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.

Go

    success := false

    // 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"
    //   }
    // }

    json := chilkat.NewJsonObject()
    json.UpdateString("hashAlg","sha256")
    json.UpdateBool("timestampToken.enabled",true)
    json.UpdateString("timestampToken.tsaUrl","http://timestamp.digicert.com")
    json.UpdateBool("timestampToken.requestTsaCert",true)
    json.UpdateString("timestampToken.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 := chilkat.NewCert()

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

    // Load the certificate based on the serial number.
    // *** Use your certificate's serial number.
    success = cert.LoadFromSmartcard("serial=3FF5B69109BFD4046C92CC0D18EE23C2")
    if success == false {
        fmt.Println(cert.LastErrorText())
        json.DisposeJsonObject()
        cert.DisposeCert()
        return
    }

    // 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.
    exePath := "C:/someDirectory/HelloWorld.exe"

    signer := chilkat.NewCodeSign()

    // If successful, the following call will apply the signature to the EXE (or DLL).
    success = signer.AddSignature(exePath,cert,json)
    if success == false {
        fmt.Println(signer.LastErrorText())
        json.DisposeJsonObject()
        cert.DisposeCert()
        signer.DisposeCodeSign()
        return
    }

    fmt.Println("Successfully applied the Authenticode signature.")
