Cryptography
This project is a Python cryptography library that provides a collection of cryptographic primitives and high-level recipes for implementing secure encryption and authentication. It functions as a symmetric encryption toolkit and a cryptographic hash provider, offering both a low-level cryptographic interface for building custom protocols and high-level tools for securing data.
The library covers a broad range of security capabilities, including symmetric data encryption, the derivation of cryptographic keys from passwords or secret values, and data integrity verification through the generation of message digests. It allows for the implementation of cryptographic primitives to facilitate secure authentication and encryption tasks.
