HashTabGen

HashTabGen is a Windows Explorer Property Sheet shell extension that computes and displays multiple file hashes in the file properties dialog.

This repository currently contains:

• HashTabGen (DLL shell extension, ATL/COM, Visual Studio project)
• HashTabInstaller (console installer/uninstaller for registry registration)

Features

• Hash tab in file properties
• Multiple algorithms (Crypto++ + custom implementations where needed)
• Hash list, copy actions, save to file
• Per-user settings in registry (HKCU\\Software\\HashTabGen)
• Async hashing with progress bar

Build Requirements

• Visual Studio 2022 (C++ Desktop workload)
• Windows SDK
• Initialized crypt++ submodule
• Crypto++ static library (cryptlib.lib) built for required configs:
  • crypt++\\x64\\Output\\Debug
  • crypt++\\x64\\Output\\Release
  • crypt++\\Win32\\Output\\Debug
  • crypt++\\Win32\\Output\\Release

Build

1. Initialize submodules:
   • git submodule update --init --recursive
2. Build Crypto++ first (crypt++\\cryptlib.vcxproj) for required configurations:
   • Debug|Win32, Release|Win32, Debug|x64, Release|x64
3. Verify output libraries exist in:
   • crypt++\\Win32\\Output\\Debug\\cryptlib.lib
   • crypt++\\Win32\\Output\\Release\\cryptlib.lib
   • crypt++\\x64\\Output\\Debug\\cryptlib.lib
   • crypt++\\x64\\Output\\Release\\cryptlib.lib
4. Open HashTabGen.sln in Visual Studio.
5. Select configuration (Debug/Release) and platform (Win32/x64).
6. Build solution.

Install / Uninstall

Run HashTabInstaller.exe as Administrator and follow prompts.
