Description

Maybe adding site configs could be made a bit easier by simply making it so that:

  • the config needs to be exposed at https://$somesite/.well-known/keybase-config.json
  • the hash of the config can be stored in a TXT entry at the same domain using keybase-config-hash=<sha512>
  • that hash can be verified to really belong to that domain using DNSSEC

This way if a site supports DNSSEC and happens to run mastadon (or any other kb-supporting software) things will just work ™️ for them

Possible problem is time (changes being made to config and messing with previous proofs), but this could be solved by simply never changing the way proofs are getting fetched (that way the config only changes the way they are created)

Research direction

The issue contains no file, test, or entry point to begin from. First determine where site proof fetching and creation are implemented, then establish how .well-known configuration, DNS TXT records, and DNSSEC verification should interact. Done should include an agreed design and tests for fetching, hashing, and verifying the configuration.
