Hi! My printer has the option to import .cert files to encrypt connections from computers. I wonder if there is any way to generate the Letsencrypt .cert file using an internal domain name or IP number. Any advice is welcome!
The DNS challenge is probably the best / easiest. all the Bash and Go alternate clients support this ( and maybe a few others )
“Internal domain name” suggests (to me) a non-public host name…? Perhaps @itmonitor could clarify if it’s an actual public available host name.
For the DNS challenge it doesn’t need an external A record or anything ( as long as it’s within a domain you own, and you can add a TXT record to the DNS )
It’s quite hard for Boulder to find the TXT record for
hp1600.home.local That’s what I meant.
Unless @itmonitor gives us more information, it’s not really possible to give a good and solid advice.
“internal domain name” could equally be “printer2.myrealdomain.com” I understand where you are coming from though.
Thank you for the replies. Yes, I mean a non-public host name. Yes, that could be like printer. mydomain.com or even a local domain like the ones used to generate a self-signing certificate.
If you mean a local domain like “printer.made_up_name.local” then it’s not possible to obtain a certificate for it.
Serverco, many thanks. It is clear for me now. This thread is solved.
