The device will be produced with a signature certificate and a HTTPs certificate. Both manufacture certificates are self signed certificate which are signed by the StepOver Root Certificates. To avoid error messages by the browser because of a insecure connection and to get the green tick when checking the signatures with Adobe Reader you need to install the StepOver Hardware Root and the Intermediate certificates.
