Shadow Protocol — SHADOW_PROTOCOL_ENCRYPTOR

⚠️ Quick start (Windows PowerShell)

1. Install Python 3.8+ (recommended 3.10+).
2. Open PowerShell in the project folder (where app.py lives).
3. Create and activate a virtual environment:

python -m venv .venv
.\.venv\Scripts\Activate.ps1

If activation fails due to execution policy, run as administrator or:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

4. Install dependencies:

pip install streamlit

(Optionally create a requirements.txt with streamlit for reproducibility.)

5. Run the app:

streamlit run app.py

6. Open your browser at: http://localhost:8501 (Streamlit prints the exact URL in the terminal).

What this app does

• A simple Streamlit UI that hides text inside zero-width Unicode characters (steganography).
• Use the left panel to "inject" (encrypt) a hidden payload into a visible cover string (e.g., emojis).
• Use the right panel to paste intercepted data and attempt decryption.

Notes & Tips

• The app uses a Google font (Fira Code) via a remote import — an internet connection is required for that styling to load.
• Stop the server with Ctrl+C in the terminal running Streamlit.
• Tested on Windows with Streamlit; behavior should be the same on macOS/Linux.

Security & License

• This is an educational tool. Be careful with real sensitive data — use at your own risk.
• No license specified. Add a LICENSE file if you plan to publish or share.

If you'd like, I can also add a requirements.txt and a small LICENSE for you. ✅
