WinTrustSharp

Lightweight .NET interop for validating Windows Authenticode (code-signing) signatures on PE files (EXE/DLL).

WinTrustSharp_Tests
  Tests in group: 13
   Total Duration: 41 ms

Outcomes
   13 Passed

Features

  • Verify: Check if a file has a valid Authenticode signature. If the file was tampered with after signing, this will return false since the digital signature is no longer valid.
  • VerifyFull: Validate both the signature and the signing certificate chain.
  • Custom Policy: Supply your own X509Chain policy for revocation checks, extra roots, etc.
  • Thread-safe and dependency-free (just P/Invoke to wintrust.dll).

Install

Get it on NuGet!

# Package Id
WinTrustSharp

# dotnet CLI
dotnet add package WinTrustSharp

# Package Manager
Install-Package WinTrustSharp

Usage

using System.IO;
using WinTrustSharp;

// Digital signature check only
bool validDigitalSignature = Authenticode.Verify(new FileInfo("SomeLibrary.dll"));

// Full validation (certificate trust + signature structure)
bool trusted = Authenticode.VerifyFull("SomeLibrary.dll");

Custom certificate validation

using System.Security.Cryptography.X509Certificates;

bool ok = Authenticode.VerifyFull("SomeLibrary.dll", (cert, chain) =>
{
    chain.ChainPolicy.RevocationMode = X509RevocationMode.Online;
    return chain.Build(cert);
});

Notes

  • Windows only (wintrust.dll interop).
  • Verify works for embedded or catalog signatures.
  • VerifyFull requires an embedded signature (throws if unsigned or catalog-only).
  • Revocation checks are not automatic—configure them via X509Chain if needed.
