Encrypting and decrypting information with cryptography

In this section, we will review the cryptography module for encrypting and decrypting data, with algorithms such as AES.

Introduction to the cryptography module

The cryptography (https://pypi.org/project/cryptography) Python module is available in the PyPI repository. Use pip to install it:

$ pip install cryptography

The main advantage that cryptography provides over other cryptography modules such as pycryptodome is that it offers superior performance when it comes to performing cryptographic operations.

This module includes both high-level and low-level interfaces for common cryptographic algorithms, such as symmetric ciphers, message digests, and key-derivation functions. For example, we can use symmetric encryption with the fernet package.
