Generating SSL certificates when Letsencrypt (what is Letsencrypt, who is behind it, and how the heck can you get started) is available for your system works in a breeze, but what if you need your certificates for a machine that won’t take Letsencrypt (for whatever reason)?

The result is much screaming&steaming from administrators who are in the middle of a job.
