Let's encrypt acme client

[arasscha1]

Hello,
I would like to understand how to use a DNS challenge if my service provider (Planethoster) is not recognized in the list of DNS challenges. Previously, I used a bash script to perform certbot, but I would like to integrate and use the firewall for this (with the aim of using Caddy later). Can you advise me?

If you want to use caddy you would need to build a caddy-dns package that supports your DNS Provider.

Here are examples:
https://github.com/caddy-dns
These depend libdns:
https://github.com/libdns

So a new provider needs two packages to be coded and built.
