From f23f45413fd02c180182cd341b800e2b9fa169f4 Mon Sep 17 00:00:00 2001 From: Honza Horak Date: Tue, 8 Feb 2022 16:39:10 +0100 Subject: MDEV-27778 md5 in FIPS crashes with OpenSSL 3.0.0 OpenSSL 3.0.0+ does not support EVP_MD_CTX_FLAG_NON_FIPS_ALLOW any longer. In OpenSSL 1.1.1 the non FIPS allowed flag is context specific, while in 3.0.0+ it is a different EVP_MD provider.
