But DV isn't the only kind of validation I'd like to be supported here. I'd like if it were possible to extend that to include cases where one has control over the web server, but not the DNS. Now there are dangers in that so I'm not sure if it's really doable, but I've controlled web servers below tcd.ie for years (e.g. [1]), without any control over DNS, and I'd like to be able to do better than self-signed out of the box there too. The current spec [2] seems to allow for that via the "provision a file on the web server" method, but the details of that ("simpleHttps" I guess?) aren't clear. I'm also not sure of the security implications, which could be a killer (for having key authorization depend on this mechanism alone) so I'm sure there's work to be done there. But I'd very much like to just update apache on my servers and have that go get certs that work. S.
