Apache SSL Reverse Proxy - Self Signed Sample

Sorry if this isn’t the best place to ask but I’ve setup reverse proxy with Apache to add authentication to Kibana. That was all relatively easy and my httpd.conf file is as such:

ProxyPass /
ProxyPassreverse /
<Location "/">
 AuthUserFile /opt/elk/users
 AuthName "This is a protected area"
 AuthGroupFile /dev/null
 AuthType Basic
 Require valid-user

What I'm trying to do now is make this SSL encrypted using a self-signed cert. eventually I'll try to move to a certificate that is built on our internal Microsoft CA server but for now just a simple self-signed would be good. Apache was compiled with mod_ssl.so so I think I’m just to the point of the actual config for ssl reverse proxy...

Does anyone have any simple setups or recommendations on where to go to get this information?
