Code Signing using Sectigo USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a SafeNet USB token from Sectigo.

Requires Chilkat v10.0.0 or greater.

    try {
        System.loadLibrary("chilkat");

    // 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",

    //     "hashAlg": "sha256"
    //   }

    json.UpdateBool("timestampToken.requestTsaCert",true);
    json.UpdateString("timestampToken.hashAlg","sha256");

    // The only difference in signing with a smartcard or USB token
    // is that the cert is loaded from a smartcard or USB token, instead of a PFX or from elsewhere
    // such as from the Windows certificate store.
    CkCert cert = new CkCert();

    // Use your USB token PIN (user password).
    // It will be a string similar to this:  j6X54nB7-jlp5Cr2
    cert.put_SmartCardPin("j6X54nB7-jlp5Cr2");

    // Load the certificate based on the serial number.
    // *** Use your certificate's serial number.

        return;
        }

    // Note: If the above fails, then use the SafeNet Authentication Client Tools
    // to login to your token using your token password.
    // You don't want too many failed logins, otherwise you'll lock the token.
    // A successful login will reset number of failed logins back to 0.

    // Note: This is to sign Microsoft Windows executables or DLLs
    // You can sign .exe or .dll files.
    String exePath = "C:/someDirectory/HelloWorld.exe";

    CkCodeSign signer = new CkCodeSign();

    // If successful, the following call will apply the signature to the EXE (or DLL).
