Python: File Encryption and Decryption

This Python snippet encrypts and decrypts files to secure sensitive information using the 'cryptography' library. It's designed for security-conscious users or organizations that need to protect data from unauthorized access.

The snippet provides strong encryption for files, making it suitable for securing documents, backups, and other sensitive data. This functionality is crucial for maintaining privacy and security in data storage and transmission.

Using 'cryptography', the code encrypts files with a secure key and allows for their safe decryption only when the correct key is provided. This process ensures data integrity and protection against potential security breaches.

This tool is essential for enhancing data security in applications that handle or store sensitive or confidential information, providing a robust solution for encryption needs.

Below is the complete code for file encryption and decryption, a critical component for securing data in various applications.
