Install it via pip:pip install cryptography
🧠 How the System Works 🔐 Encryption Process: User selects a file via the GUI.
AES key is auto-generated (or loaded from secret.key).
The file is read as binary, encrypted using Fernet (AES-256 under the hood).
An encrypted copy is saved with .enc extension.
A SHA256 hash of the original file is computed and logged for integrity.
Original file remains untouched unless configured otherwise.
🔓 Decryption Process: User selects a .enc file.
The encryption key from secret.key is loaded.
The file is decrypted back into its original binary content.
The user chooses where to save the decrypted file (e.g., mydoc.pdf).
A new SHA256 hash is logged for verification.
🖼️ Interface Preview (Optional) Add a screenshot of the GUI here if you'd like.
📁 Output Files secret.key → Encryption key (keep this safe!)
file.enc → Encrypted file
decrypted_file → Decrypted output (you choose name/location)
file_log.txt → Log of actions with timestamps and SHA256 hashes
