From 1bb23d7f19d888fbdd96ae0fe929b7086713ef33 Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Tue, 18 Jul 2023 14:01:52 +0200 Subject: [PATCH] configure: Detect openssl sm3 support Older openssl versions do not support sm3. The code has an option to disable the sm3 hash but the lack of openssl support is not detected automatically.
