Hi @alextech
If you review the Really Simple SSL plugins GitHub Page
No setup required! You only need an SSL certificate, and this plugin will do the rest.
== Description ==
Really Simple SSL automatically detects your settings and configures your website to run over https.
To keep it lightweight, the options are kept to a minimum. The entire site will move to SSL.
= Three simple steps for setup: =
*** Get an SSL certificate (can't do that for you, sorry).**
- Activate this plugin
- Enable SSL with one click
In short Really Simple SSL is a plugin for updating WordPress from HTTP to HTTPS (for word press only)
You still need to obtain and install a certificate
There are several good guides on how to do this on your best friend Google
