Authenticode Sign using Smartcard or USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a smartcard or USB token, such as a Yubikey.

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",
//     "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.

// Assuming you have the Yubikey inserted into the USB on the computer...
// and there is only 1 signing certificate on the Yubikey, then just load from
// the "smartcard".  (assuming you don't have additional smartcards or USB tokens plugged in)

// If the smartcard/token has several possible certificates that can be used for signing,
// then see the online documentation for the LoadFromSmartcard method,
// and also see the online documentation and examples for Chilkat Pkcs11 and ScMinidriver.
// There are many possible ways to load a Chilkat certificate object with a cert (and associated private key)
// from a variety of sources.  The only coding difference for any signing function in Chilkat,
// whether it be a PDF, XmlDSig, CMS, etc. is in how the cert is loaded.

// You can sign .exe or .dll files.
