Version bump to 5.2.1. Docs: 'What's new in 5.2.1', a refreshed Compression
comparison section (ratio + throughput vs zstd/gzip/lz4 on codec 2.65.3, all
round-trips byte-exact) and a new Audit status table (make check 16/16, FIPS 203
3/3, the full security regression matrix). Packaging versions bumped. (The GUI

VaptVupt GUI
Desktop application for vaptvupt backup compression with ML-KEM-768 + X25519 post-quantum hybrid encryption.
Works on GNU/Linux, BSD, macOS, and Windows.
Install
Linux (recommended)
tar xzf vaptvupt-gui.tar.gz && cd vaptvupt-gui
./vaptvupt-gui # auto-creates venv, installs PySide6
./install.sh --user # adds right-click menu integration
Windows
Option A — Installer (recommended):
Download VaptVuptGUI-1.3.0-Setup.exe and run it. Installs to Program Files, adds Start Menu shortcut, desktop shortcut, right-click context menus, and .zupt file association. Includes uninstaller.
Option B — Build from source:
cd packaging\windows
build-windows.bat
Requires Python 3.9+, NSIS 3.x, and a compiled vaptvupt.exe.
Option C — Run directly:
pip install PySide6
python src\zupt_gui.py
macOS / BSD
pip3 install PySide6
python3 src/zupt_gui.py
AppImage (universal Linux)
chmod +x VaptVupt-GUI-1.3.0-x86_64.AppImage
./VaptVupt-GUI-1.3.0-x86_64.AppImage
Flatpak
flatpak-builder --install build packaging/flatpak/dev.zupt.gui.yml
flatpak run dev.zupt.gui
Features
| Tab | Function |
|---|---|
| Keys | Generate ML-KEM-768 + X25519 hybrid keypairs |
| Compress | All codecs, levels 1-9, dedup, solid, password, PQ keys |
| Extract | Decrypt and extract .zupt archives |
| Verify | Check block checksums, view archive metadata |

Linux (Nemo / Cinnamon)
After ./install.sh --user:
- Right-click any file: Compress with VaptVupt
- Right-click .zupt file: Extract with VaptVupt
- Double-click .zupt: opens in VaptVupt GUI
Windows (after installer)
- Right-click any file: Compress with VaptVupt
- Right-click any folder: Compress with VaptVupt
- Double-click .zupt: opens in VaptVupt GUI
- Right-click .zupt: Verify Integrity
