⚠️ Security Notes

• This repo is for educational purposes only.
• Key management is critical. If encryption_key.key is stolen, files can be decrypted.
• Use advanced key storage (HSM, vaults) in production.
• Add file integrity checks (MAC) for stronger protection.

See SECURITY.md for details.

🛠️ Improvements Roadmap

• Add password-based key derivation (PBKDF2 / Argon2).
• Add GUI (Tkinter / PyQt).
• Add drag-and-drop support.
• Integrate with cloud storage encryption.
