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.

    // and provide timestamp server information.

    // 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 := chilkat.NewCert()

    // Yubico YubiKey OTP+FIDO+CCID 0, default PIN = 123456
    cert.SetSmartCardPin("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.
    exePath := "C:/someOtherDir/HelloWorld.exe"

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