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).

Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys to provide equivalent security, compared to cryptosystems based on modular exponentiation in Galois fields, such as the RSA cryptosystem and ElGamal cryptosystem.
In cryptography, the ElGamal encryption system is an asymmetric key encryption algorithm for public-key cryptography which is based on the Diffie–Hellman key exchange.It was described by Taher Elgamal in 1985. [1]
As member of the teaching staff at the Eichendorffschule in Kelkheim near Frankfurt I can tll we use CrypTool x-software 2 for nine years at special workshops. I can confirm on behalf of our school that CT is an open-source-software, has a very good and supportive community, and works fine in our courses on cryptography.
