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

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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"
  //   }
  // }

  final json = CkJsonObject();
  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..
  final cert = CkCert();
  try {
    cert.loadPfxFile('C:/someDir/myCodeSigningCert.pfx', 'pfx password');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

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

  final signer = CkCodeSign();

  // If successful, the following call will apply the signature to the EXE (or DLL).
  try {
    signer.addSignature(exePath, cert, json);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Successfully applied the Authenticode signature.');
