CT1 is a freeware program which enables you to apply and analyze cryptographic mechanisms. It has the typical look-and-feel of a Windows application. CT1 contains comprehensive online help, which can be understood without deep knowledge of cryptography. CT1 is available in English, German, Polish, Spanish, and Serbian. CT1 includes every state-of-the-art cryptographic function and allows you to learn about and use different cryptographic methods within the same environment.
The algorithms available include both classic and modern cryptosystems:
- classic methods: the Caesar cipher, the ADFGVX cipher, the double-column transposition (permutation), the Enigma encryption algorithm, etc.
- modern methods: the RSA and AES algorithms, hybrid encryption, algorithms based on lattice reduction and elliptic curves, etc.
