4. Enter the decryption key: "secretkey123" Output value: The program decrypts the file "test_encrypted.txt" using the provided decryption key "secretkey123" and saves the decrypted version as "document_decrypted.txt". Solution: Using Fernet (Symmetric Encryption with Cryptography Library) Code:...
This paper aims to explore the current file encryption technology in the field of data security and proposes a file encryption digital system based on Python. Firstly, an overview of file encryption technology is provided, and a brief introduction to digital encryption algorithms and Python encryption...

Now you know how to basically encrypt strings, let's dive into file encryption; we need a function to encrypt a file given the name of the file and key: def encrypt(filename, key): """ Given a filename (str) and key (bytes), it encrypts the file and write it """ f = Fernet...
