"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!"

New Version of CrypTool — CT 1.4.41 released
A new release of CrypTool 1 was published on March 27, 2018.
This mature version is available in 6 languages (German, English, Spanish, Polish, Serbian, and French). Compared to 1.4.40, it contains many small bug fixes and corrections (especially for functions using Animal, Flash, HTML, and PDF).
The website CryptoPrograms http://www.cryptoprograms.com is dedicated to create and solve classical ciphers online. New on this site are analyzers for solving classical ciphers without any knowledge of the keyword and, in many cases, the key length. Routines for solving around 40 cipher types are provided.
Free Cryptography Course from Stanford Professor Dan Boneh
This course explains the inner workings of cryptographic functions and how to correctly use them. The course starts till end of March 2012 and will last at least 5 weeks. Normally, students have to work through the exercises in the same week the lessons are published.
