<p>
This page covers backwards compatibility between mod_ssl and other
SSL solutions.  mod_ssl is not the only SSL solution for Apache; four
additional products are (or were) also available: Ben Laurie's freely
available <a href="http://www.apache-ssl.org/">Apache-SSL</a> (from
where mod_ssl were originally derived in 1998), Red Hat's commercial
Secure Web Server (which was based on mod_ssl), Covalent's commercial
Raven SSL Module (also based on
mod_ssl) and finally C2Net's (now Red Hat's) commercial product <a href="http://www.redhat.com/explore/stronghold/">Stronghold</a> (based
on a different evolution branch named Sioux up to Stronghold 2.x and
based on mod_ssl since Stronghold 3.x).</p>

<p>
mod_ssl mostly provides a superset of the functionality of all the other
solutions, so it's simple to migrate from one of the older modules to
mod_ssl. The configuration directives and environment variable names
used by the older SSL solutions vary from those used in mod_ssl;
mapping tables are included here to give the equivalents used by mod_ssl.</p>

because of special functionality in these interfaces which mod_ssl
doesn't provide.</p>
