Example sentences
Sloppy registrar-CAs would lose business because their trustworthyness actually means something for once.
It's actually slightly less horrifying at Namecheap, because as your registrar you should be using crazy good passwords anyways, which means they're never re-used.
With my suggestion, they couldn't, unless the rogue CA is actually the registrar, because the browser would see that the SSL certificate was not signed by the appropriate registrar.
Since Google Is now a domain registrar they could create the new domains on the fly.
You'd trust that single entity to inform the registrar anyway, so descentralizing it gains you nothing.
For end-users with a hijacked DNS, the registrar-issued SSL certificate would still protect the transmission, because the DNS-spoofing adversary would not be able to present a valid certificate signed by the registrar.
Maybe the system could be changed to one where domains can only be signed by the DNS registrar, or something.
True but if they're raintrees' registrar, they should already be able to connect the domain with the person/company who registered it.
You see, both of these processes are already mandatory based on other parts of the registrar-registrant relationship and existing legal requirements.
If the registrar is the only valid issuer of certificates, this loophole is closed since there is nothing for the CA to verify - the registrar already knows who the customer is and can offer certificate signing without an insecure DNS based domain validation.
They are my registrar, they host my DNS, including my MX record.
And it's a lot harder to block a registrar than a CA...
Quote examples
* Registrants of customer domain ("example.com", "example.org" etc) can request a domain-specific CA at their registrar, and only at their registrar.
You could create a DNS-style CA setup like this: * Browsers would ship with ONE root CA, the public key of the "." root zone operator * Each TLD ("com", "org" etc) has a CA signed by the root zone operator, valid only for signing TLD registrar CAs.
