The CrypTool project was and is supported by various institutions. Here you can find a selection.
The University of Siegen contributed an extensive number of features to the CrypTool project, e.g. by supervising several CrypTool related final exams at different universities. Additionally, the CrypTool project was presented at a big public event at the University of Siegen as a result of its award as Selected Landmark in the Land of Ideas, the biggest German nationwide event series in 2008.
The Ruhr-Universität Bochum provides the CrypTool project with special knowledge about several cryptology-related topics. Moreover, they supervise students who integrate functionality in CrypTool 2 and they administer the MysteryTwister website.
The DECRYPT project builds the DECODE database with more than 3000 encrypted historical documents and keys and it develops computer-aided tools for automatic decoding of historical source material by using AI and cross-disciplinary research involving computational linguistics, cryptology, history, linguistics and philology. One of the tools used is CrypTool 2 which is integrated in a web-based workflow ranging from upload, transcription, linguistic and historical analysis, cryptanalysis, and feedback loops. The project is financed by the Swedish Research Council, grant 2018-06074 (2018-2024).
The research institute CODE at the University of the Federal Armed Forces in Munich networks experts for cyber security from research, the military, business, industry, public authorities, and associations. Since end of 2019 the complete CrypTool Portal is hosted there, supervised by Prof. Wacker.
The department "Applied Information Security (Angewandte Informationssicherheit)", headed by Prof. Dr. Wacker, hosted the whole CrypTool website for several years. He also was the lead of the CrypTool 2 project.
The University of Duisburg-Essen has been in the CrypTool project since 2007 and entered into several commitments. Moreover, the core architecture team of the initial CrypTool 2.0 was based there.
CrypTool has been initially developed for the purpose of security awareness trainings within Deutsche Bank. After the initial requirements were met, Deutsche Bank handed CrypTool over to the opensource community. From the very beginning, Prof. Bernhard Esslinger was the main coordinator of the CrypTool project.
The Technische Universität Darmstadt hosted the former CrypTool website and the former CrypTool 1 source code repository. Now, they are mainly involved in the new JCrypTool project and assist in number theoretical issues.
Prof. Johannes Buchmann's research group "Cryptography and Computeralgebra" at TU Darmstadt develops the FlexiProvider library, an open-source Java library with cryptographic primitives and protocols. Further developments of the provider are accomplished in the context of the CASED research center and were integrated into BoucyCastle. Both, FlexiProvider and BouncyCastle, are used in JCrypTool.
The Warsaw University of Technoloy translated the CrypTool 1 e-learning software to Polish.
The "Spanish National Research Council" in Madrid ported the CrypTool 1 e-learning software to Spanish.
The Department "Secure Information Systems" at the University of Applied Sciences Upper Austria, Campus Hagenberg has been contributing to the JCrypTool project since 2007 by implementing many procedures, protocols, and visualizations.
The research group for system security contributes to quality assurance, as part of the beta testing team. They also provide ideas and feedback with respect to the further development of CrypTool in the academic area.
The Department for Informatics and Computing at Singidunum University has contributed plugins for network based communication between remote CrypTool 2 environments. These plugins are the result of many years of successful usage of CrypTool for teaching cryptology.
