This quick tip involves a web site setup which includes an SSL (Secure Socket Layer) certificate, to take your site from http to https. However, directions for setting up the SSL on your site are not covered, only how to implement the http to https redirect.
Plugins Used to Complete

Using the Really Simple SSL plugin here, I received this notice, but it was due to not having the "Keep HTML comments?" checked while optimizing HTML using the Autoptimize plugin.

A web site with https, which allows for a secure web site. You will also want to make sure that the site and wordpress addresses under Settings > General have been changed to https
