This project is a simple command-line tool for encrypting and decrypting files using a symmetric key derived from a user-provided password. It leverages the cryptography library's Fernet implementation for secure encryption. File Encryption: Securely encrypts files using a password. File Decryption: Decrypts previously encrypted files using the correct password. Password-Derived Key: Generates a strong encryption key from the password using SHA-256 hashing.
