I’d like to use an existing private key with certbot for request and renewal of letsencrypt certificates. In the certbot documentation/FAQ I found that it was possible (yay! \o/) but not how to do that.
If possible, I’d like to use the key and not a csr because I want certbot to do as much work as possible
On my first try, I used certbot with
--key-path pointing to the private key in question but that didn’t work.
