Easy HTTPS for your private networks
Easy HTTPS for your private networks
getlocalcert helps you manage HTTPS on private, local, and internal networks with free subdomains
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.

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.
