<h1 align="center">CryptUISharp</h1> <p align="center">Managed APIs and WinUI surfaces for Authenticode, catalog signatures, certificates, and advanced signature fields.</p>

Status

This is an early prototype rebuilt around the CryptUISharp library in this repository.

The app currently reads:

  • embedded Authenticode / PKCS#7 signatures
  • catalog-signed files via system catalog lookup
  • .cat files as catalog CTLs
  • signer certificates and chains
  • signing time, timestamp, digest, and signature algorithms
  • authenticated, unauthenticated, countersignature, timestamp, and catalog entry fields

Usage

  1. Build and run the WinUI project.
  2. Open a file with the button or drop a file onto the window.
  3. Select a signature, catalog, or catalog entry to inspect the corresponding details.

Build

Prerequisites:

  • Windows 10 build 17763 or later, or Windows 11
  • .NET 9 SDK or newer
  • Windows App SDK workload/runtime suitable for WinUI 3
dotnet build .\CryptUISharp.slnx -p:Platform=x64

Project Layout

  • CryptUISharp: Windows CryptoAPI / WinTrust library packaged as CryptUISharp.
  • CryptUISharp.WinUI: WinUI 3 app that presents the library model.

The catalog path follows the old cryptui dialog model: catalog files are CTLs, entries come from CTL_INFO.rgCTLEntry, and known entry attributes such as SPC_INDIRECT_DATA_OBJID and CAT_NAMEVALUE_OBJID are decoded when present.
