TLS 1.2 has been obsolete for over three years. Oxford dictionary defines obsolete as "no longer produced or used; out of date." NIST requires support of TLS 1.3 everywhere no later than Jan 2024, which at least in theory means no negotiation of TLS 1.2.
I think IETF, TLS WG, and TLS libraries should spend their time on TLS 1.3 rather than giving the false idea it is ok to stay on TLS 1.2. John From: TLS <tls-boun...@ietf.org> on behalf of Hannes Tschofenig <hannes.tschofe...@arm.com> Date: Monday, 25 October 2021 at 19:12 To: IETF TLS <tls@ietf.org> Subject: [TLS] Flags Extension: why only for TLS 1.3? Hi all, why is the flags extension only defined for TLS 1.3? There is nothing in this extension that prevents us from using it also in TLS 1.2. Could we make it also available to TLS 1.2?
