 The Apache httpd ACME module is called mod_md. It’s currently in the [development version of httpd](https://svn.apache.org/viewvc/httpd/httpd/trunk/modules/md/) and a plan is being formulated to backport it to an httpd 2.4.x stable release.

With the SSLPolicy directive, admins simply select a modern, intermediate, or old TLS configuration, and sensible choices will be made for them.
