You can't have one standard and do XMPP, IRC, MOV and OMEMO at the same time :) There should be many standards and let the best one win.

I can send OMEMO messages between XMPP and IRC. But that's besides the point. My comment about having one standard was about not having one for DM's and another for group chats, when everyone is using only one (because group chats serves for DM's).

I am not sure if it's possible (or desirable). Usually there are specific features (or simplifications) on each of them to warn a separate protocol. For instance, if you are doing a private zap, you want the amount to be public and the rest private, which creates metadata leaks on purpose. Sometimes, "leaks" are desirable. In other times they must be forbidden. But who knows, maybe there is a way to merge them all.

@Vitor Pamplona In other words, why reinventing the wheel when OMEMO does everything and has already been implemented on the web?

because we need to port things to fit into Nostr. There is no way to just reuse things out there.

OMEMO is pretty cool. How does OMEMO accomplish syncing between user devices? @JeffG @jb55 According to Straub, OMEMO uses the Double Ratchet Algorithm "to provide multi-end to multi-end encryption, allowing messages to be synchronized securely across multiple clients, even if some of them are offline" Bold claims. Sounds like exactly what we need… 🤔

Yes, it is exactly what we need, and it's already been implemented in web clients.

The name "OMEMO" is a recursive acronym for "OMEMO Multi-End Message and Object Encryption". 🌀 Multi-end is literally in the name… interesting. Maybe something you can learn here for your spec’ @JeffG

I’ll definitely have a look into it. It’s probably all based on the same principles.

In the two minutes look I just took at Omemo, it looks like it’s using the same principles that signal and my NIP are using. I’d be willing to bet the device syncing is the same. In any case. I’ll definitely take what i can from it. Fwiw; group messaging is doable with this basic system as well.

Both Signal and OMEMO use Double Ratchet, so probably! Imagine if you pull off crafting a hybrid spec combining the best of both on Nostr… Godspeed! 🫡

💯🤙

we will because it's so simple

Signal Encryption vs. XMPP Omemo

I am wondering the main differences between the two types of encryption. I use XMPP with some family and friends with Omemo enabled, but wasn

To sum it up: 1. OMEMO is essentially Signal's encryption protocol (and it is web, thanks to movim folks). 2. The rest of the Signal protocol is snake oil. 3. Anonymization should be worked on a different layer. For point three I have a solution in mind that would like to discuss with anyone interested in funding the project.
