The AssureOwnCertificate methods check if the application has its own application certificate (according to application configuration), and create the certificate if it is missing.

If the own certificate does not exist in the certificate store prior to the operation, the method creates it. Otherwise, the method also checks whether the instance certificate is present in the trusted peers certificate store, and if it is absent, it copies it there. This is in contrast to the CreateOwnCertificate method, which always creates a new certificate when successful.
