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? 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? 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? Input on these questions is requested and appreciated
