VaptVupt GUI — Cross-Platform Post-Quantum Backup

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

After install, right-click any file in Nemo/Nautilus to see "Compress with VaptVupt". Double-click any .zupt file to open it in the GUI.

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

Architecture

VaptVupt GUI (PySide6, Python)
    |
    |-- subprocess.Popen() with streaming stderr
    |
    v
vaptvupt CLI (Pure C11 binary)
    ML-KEM-768 + X25519 + AES-256-CTR
    VaptVupt / LZHP / Store codecs
    Block deduplication, full-disk backup

The GUI calls the vaptvupt CLI binary — all cryptography runs in native C, not Python.
