[TLS] Why TLSA RR and not CERT RR?

2022-06-26 Thread Robert Moskowitz
Recently I have been in a discussion about DNS RR that hold X.509 certificates. I am asking this here, as I *Think* there may be some knowledge here without me joining other lists... I was aware of DANE's rfc6698 that holds both X.509 certs or SubjectPublicKeyInfo. But I was pointed at rfc

Well, this really isn't a question for the TLS WG as DANE is external to TLS. With that said, ISTM that the primary purpose of DANE is to indicate which certificates are acceptable rather than to convey them, as TLS already knows how to convey them. -Ekr On Sun, Jun 26, 2022 at 5:05 AM Robert M

Kind of thought so. So where do I ask where CERT records are being used? thanks On 6/26/22 09:22, Eric Rescorla wrote: Well, this really isn't a question for the TLS WG as DANE is external to TLS. With that said, ISTM that the primary purpose of DANE is to indicate which certificates are ac

Thanks Eric! I will use them in draft-ietf-drip-registries for our X.509 certs and our 'custom' attestation certs (private OID will be needed). And then the powers-that-be can sort it out as we move forward. But at least this way I can put forth the discussion point and the implementors can

Viktor, thank you for your response. For those uses that are DANE/DANCE/TLS related, TLSA records WILL be used.  See draft-moskowitz-drip-secure-nrid-c2 Which I am working on an update to correct some errors and add MAVlink as a message format for NRID. and these TLSA records will be inst

Viktor, One thing I left off is that it is possible that draft-moskowitz-drip-nrid-c2 will be a major use case for DANCE as I have discussed on the DANCE list. The DRIP chairs want to wrap up current work before we tackle phase 2, but I have external players that want PoC for secure nrid NOW
