Easy HTTPS for your private networks (www.getlocalcert.net)

This webpage provides instructions for using the acme-dns DNS challenge method with various ACME clients to obtain HTTPS certificates for private networks. Caddy, Traefik, cert-manager, acme.sh, LEGO and Certify The Web are listed as ACME clients that support acme-dns. For each client, configuration examples are provided that show how to set API credentials and other settings to use the acme-dns service at https://api.getlocalcert.net/api/v1/acme-dns-compat to obtain certificates. Interesting that so many ACME clients support the acme-dns service, providing an easy way to obtain HTTPS certificates for private networks.

seiferteric: Proposes an idea for automatically creating trusted certificates for new devices on a private network.

hartmel: Mentions SCEP which allows automatic certificate enrollment for network devices.

mananaysiempre: Thinks using EJBCA for this, as hartmel suggested, adds unnecessary complexity.

8organicbits: Describes a solution using getlocalcert which issues certificates for anonymous domain names.

austin-cheney: Has a solution using TypeScript that checks for existing certificates and creates them if needed, installing them in the OS and browser.

bruce511: Says automating the process is possible.

lolinder: Mentions Caddy will automatically create and manage certificates for local domains.

frfl: Uses Lego to get a Let's Encrypt certificate for a local network website using the DNS challenge.

donselaar: Recommends DANE which works well for private networks without a public CA, but lacks browser support.

Personally I use dnsrobocert with my own domains. I've got a few subdomains that point to a Wireguard subnet IP for private network apps (so it resolves to nothing if you're not on VPN). Having a real valid SSL cert is really nice vs self signing, and it keeps my browser with HTTPS-Everywhere happy.
