- Jamie Kendall (University of Portsmouth): "Cryptographic Techniques for Network Security using CrypTool", April 2008, 91 pages
This project educates students in the basics of the field of classic and modern cryptography and the according cryptanalysis. The project explores the software CrypTool 1 extensively and comprises of a set of three one hour lab sheets as well as an accompanying report with the solutions.
- CrypTool 2 at CeBIT 2010
The University of Duisburg-Essen presented CrypTool 2 as e-learning platform, peers@play and the combination of both for distributed modern cryptanalysis.
- 15th Colloquium for infomation Systems Security Education Fairborn, Rong Yang, Layne Wallace and Ian Burchett: Teaching Cryptology At All Levels Using CrypTool, June 2011
[Abstract - This paper introduces cryptology in the framework of general cybersecurity and advocates that it is an appropriate mechanism for introducing security issues into the classroom at all level of the curriculum. A practical free software package called CrypTool which can be a major asset in any attempt to teach cryptology to a range of student audiences is presented. Applications and classroom experiences using CrypTool are discussed along with some student feedback.]
