  2. One of the projects I alluded to in that post makes a technological solution to what you want easy to build, but the harder problem to solve is societal (i.e., getting it adopted). https://github.com/fedi-e2ee/public-key-directory-specifica…

  3. > The so-called web of trust is meaningless security theatre. Ignoring your comment’s lack of constructive criticism, I’m going to post this meaningful implementation that an excellent cryptographer, Soatok Dreamseeker, is working on: [1].…

  4. Why is a keyring important to you? Would "fetch a short-lived age public key" serve your use case? If so, then an age plugin that build atop the AuxData feature in my Fediverse Public Key Directory spec might be a solution.…

  9. > If you have some hash function H = sha256 let us say, you could calculate h = H('{"name" : "bob", "pubkey" : "1A1zP1e"}')[:N] and then set record[57] = h (I'll use a 24-bit h = 71b686 for my examples, OP suggests a 48-bit). You're…

  11. > Is the intention that E2EE have a separate, parallel account recovery mechanism with more difficult requirements? I'm not sure the wording here is helpful. Let's start with a simple diagram: https://github.com/fedi-e2ee/public-key-directo…

  12. Not if the admin tampers with your bio! Not if the instance software itself gets hacked, either. See https://github.com/fedi-e2ee/public-key-directory-specificat... for a detailed threat model.

  13. I'm building an open source Federated Public Key Directory, so that I can then build end-to-end encryption for the Fediverse. https://github.com/fedi-e2ee/public-key-directory-specificat... Think: Encrypted DMs for Mastodon. I wrote…
