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.

//  Yubico YubiKey OTP+FIDO+CCID 0, default PIN = 123456

//  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.
