I’ve set up a server running Debian Jessie, which currently uses a self-signed certificate. Although this works for my own personal use I’ve hit a point where I want my server to be used by other people. In my application I want to install a Wordpress blog and have friends log in and add content to it, without having plain text passwords sent over the Internet and without them having to manually add a certificate to their certificates list for https to work.
I followed the self-signed certificates page on the Debian wiki: https://wiki.debian.org/Self-Signed_Certificate when I initially created my self-signed certificate. What I want to know is: will the self signed certificate be ignored? Should I follow the certbot installation instructions in my system’s current state? Should I undo the steps I followed to create my self-signed certificate?
