CrypTool
CrypTool is an open-source project that is a free e-learning software for illustrating cryptographic and cryptanalytic concepts.
The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001.
Currently 4 versions of CrypTool are maintained and developed: CrypTool 1 (CT1), CrypTool 2 (CT2), JCrypTool (JCT), and CrypTool-Online (CTO). All are available in English and German.
The goal of the CrypTool project is to make users aware of how cryptography can help against network security threats and to explain the underlying concepts of cryptology.
The development of CT1 started in 1998. It is written in C++ and designed for the Microsoft Windows operating system.
In 2007, development began on two additional projects, both based on a pure-plugin architecture, to serve as successors to the original CT1 program:
The browser software CrypTool-Online (CTO) has been in development since 2010 and is now the one most widely used.
Since 2023, the project has been managed by the CODE research institute at the Bundeswehr University Munich.
