-In OpenSSL before version 1.1.0, OBJ_cleanup() cleaned up the internal
-object table and was called before an application exits if any new objects were
-added using OBJ_create(). This function is deprecated in OpenSSL 1.1.0 and now
-does nothing if called. No explicit de-initialisation is now required. See
-L<OPENSSL_init_crypto(3)> for further information.
