Alec Muffet just said that the .onion RFC is about to be approved over at IETF.
https://datatracker.ietf.org/doc/draft-ietf-dnsop-onion-tld/ballot/
(It just passed the IESG review.)
It seems like there’s still not clear agreement within IETF about what procedure should be followed for doing things like this in the future. You can see some of the IESG members are not sure how good a model this is for the future. This registration was done pursuant to an earlier process that was created by RFC, and it’s brought into the open a fair amount of uncertainty about that process.
Congratulations to the authors of the RFC, and thanks to the authors of the earlier P2P Names Internet-Draft. I hope this leads the CA/B Forum to agree that it’s appropriate for CAs to issue certs for .onion names in the long run.
