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.

// and provide timestamp server information.

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

// 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.

// It will be a string similar to this:  j6X54nB7-jlp5Cr2

// to login to your token using your token password.
// You don't want too many failed logins, otherwise you'll lock the token.
