I saw that, if a particular domain for a certificate uses Technitium DNS, the infos are not exposed nor the API allows the user to modify it. Since the input/output object seems to already support almost all the available methods, I think it would be nice to also have this one implemented.
It should be relatively simple, if nobody's able to handle this isse I'm willing to work on it, but I need some guidance because I've never browsed this codebase.
