That CrypTool was originally designed as an internal business application for information security training. CrypTool has since developed into an important open-source project in the field of cryptology. Over 50 volunteer developers worldwide contribute to the program.

What is CrypTool 1

CrypTool 1 (CT1) is an open-source Windows program for cryptography and cryptanalysis. It’s the most wide-spreaded e-learning software of its kind.

What is CrypTool 2?

CrypTool 2 (CT2) is an open-source program offering an innovative visual programming GUI to experiment with cryptographic procedures and to animate their cascades.

What is JCrypTool?

JCrypTool (JCT) is an open-source e-learning platform, allowing to experiment comprehensively with cryptography on Linux, MAC OS X, and Windows.

What is CrypTool-Online?

CrypTool-Online (CTO) runs in a browser and provides a huge variety of encryption methods and analysis tools including many illustrated examples.

What is MysteryTwister C3?

MysteryTwister C3 (MTC3) is an international Crypto Cipher Contest offering a broad variety of challenges, a moderated forum and an ongoing hall-of-fame.

On 1st of June 2015 the first of 6 tasks starts on the Enigma level. For three weeks two times per week new documents with tasks are published.

Most important is the time that you need for the final task. Notes, time bonuses and "cryptologic bombs" help to solve the tasks. For non-expertsthere are also two easier levels.

"During the game everyone can find out what methods were used to beat Enigma as well as try to break messages encoded with the famous machine cipher. Enigma, a cipher machine considered unbreakable, was defeated by three brilliant mathematicians. Now, together with other adventurers from around the world, you have a chance to become an Enigma codebreaker."

Team with three people can join worldwide. Registration under www.codebreakers.eu
