    > any idea why https://koishi.pain.agency/matrix-proxy/0bc9b146-bf41-4bd1-a26b-996d2d4df287/image.png wont embed in an xmpp client? if i curl it to a file it seems correct but gajim will just dissapear the download and dino blanks out the message 503 bad gateway for me ↺

    Do you know how the decrypted payload looks like in OMEMO? Is it an XML stanza? Plaintext? Something else?

    But beware there are older versions of the spec where just the message string was encrypted and not xml

  5. moparisthebest

    and by "older versions" you mean the one gajim and everything else supports right now, vs the link which maybe 1 client supports (:

  6. franco

    That's very useful insight, thanks ✎

  7. franco

    Those are very useful insights. Thank you both ✏

    in the most commonly supported o.3 version, only the <body> tag of the overall xml message stanzs is encrypted

  9. wgreenhouse

    which is why things like reactions currently pose a leak, if allowed by your client during an OMEMO session

    *stanza

    *0.3

    I will look at my logs to see

    For omemo it was in a <payload> which is inside <encrypted>. While reaction was an unencrypted <reaction> with a stanza.

    I'm trying to figure a way to keep E2EE through a bridge if the other end also implements Signal Protocol for E2EE (for ex., Matrix). Maybe if clients supported converting the payloads from/to XML/JSON, after decryption 🤔

  15. franco

    I've looked at mautrix-whatsapp (which bridges Matrix and WhatsApp), but they don't preserve the E2EE (the bridge is a MitM).

  16. stratself

    I really don't think any bridge could do E2EE unless protocols pre-agree with what to send

  17. stratself

    which is what IETF MIMI is supposed to solve

  18. singpolyma

    it would have been possible with oldmemo but yeah, not realistic in general unless both sides speak the same "inner format"

    Is anyone here attending the MIMI WG meetings? I'd like to
