Also, nice surprise mentioning it only there and not in the draft spec itself (complete with appropriate RFC-Editor notes). > I cannot seem to find an official registration with IANA though which > might cause implementation issues in the future if this extension type > is re-purposed. There is no registration for it. However, only draft implmentations send it (final ones won't), which should limit the damage, as draft implementations are meant for testing only, and not for general- purpose use. > Question: can we rely on this extension being used only for specifying > the TLS draft version?

Well, I don't suppose it will be re-used quickly... -Ilari _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
