    --windowed \
    --icon ssh_encryptor/assets/icon.icns \
    --add-data "ssh_encryptor/assets:assets" \
    run.py

🪟 Windows (.exe)

    pyinstaller ^
    --onefile ^
    --windowed ^
    --icon ssh_encryptor/assets/icon.ico ^
    --add-data "ssh_encryptor\\assets;assets" ^
    run.py

🐧 Linux (binary or AppImage)

    pyinstaller \
    --name CryptoEngine \
