I have been using one machine to get letsencrypt certificates for several domains, and then distributing these files to all the machines that need them for web/smtp/etc ...
Recently due to an issue with a hosting provider the machine I was creating the certificates on was lost. Now all I have remaining of the accounts I need are the previous certificates, the keys, the previous CSR's, and the .conf files.
What I need is a way to generate new certificates - either by using these files, or by destroying the previous accounts and creating new ones. Is this at all possible?
My domain is: city8ball.org.au
The operating system my web server runs on is (include version): Debian Unstable
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No
I would just repeat whatever you did in the past.
There should be no conflict using a new system and having it use a brand-new account.
Keep in mind: That repeating the exact same solution is NOT a requirement.
You could come to a completely new solution to that same original problem.
There are many ways to obtain and distribute certs.
I say "repeat it" simply because you may be familiar with that solution.
