Usage also for (D)TLS 1.2

[boaks]

Though the title implies for me, that only the usage with (D)TLS 1.3 is considered, I'm not sure about the intention according (DT)TLS 1.2?

DTLS-RRC is considering to use this, with that, the answer to the support for DTLS 1.2 may get important.

[yoavnir]

All extensions apply to DTLS. For some reason, the registry allows you to specify that an extension is DTLS only, but not that it is inappropriate for DTLS:
https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#tls-extensiontype-values-1

It's more about 1.2 and 1.3.
Not about TLS and DTLS.

[yoavnir]

I see.

Support for TLS 1.2 or just DTLS 1.2 is a bigger change than I can just add here. I encourage you and Thomas to raise this issue on the TLS mailing list. Maybe also at the TLS meeting.

Thanks @yoavnir -- Hannes brought the topic to the list but there was no followup.

Maybe also at the TLS meeting.

I don't see tlsflags on the (WIP) agenda for IETF 112. Are you planning to present it there?

@yoavnir if you'd like some time to discuss tls-flags and the question of 1.2 support, please let me know!

Now I am. It's on the agenda

Per discussion in IETF 112, there did not seem to be consensus to back port this for 1.2. Closing.
