Encrypt File

A small desktop tool to encrypt and decrypt files with a key you control. Pick files, load or generate a key, click Encrypt or Decrypt. Nothing leaves your computer.

Features

• Select several files at once
• Generate a new key file, or load one you saved before
• Choose where each encrypted or decrypted copy is saved
• Symmetric encryption (Fernet from the cryptography library)

How to use

1. Click Generate Key and save the .key file somewhere safe, or Load Key to use an existing one.
2. Click Load File and pick one or more files.
3. Click Encrypt File or Decrypt File, then choose the name and folder for each result.

⚠️ Keep your key safe. Lose it and the encrypted files cannot be opened. Anyone with the key can open them. Test with a non-important file first.

If decryption fails (for example the wrong key), an error is printed in the console.

Run from source

Python 3 with Tkinter (included in the standard Windows installer).

pip install -r requirements.txt
python encrypt.py
