Dialog 'Encryption Wizard'

Function: The wizard makes sure that a certificate for the encryption of downloads, online changes, and boot applications is downloaded from the controller. If a valid certificate does not exist on the controller for this purpose, then the wizard makes sure that a certificate is created. Changes to the application on the controller (download, online change, boot application) are possible only when this certificate exists.

Details

Description of the individual actions of the wizard with corresponding notices in the case of failures

Start

If the connection path to the controller is set correctly in the device editor, then the wizard starts the necessary actions for encrypting downloads, online changes, and boot applications with a certificate.

If an expired certificate exists, then a corresponding warning is displayed with a dialog prompt whether or not a new certificate should be created by the controller. When this is confirmed, the new certificate is created and loaded to the local Certificate Store. In this case, the existing boot application may not start anymore and must be created again with the new certificate.

The Certificate Settings dialog opens when a new certificate is to be created on the device. Here you configure the Key length (bit) and the Validity period (days) for the certificate.
