The current version of CrypTool is used all over the world. It supports both contemporary teaching methods at schools and universities as well as awareness training for employees and civil servants.

The current version offers beside others the following highlights:

* Numerous classic and modern cryptographic algorithms (encryption and decryption, key generation, secure passwords, authentication, secure protocols, ...)
* Visualisation of several methods (e.g. Caesar, Enigma, RSA, Diffie-Hellman, digital signatures, AES)
* Cryptanalysis of certain algorithms (e.g. Vigenère, RSA, AES)
* Crypt-analytical measuring methods (e.g. entropy, n-grams, autocorrelation)
* Auxiliary methods (e.g. primality tests, factorisation, base64 coding)
* Tutorial about number theory
* Comprehensive online help
* Supportive script with further information about cryptology

From its original use of information security training for a company, CrypTool has developed into an outstanding open source project for cryptology related topics.
