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.

一个现代、高速、易用的面向对象 C++ 密码库，旨在利用 C++ 的面向对象特性简化使用步骤，同时使密码算法模块化、让不同密码算法具有统一的接口，从而提升实现时的便捷性（易扩展性）和使用的灵活性。

算法经过高度优化（同时保证了可读性），多种算法运行效率超过 OpenSSL 等经典密码库。
