:OpenSSL is currently considering the deprecation of the TLS 1.0/1.1 :protocols. Currently TLS1.1 and TLS 1.0 are disabled at run time, and :requires enablement by reducing the ssl security level value. : :The current proposal under consideration is to explicitly disable TLS :1.0/1.1 at build time, in our 4.0 release (tentatively scheduled to release :in the next 12-18 months), with an eye to completely remove the impacted :code in a future major release. The default configuration could be :overridden to re-enable TLS 1.0/1.1 at build time. : :Questions to the community are: : :1) Are distributions/users comfortable with this approach in the time frame :proposed?
Not really. Entities who control the OpenSSL they run on their systems, OSes, etc. don't necessarily control all the broken things that said systems/OSes need to interact with. :2) Would builders of OpenSSL consider using the default configuration (with :TLS1.0/1.1 disabled in 4.0), or would they ship with these protocols :re-enabled in their builds? Either it'd be re-enabled in the build, or there'll be a fork that supports TLS 1.0/1.1 in relative perpetuity. It was only recently that some mainstream Linuxes stopped shipping a compat openssl 0.9.8 and all the stale protocol baggage that goes along with that, for support of some "business critical" commercial apps. :3) If the deprecated protocols are re-enabled, what would constitute a :reasonable warning mechanism to inform users that these protocols are going :away at some point in the future to pressure users to update to a newer, :more secure protocol? I'd be inclined to position such a move and associated warning message in terms of PQC, which AFAIK doesn't and won't support TLS 1.0/1.1. As PQC gets "refined", it wouldn't surprise me to see the quantum computing boogeyman drive out TLS 1.0/1.1 in critical applications. Let PQC be the spike that kills TLS 1.0/1.1 dead. I've been leery to post this for fear of going too far down some "quantum" rat's nest. So please, be gentle. Take FWIW... -Mike -- Michael J.
