"I've been using CrypTool for years in internships for IT-Security at the University of Klagenfurt and Distance Learning Computer Science at the University of Applied Science Trier. CrypTool is used here among the students with enthusiasm because in many cases it awakes the play instincts in the up-and-coming computer scientists (e.g. through manual decryption of ciphertexts or number games.) If only learning were always such fun, then it would be much easier for us students!"
