zupt/gui/README.md
Cristian Cezar Moisés 5050570b23 v5.0.0: version bump, audit fixes, documentation overhaul
Version bumped to 5.0.0 across include/zupt.h, all packaging recipes, man
page, and docs.

Audit fixes (pre-5.0.0 review):
- src/zupt_format.c: overflow-safe bound in the solid-mode `test` path
  (off+sz could wrap and drive an OOB read in zupt_xxh64 on a crafted archive;
  the extract path was already hardened, the test path was not).
- gui: run_async now marshals the completion callback onto the GUI thread with
  QueuedConnection (a bare functor connected DirectConnection and touched
  widgets off the worker thread); Extract auto-detect note survives the log
  clear via a new `info` param.
- .github/workflows/ci.yml: trigger on `master` (was main/develop, so CI never
  ran); `make dist` tarball is vaptvupt-*.tar.gz not zupt-*; the ASAN PQ
  round-trip uses native --pq (was --pq-sdk, which fails on the source-only
  build and blocked the release job).

Documentation:
- New AUDIT.md (methodology, FIPS 203 conformance validation, findings, repro).
- CHANGELOG 5.0.0 entry covers the FIPS 203 conformance fix + BREAKING note and
  the GUI/CLI/security/packaging work.
- README "What's new in 5.0.0", download tables (incl. Windows/macOS/BSD +
  portable GUI), version-history row.
- SECURITY.md + THREAT_MODEL.md: ML-KEM-768 documented as FIPS 203, validated
  byte-for-byte against OpenSSL 3.5.
- Accuracy fixes: man page (--kdf default is PBKDF2 on source-only; codec
  2.60.4), rpm %description, debian control/copyright, homebrew header
  (no vendored library on source-only builds).

make check 16/16 (FIPS 203 conformance 3/3, all distro-safe checks).

# VaptVupt GUI
Desktop application for [vaptvupt](https://git.securityops.co/cristiancmoises/vaptvupt) backup compression with ML-KEM-768 + X25519 post-quantum hybrid encryption.
Works on GNU/Linux, BSD, macOS, and Windows.
## Install
### Linux (recommended)
```bash
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:**
```cmd
cd packaging\windows
build-windows.bat
```
Requires Python 3.9+, NSIS 3.x, and a compiled `vaptvupt.exe`.
**Option C — Run directly:**
```cmd
pip install PySide6
python src\zupt_gui.py
```
### macOS / BSD
```bash
pip3 install PySide6
python3 src/zupt_gui.py
```
### AppImage (universal Linux)
```bash
chmod +x VaptVupt-GUI-1.3.0-x86_64.AppImage
./VaptVupt-GUI-1.3.0-x86_64.AppImage
```
### Flatpak
```bash
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 |
| Disk | Full-disk backup and restore |
| About | Version, cryptographic stack, credits |
All tabs support drag-and-drop. Drop a .zupt file anywhere on the window to extract it. Drop any other file to compress it.
## System Integration
### 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**
## 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.
## Packaging
| Platform | Format | Tool |
|----------|--------|------|
| Any | pip | `pip install .` |
| Debian/Ubuntu/Mint | .deb | `packaging/deb/control` |
| Fedora/RHEL | .rpm | `rpmbuild -ba packaging/rpm/vaptvupt.spec` |
| Universal Linux | .AppImage | `packaging/appimage/build-appimage.sh` |
| Sandboxed Linux | .flatpak | `packaging/flatpak/dev.zupt.gui.yml` |
| Windows | .exe installer | `packaging/windows/build-windows.bat` |
| Windows | NSIS .exe | `packaging/windows/zupt-installer.nsi` |
