This package implements the libdns interfaces for do.de, allowing you to manage DNS records.
The do.de API only supports creating and removing TXT records for domains starting with _acme-challenge.. This means that this package can only be used when issuing a TLS certificate using the DNS-01 Challenge.
To authenticate with the do.de API, you need an API token. You can retrieve by logging into your do.de account and navigating to Domains > Einstellungen > Let's Encrypt API-Token.
