| From f7a2e90e80fd8b4c43042f8099e821b4118234d1 Mon Sep 17 00:00:00 2001 |
| From: William Roberts <william.c.roberts@intel.com> |
| Date: Fri, 3 Sep 2021 11:24:40 -0500 |
| Subject: [PATCH 1/2] ssl: compile against OSSL 3.0 |
| |
| Compile against OpenSSL. This moves functions non-deprecated things if |
| possible and ignores deprecation warnings when not. Padding manipulation |
| routines seem to have been marked deprecated in OSSL 3.0, so we need to |
| figure out a porting strategy here. |
| |
| Fixes: #686 |
