From c081558cc4d94f4cd1a4498ba43339d1bf05f5d7 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Mon, 19 Mar 2018 20:33:50 +0100 Subject: [PATCH] s_client, s_server: do generic SSL configuration first, specialization after We did the SSL_CONF_cmd() pass last of all things that could affect the SSL ctx. However, the results of this, for example: -max_protocol TLSv1.3 -tls1_2 ... would mean that the protocol min got set to TLSv1.2 and the protocol max to TLSv1.3, when they should clearly both be TLSv1.2. However, if we see the SSL_CONF_cmd() switches as generic and those internal to s_client and s_server as specialisations, we get something that makes a little more sense.
