CrypTool is an open-source project[1] that is a free e-learning software for illustrating cryptographic and cryptanalytic concepts. According to "Hakin9",[2] CrypTool is worldwide the most widespread e-learning software in the field of cryptology.[3][4]
CrypTool implements more than 400 algorithms.[5] Users can adjust these with own parameters. To introduce 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, as well as modern symmetric and asymmetric cryptography including RSA, ECC, digital signatures, hybrid encryption, homomorphic encryption, and Diffie–Hellman key exchange. Methods from the area of quantum cryptography (like BB84 key exchange protocol) and the area of post-quantum 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 addition it contains: didactical games (like Number Shark, Divider Game, or Zudo-Ku) and interactive tutorials about primes, elementary number theory, and lattice-based cryptography.
