This tutorial details how to use the fernet module in Python's cryptography library to implement file encryption and decryption operations. The article will cover the generation, management and reuse of Fernet keys, as well as how to securely perform encryption and decryption processes in files, and emphasize the importance of secure storage of keys to ensure data confidentiality.

How to encrypt and decrypt files in Python

26 Nov 2025

Fernet using the cryptography library can safely implement Python file encryption and decryption. 2. Generate and securely store keys for encryption and decryption processes. 3. When encrypting, read the file content and write it into the .enc file, and when decrypting, restore the original file. 4. Pay attention to key security management and avoid hard coding or submitting to version control. 5.Fernet is based on AES and HMAC and is suitable for most scenarios, but streaming processing of large files needs to be considered.
