I have used this article https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-16-04 to get my Ubuntu 16.04 server set up for SSL. I am going to use a security company that asks me to remove any existing SSL certificates and set-up. I was wondering the steps I need to take to reverse the above tutorial.
