Presentation:
We had a long open discussion about many topics. Of particular interest was certificate authorities.
When setting up a lab of computers, perhaps in a virtual environment, it is good to have valid certificates. Of course there is the option to purchase a wildcard certificate from any of the certificate providers. If there is no budget available, it is good to investigate Let’s Encrypt and the certbot program to manage certificates. Let’s Encrypt may not work if you do not have a webserver or DNS server accessible from the Internet.
Fortunately there is a third option…create your own certificate authority. We will investigate this option at a future meeting.
