AUTOCRYPT HOMMORPHIC SOFTWARE
AUTOCRYPT HOMMORPHIC FREE

In addition to the algorithms, solvers (analyzers) are included, especially for classical ciphers. 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.

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.

AUTOCRYPT HOMMORPHIC SOFTWARE

To introduce users to the field of cryptography, the organization created multiple graphical interface software containing an online documentation, analytic tools and algorithms. Users can adjust these with own parameters. ĬrypTool implements more than 400 algorithms.
