VPack Archiver v2.0.1

🗁 VPack Archiver v2.0.1 · Universal Archive Manager

Modern, ultra-fast universal archive manager, compressor, and WinRAR/7-Zip equivalent for .vpack archives built with 100% pure Rust.

✨ What's New in v2.0.1

• 🔐 Interactive GUI Password Handling:
  • Added modal password dialog prompt in vpack-gui.exe when opening, listing, testing, or extracting encrypted .vpack archives.
  • Cached credentials within active GUI session to avoid repeated prompts during multi-file operations.
• 🛡️ Core Archive Security & Path Traversal Fix:
  • Implemented Zip Slip path traversal mitigation (sanitize_archive_path), rejecting malicious path prefixes (../, ..\, absolute paths).
  • Fixed underflow boundary check in RFC 8032 Ed25519 signature validation.
  • Enabled full digital signature verification inside integrity test mode (vpack t).
• 🪟 Windows Runtime & TUI Stability:
  • Fixed CRT access violation (STATUS_ACCESS_VIOLATION / 0xc0000005) in WinRAR console explorer by migrating to pure-Rust UTC timestamp parsing.
• 🚀 Engine & Container Metadata Enhancements:
  • Fixed container header metadata update slices for file and byte totals across compress/append.
  • Added support for stored uncompressed codec (-C store).
  • Added WebView2Loader.dll bundling in native .vpack distributions for complete standalone offline execution.

🚀 Installation & Update Guide

📥 How to Install (New Users)

Option 1: One-Click Rust Installer (Recommended)

1. Download vpack-installer.exe and vpack-archiver-v2.0.1-windows-x86_64.vpack into the same folder (e.g. Downloads).
2. Run the installer:

.\vpack-installer.exe

Or install unattended / silently with all defaults (sets PATH, desktop shortcuts, and .vpack file associations):

.\vpack-installer.exe --silent

Destination: %LOCALAPPDATA%\Programs\VPack (or custom path via -d C:\Custom\Path).

Option 2: Portable ZIP Extraction

1. Download vpack-archiver-v2.0.1-windows-x86_64.zip.
2. Extract to your desired directory:

Expand-Archive -Path .\vpack-archiver-v2.0.1-windows-x86_64.zip -DestinationPath C:\Tools\VPack

3. Add to your User PATH (optional):

[Environment]::SetEnvironmentVariable("PATH", "C:\Tools\VPack;" + [Environment]::GetEnvironmentVariable("PATH", "User"), "User")

Option 3: Extract via VPack CLI (Dog-Fooding)

vpack x vpack-archiver-v2.0.1-windows-x86_64.vpack -o ./vpack

---

🔄 How to Update (Existing Users)

Upgrading to v2.0.1 is non-destructive — your existing shell shortcuts, context menus, and configurations will be preserved:

Method A: Upgrade via One-Click Installer (Fastest)

1. Close any running instances of VPack Archiver GUI or command line processes.
2. Download the latest vpack-installer.exe and vpack-archiver-v2.0.1-windows-x86_64.vpack.
3. Run the installer in silent mode to update in-place:

.\vpack-installer.exe --silent

The installer automatically replaces existing binaries in %LOCALAPPDATA%\Programs\VPack with the new version.

Method B: Direct In-Place CLI Upgrade

If vpack is already in your PATH, simply unpack the new .vpack archive directly into your installation directory:

# In-place overwrite for default install:
vpack x .\vpack-archiver-v2.0.1-windows-x86_64.vpack -o "$env:LOCALAPPDATA\Programs\VPack"

# Verify upgrade:
vpack --version

Method C: Update Portable ZIP

Extract vpack-archiver-v2.0.1-windows-x86_64.zip over your existing portable directory, choosing to overwrite existing files:

Expand-Archive -Path .\vpack-archiver-v2.0.1-windows-x86_64.zip -DestinationPath C:\Tools\VPack -Force
