A modern, high-speed, easy-to-use object-oriented C++ cryptographic library, which aims to use the object-oriented features of C++ to simplify the steps of using, and make cryptographic algorithms modular, so that different cryptographic algorithms have a unified interface, thereby improving the convenience of implementation (scalability) and flexibility of use.

Algorithms are highly optimized (while ensuring readability), and several algorithms run more efficiently than classic cryptographic libraries such as OpenSSL.
