OEM certificates should only be used in a secure environment

Since generating an OEM application license requires handling of the OEM certificate and its password, the process should only be carried out in an environment that is protected against malicious software (protected PC), in order to prevent the password for the OEM private key being accessed by malicious software.

The manual signing of a License Request File, and thus the creation of a License Response File, is done in the TwinCAT Engineering in the Software protection configurator.

1. Select the OEM certificate in the Certificates tab.
