i’m trying to generate a certificate for a domain of mine and multiple subdomains of it. The problem i’m suffering is that some of these domains are not available through HTTP service. For example i would liek to get a certificate for:
hostname.example.com, hostname.example.bar, hostname.example.bar, mail.example.com, mail.example.bar, mail.example.foo, smtp.example.com, smtp.example.bar, smtp.example.fooo and so on: Those subdomains are not available through HTTP.
Does anyone know how could i proceed in order to generate these certificate for those domains/subdomains avoiding to use --manual option? Maybe i could create some kind of txt on DNS zone?
I’ve also seen these - Boulder github.com/letsencrypt/boulder - repository but still don’t know if it could help me.
