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.
Sounds like a bad browser.
Good browsers don’t let random unauthenticated content to do whatever it wants on neither the local machine or the network.
HTTPS is also the only way to use client-side certificates for strong two-way authentication and zero-trust setups.
So, lynx?
lynx, no-script… it’s all fine until some web needs JavaScript yes or yes, which nowadays seem to be most of them, then it’s a game of whom to trust.
Private networks are usually an oxymoron, they’re only as private as far as the WiFi router or whoever clicks the wrong malicious link go. Zero-trust mitigates that, instead of blindly relying on perimeter defenses and trusting anyone who manages to bypass them.
This is your brain on webshit.
You may want to rephrase that?
Every browser implements these limitations, as they’re part of the web platform. Some examples are service workers, web crypto, HTTP/2, webcam, microphone, geolocation, and more. There’s a list here: https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts/features_restricted_to_secure_contexts
Sounds like a bad browser.
Every browser does this. It’s intentional to push people towards using encrypted connections, especially for PII like geolocation.
Sounds dystopian. I still won’t feel bad for normies.
So, Chrome, FireFox, Edge, Safari, Opera, every other browser I’ve ever heard of, are all “bad browsers” in your opinion?
Plenty of non-browser related reasons to want HTTPS in your own network.
If you need it/should use it depends on your system architecture and level of paranoia.
For instance we’re running all our stuff in a virtualized Linux environment on-premise on our own hardware. There’s a firewall zone from the outside and in, several zones for different applications.
We terminate SSL at the edge and use port 80 for anything internal that’s HTTP.
While that opens us up to internal eavesdropping my argument is that anyone that deep in our system will have compromised everything anyways.
On the other hand it allows our firewall to do application filtering, including killing bad (as in faith) incoming requests.
The only caveat to that is that some of our external pen-testers think they’ve found a DOS scenario in our application when all that happens is that the firewall drops the connection.
If I was routing traffic over a shared network or multiple sites I’d definitely employ HTTPS.
All this said, I’m sure someone smarter than me have written better opinions on the topic.
For example, my browser won’t auto-fill a credit card without a valid HTTPS connection. And as someone who does QA on payment pages, I find myself typing out the standard VISA test card number
4200 0000 0000 0000[tab]12/34[tab]123about a thousand times a day. Every ten minutes or so I type the wrong number of zeros and have to go back and try again. With a working HTTPS connection, the browser will fill it out for me. So much better.
