Webcryptography 是一个python加密库. cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. 文档 cryptography.io 以前使用过很多不同的加密库，但pyhton界貌似没有一个统一的库。. 但需要用到RSA加密时用到一个库，需要AES时又要装另一个库，这对于库的使用和项目管理变得很不友好！

Did you know?

A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program. WebOne or more cryptographic primitives are often used to develop a more complex algorithm, called a cryptographic system, or cryptosystem. Cryptosystems (e.g., El-Gamal encryption ) are designed to provide particular functionality (e.g., public key encryption) while guaranteeing certain security properties (e.g., chosen-plaintext attack (CPA ...
