RELATED: How to Extract and Decrypt Chrome Cookies in Python. 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. Note: It is important to understand the difference between encryption and hashing algorithms. However, there are malicious uses of encryption, such as building ransomware we have a tutorial on how to build such a tool. In fact, if you're reading this, then your browser is securely connected to this website (i.e., encryption).
There are many encryption uses in the real world. The library we gonna use is built on top of the AES algorithm. There are a lot of encryption algorithms out there. We will use 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.
