"In addition to the appealing appearance and the extensive scope of operation, the team of CrypTool developers must also be praised. Wishes regarding missing functionality or suggestions for improvement are always promptly acted on and, where possible, integrated into new versions. In addition, the path chosen for recent developments is in my opinion a great success: Especially the building-block design with the independent modules (e.g: encryption, hashes or signature) that can be combined in activities, will be an inspiration for students.”
