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.

// 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"
//   }

// 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.
cert := CkCert_Create();

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

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

// 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.
