration of various crypto mechanisms in a very illustrative way. The implementation of ancient algorithms provides an interesting walk through the history of cryptology - ending up with a comprehensive demonstration of all modern implementations."
