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

    // 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",

    // Load a code signing certificate..

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