Important progress has been made regarding bringing MLS end-to-end encryption to the ActivityPub protocol, with developers already building implementations and providing feedback to a future version of the protocol spec.

Fake journalists not even bothering to google that XMPP exists #10496839485.

This is about implementing E2EE directly into ActivityPub, so that has nothing to do with this.

[–] iltg@sh.itjust.works 20 points 8 hours ago* (last edited 8 hours ago) (1 children)

this is misleading and sensationalistic. if emissary implements e2ee, it's not "e2ee for the fediverse", it's " e2ee for emissary users". did mastodon talk about e2ee? did lemmy?

also the MLS draft (supposedly "better than signal ") proposes for trusted key exchange either " trust the server" (lmao), use a centralized key authority (wow) or have users manually verify their keys out of band (so basically use matrix to assure your chat is encrypted). source: https://swicg.github.io/activitypub-e2ee/architectural-variations.html#validating-end-to-end-encryption

fedi devs need to stop clickbaiting, and fedi users should learn a bit more about their protocol to avoid getting misled this way

I felt like a 90 year old grandma reading this.

[–] gajahmada@awful.systems 3 points 4 hours ago* (last edited 4 hours ago)

You and me both.

But after pondering the orbs for a minute I think they're saying, that it's just Emissary trying to get E2EE working and not Fediverse as a whole.

And they follow with some objection with the proposed draft. I can only comment on the 3rd one, it basically mean you need other channel of communication to manually compare fingerprint (i.e via Matrix/Signal) to make sure your activities on Emissary is actually encrypted, maybe lol.

Fediverse and Linux have to be the most unholy tech union in existence.

I have a bit of an issue with the title, considering federated end to end encrypted messaging has existed since, at the latest, 1991.

[–] realitista@lemmus.org 4 points 9 hours ago (1 children)

What's the messaging protocol?

[–] sefra1@lemmy.zip 10 points 9 hours ago

Pgp is protocol agnostic, you can use it over email, xmpp, irc... Over pretty much anything that supports plugins.

It's usually used for email tho.

[–] Steve@communick.news 69 points 16 hours ago (4 children)

I thought we already had Matrix

[–] MentalEdge@sopuli.xyz 68 points 15 hours ago (25 children)

We do.

This is for activitypub DMs.

And XMPP before it, even for e2ee messaging.
At least this is a slightly different use case.

[–] HailHydra@infosec.pub 7 points 13 hours ago

Matrix is a poor choice from a cryptographic perspective. With some serious issues historically (some of which are still unfixed to this day), and an extremely poor response to disclosures.

Matrix is decentralized but its not federating in a way like activity pub is doing

[–] Steve@communick.news 23 points 15 hours ago* (last edited 15 hours ago) (4 children)

ActivityPub isn't the only way to federate.
It's federating the same way email does. Anyone can spin up their own server. And if they want anyone can spin up their own software. That's what federation is. Different servers agreeing on how to communicate with each other.

[–] Lost_My_Mind@lemmy.world 7 points 14 hours ago

What??? I thought being part of Federation meant being part of the WORLD WRESTLING FEDERATION!

OOOOH YEAH, SEE I'M ALWAYS THINKIN THINKIN THINKIN, YEAH. AND WHEN IT'S ALL SAID AND DONE, WE DO THING IN THE RING! DIG IT! THE TOWER OF POWER TOO SWEET TO BE SOUR, FUNKY LIKE A MONKEY! OOOOOOH YEEEAAAHHHH!!!!

Pomp and circumstance plays over the house speakers

ELIZABETH!!!

How so? It's certainly very similar.

The matrix protocol enables federation between different instances running different homeservers between users using different clients.

Especially with the Movim client :)

[–] Lost_My_Mind@lemmy.world 45 points 16 hours ago (2 children)

Well now this sounds interesting. And I assume it's open source?

[–] A_norny_mousse@piefed.zip 4 points 9 hours ago* (last edited 9 hours ago)

🤯 That gave me pause. What made you ask (would non-FOSS even be an option for anything ActivityPub)?

[–] Successful_Try543@feddit.org 7 points 12 hours ago

It seems so, as the project (Emissary) is using the GNU Affero GPL.

[–] 9tr6gyp3@lemmy.world 15 points 16 hours ago

MLS will eventually be included in all messengers.

It was initially introduced by Wire as an RFC, but they fumbled the federation by making it an enterprise only feature. Because of that, other messengers will do the federating for them. iMessage, Google Messenger, Matrix, and Germ DM (Bluesky) do or partly have it implemented.

We should always have more alternatives to chose from - good to see so many players.

[–] helvetpuli@sopuli.xyz 6 points 14 hours ago

@benpate@mastodon.technology that's amazingly quick work after just under four weeks. I'm looking forward to the result.
