This means that a CA could take the request for “issue a certificate to example.com <http://example.com/>”, do validation and key generation, throw away the private key, issue the cert, and end up with a “pre-validated” domain.  This is compliant.  The generated cert could have some flag in it, similar to a pre-cert, that makes it unusable for any real world purpose, and it would still be fine.  But this is silly.  We don’t want to have hoop jumping for no discernible value.

I would suggest a change myself, but I’m not quite clear which part of the BRs you feel prevents this today.

It makes sense if an organization comes to the CA, signs a contract that includes the subscriber agreement, then requests validation of domain and organization identities (because affiliates can be validated, it is possible there are multiple organization identities bound to a single applicant organization).  Then same organization comes back and request a certificate in the future.  There is no confusion about the Applicant.

There is no reason a CA couldn’t pull public records based on info in CT to help expedite things (for example identifying the company registration number), but the validation still has to happen. You can’t finalize the validation without binding it to a legal entity who will be the applicant/subscriber.  It is possible that this validation could use records pulled by the CA prior to the request for validation.

To further add to the extreme, it might be possible for the CA to pre-generate the public key, and just call up the subscriber and say "Do you want a cert" - with that assent being sufficient to constitute an “Application"

I would think that a valid application could be made via a phone call, especially if there is an existing subscriber agreement in place and the CA is expected to generate the key.

Thanks,
Peter
