+Subject: [PATCH] ipsec-tools: add openssl 1.1 support
+To: equeiroz@troianet.com.br
+
+This patch updates the calls to openssl 1.1 API, and adds a
+compatibility layer so it compiles with (at least) openssl 1.0.2, I
+haven't tested it with lower versions, but all that's needed is to edit
+the openssl_compat.* files and add the missing functions there--they're
+usually trivial.
