Add a native full post-quantum encryption mode and fix a critical keystream-reuse bug in deduplicated encrypted archives. Full post-quantum mode (--pq-only) - New envelope type 0x06 (ZUPT_ENC_PQ_ONLY): ML-KEM-768 (FIPS 203) as the sole key-establishment mechanism, with no classical X25519 component. Archive key = SHA3-512(ml_ss || ml_ct || "ZUPT-PQ-ONLY-v1"). - For compliance postures that require a single NIST-standardised PQ primitive with no classical KEM in the envelope (CNSA 2.0-style "PQ-only"). Hybrid --pq stays the recommended default; --pq-only has no classical fallback, so a break of ML-KEM-768 alone breaks it. - keygen --pq-only / keygen --pub --pq-only (ZPQK magic, 1200B pub / 3600B priv; not interchangeable with hybrid --pq keys). Wrong or tampered ciphertext is rejected via ML-KEM FO implicit rejection plus the HMAC-SHA256 Encrypt-then-MAC envelope. In-tree, default build. Security (critical): AES-256-CTR keystream reuse under --dedup - Dedup assigns block sequence 0 to every data block (the sentinel that keeps cross-file dedup references authenticating consistently). The per-block nonce was base_nonce XOR block_seq, so under --dedup every block collapsed to the same nonce, reusing the CTR keystream across distinct plaintexts (a many-time-pad). Each block now uses a fresh random 128-bit nonce stored in the block prefix and bound into the block MAC; block_seq is still bound as MAC AAD. Regression test: tests/test_dedup_nonce.sh. Re-encrypt any --dedup encrypted archives written by <= 4.1.0. Other - keygen --sdk / --box on a source-only build now fails with a clear message pointing to native --pq / --pq-only (or a WITH_SDK=1 build). - Documentation: README, SECURITY, THREAT_MODEL, man page, CHANGELOG, and all packaging recipes updated for the new mode and the security fix; version bumped to 4.2.0. Wire format v1.6 unchanged (0x06 is additive). Validation: make check 16/16, quick suite 11/11 (incl. PQ-only), dedup-nonce regression (all block nonces distinct), cppcheck clean. |

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 |
