From 90446ff0273775ee20762bb892fd3e901c8eb8ac Mon Sep 17 00:00:00 2001 From: Michal Suchanek Date: Mon, 17 Jul 2023 21:23:51 +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.
