CrypTool is an open up-source project[ane] that is a free due east-learning software for illustrating cryptographic and cryptanalytic concepts. Co-ordinate to "Hakin9",[two] CrypTool is worldwide the most widespread e-learning software in the field of cryptology.[3] [4]

CrypTool implements more than than 400 algorithms.[5] Users can adapt these with own parameters. To innovate users to the field of cryptography, the organization created multiple graphical interface software containing an online documentation, analytic tools and algorithms. They contain most classical ciphers, too as modern symmetric and asymmetric cryptography including RSA, ECC, digital signatures, hybrid encryption, homomorphic encryption, and Diffie–Hellman key exchange. Methods from the expanse of quantum cryptography (like BB84 cardinal exchange protocol) and the area of post-breakthrough cryptography (like McEliece, WOTS, Merkle-Signature-Scheme, XMSS, XMSS_MT, and SPHINCS) are implemented. In addition to the algorithms, solvers (analyzers) are included, especially for classical ciphers. Other methods (for instance Huffman code, AES, Keccak, MSS) are visualized.

In add-on it contains: didactical games (similar Number Shark, Divider Game, or Zudo-Ku) and interactive tutorials well-nigh primes, simple number theory, and lattice-based cryptography.

Development, history and roadmap [edit]

The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001. More than sixty people worldwide contribute regularly to the project. Contributions as software plugins came from universities or schools in the following towns: Belgrad, Berlin, Bochum, Brisbane, Darmstadt, Dubai, Duisburg-Essen, Eindhoven, Hagenberg, Jena, Kassel, Klagenfurth, Koblenz, London, Madrid, Mannheim, San Jose, Siegen, Utrecht, Warsaw.[6]

Currently iv versions of CrypTool are maintained and developed: The CrypTool i (CT1) software is available in 6 languages (English, German, Polish, Castilian, Serbian, and French). CrypTool 2 (CT2) is available in 3 languages (English, German, Russian). All others, JCrypTool (JCT) and CrypTool-Online (CTO), are available just in English language and German language.[7]

The goal of the CrypTool project is to make users aware of how cryptography tin help against network security threats and to explain the underlying concepts of cryptology.[eight]

CrypTool 1 (CT1) is written in C++ and designed for the Microsoft Windows operating organisation. A port of CT1 to Linux with Qt4 was started, but there is no progress anymore.[ix]

In 2007, development began on ii boosted projects, both based on a pure-plugin architecture, to serve equally successors to the original CrypTool program. Both successors regularly publish new stable versions:

  • CrypTool two [10] [xi] (built with C#/.Cyberspace/WPF) (abbreviated CT2)
uses the concept of visual programming to clarify cryptographic processes. Currently, CT2 contains more 150 crypto functions.

  • JCrypTool 1.0 [12] [13] (built with Java/Eclipse/RCP/SWT) (abbreviated JCT)
runs on Windows, macOS, and Linux, and offers both a document-centric and a function-axial perspective. Currently, JCT contains more than than 100 crypto functions. One of its focal points are modern digital signatures (similar Merkle trees and SPHINCS).

Awards [edit]

CrypTool has received several international awards every bit an educational programme, such equally the TeleTrusT Special Honour 2004, EISA 2004, It Security Award NRW 2004, and Selected Landmark in the Land of Ideas 2008 award.[fourteen]

Use [edit]

CrypTool is used in schools, universities,[15] companies and agencies for didactics and awareness training.[16] [17] [eighteen]

Worldwide, the CrypTool packages are downloaded more than than 10,000 times per month from the CrypTool website. But over l% of the downloads are for the English version.

CrypTool-Online (abbreviated CTO) [edit]

The CrypTool projection also includes the website CrypTool-Online,[19] launched in 2009. This website allows users to try cryptographic methods straight within a browser on a PC or on a smartphone (using JavaScript), without the need to download and install software. This site aims to nowadays the topic in an easy and attractive way for new users and young people.[20] Advanced tasks yet require the offline versions of CrypTool.

MysteryTwister (MTC3) [edit]

In 2010, the international nada competition MTC3 started as role of the CrypTool projection.[21] The contest currently offers more than 200 challenges derived from old and modernistic ciphers and designed by more thirty unlike authors from different countries. All challenges are presented in PDF templates in English and High german. The challenges are clustered in four levels of difficulty, which range from unproblematic riddles solvable with paper-and-pencil to mathematical challenges from modern cryptanalysis for researchers and experts. Additionally, a moderated forum, user statistics, and a hall-of-fame are bachelor. Currently, more than than 10,000 registered users are engaged in solving these challenges.

Merger with CrypTools [edit]

In early 2020, the CrypTool project decided to merge[22] with a similar project of the same name, CrypTools, founded in 2017 in Australia by Arthur Guiot, Lucas Gruwez and Luka Lafaye de Micheaux.[23] CrypTool, much older and known, thus completely "absorbs" the projection under its name.

Old logo, still used in CrypTool portal

The first bear on of this merger is the rebranding of the project. A new logo, a new website, and the new CTO version are announced. Currently, it'south still in development. Another change was the targeted audience. Previously, CrypTool focused on (university) students, and CrypTools on developers and young people. It was therefore necessary to broaden the audience.

On May 15, 2020, in the midst of the COVID-19 pandemic, CrypTool announces the creation of tools to test Decentralized contact tracing protocols.[24] A new page is added to CTO with technical description of the algorithms involved in DP-3T and Exposure Notification.[25] In add-on to this, CrypTool also announced the implementation of a folio dedicated to raising sensation of the cryptographic means related to privacy in these protocols, called the Corona Tracing Animation. The newer folio stands out for its new design and its accessibility to ordinary users.[24]
