Newbie looking for some guidance.

Greetings...

We are attempting to add SSL to a server currently in production.  Some details:

AIX 5.2
Apache 2.0.39 (I did not install it, but I'm guessing it wasn't installed with mod_ssl)
just installed openssl 0.9.7d-1 (rpm prepared for AIX)

I'm familiar with setting up virtual hosts and have found some examples relating to virtual hosts and ssl...  I'm just a bit confused about a couple of things:

1.  Is there a way to install mod_ssl once apache has been installed?
2.  What is the role of the SSL.conf file?  

Anything that might point to a good reference would be appreciated.  I'm not seeing anything specific to this in the FAQs.

Thanks,

Tony Andrews
