Authenticode Sign an Executable (EXE) or DLL

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL.

Note: Chilkat's code signing class was added in v9.5.0.97

C#

bool success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  First create the following JSON to specify that SHA256 is to be used,
//  and provide timestamp server information.

//  {
//    "hashAlg": "sha256",
//    "timestampToken": {
//      "enabled": true,
//      "tsaUrl": "http://timestamp.digicert.com",
//      "requestTsaCert": true,
//      "hashAlg": "sha256"
//    }
//  }

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateString("hashAlg","sha256");
json.UpdateBool("timestampToken.enabled",true);
json.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com");
json.UpdateBool("timestampToken.requestTsaCert",true);
json.UpdateString("timestampToken.hashAlg","sha256");

//  Load a code signing certificate..
Chilkat.Cert cert = new Chilkat.Cert();
success = cert.LoadPfxFile("C:/someDir/myCodeSigningCert.pfx","pfx password");
if (success == false) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

//  You can sign .exe or .dll files.
string exePath = "C:/someOtherDir/HelloWorld.exe";

Chilkat.CodeSign signer = new Chilkat.CodeSign();

//  If successful, the following call will apply the signature to the EXE (or DLL).
success = signer.AddSignature(exePath,cert,json);
if (success == false) {
    Debug.WriteLine(signer.LastErrorText);
    return;
}

Debug.WriteLine("Successfully applied the Authenticode signature.");
