Let's start off by installing cryptography: pip3 install cryptography RELATED: How to Extract and Decrypt Chrome Cookies in Python. Note: It is important to understand the difference between encryption and hashing algorithms, in encryption, you can retrieve the original data once you have the key, wherein hashing functions, you cannot, that's why they're called one-way encryption.
There are a lot of encryption algorithms out there, the library we gonna use is built on top of the AES algorithm. We will be using symmetric encryption, which means the same key we used to encrypt data, is also usable for decryption.
In this tutorial, you will learn how to use Python to encrypt files or any byte object (also string objects) using the cryptography library. It is critically important because it allows you to securely protect data that you don't want anyone to see or access.
