History

The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001.[2]

Currently 4 versions of CrypTool are maintained and developed: The CrypTool 1 (CT1) software is available in 6 languages (English, German, Polish, Spanish, Serbian, and French). CrypTool 2 (CT2), JCrypTool (JCT), and CrypTool-Online (CTO) are available in English and German.[3] CrypTool 2 builds upon its predecessor, CrypTool 1 by introducing more cryptographic types and analysis tools. [4]

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.[5]

CrypTool 1 (CT1) 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 CrypTool program. Both successors regularly publish new stable versions:

  • CrypTool 2[6][7] (built with C#/.NET/WPF) (abbreviated CT2)
uses the concept of visual programming to clarify cryptographic processes. Currently, CT2 contains more than 150 crypto functions.

  • JCrypTool 1.0[8][9] (built with Java/Eclipse/RCP/SWT) (abbreviated JCT)
runs on Windows, macOS, and Linux, and offers both a document-centric and a function-centric perspective. Currently, JCT contains more than 100 crypto functions. One of its focal points are modern digital signatures (like Merkle trees and SPHINCS).

The CrypTool project is now being developed at the research institute CODE at the Bundeswehr University Munich.[10]

CrypTool is used in schools, universities,[11] companies and agencies for education and awareness training.[12][13][14][15]
