yaxim client OMEMO ("better" than OTR)

[solarnoid]

#82 (Support OTR encryption)

Will there be client support for OMEMO for interop with other supporting clients like Conversations

[ge0rg]

Yes I have plans for OMEMO. Somebody just needs to implement it.

I'm working on a Smack module as part of my bachelors thesis. This might solve the issue when its done :)

Maybe, after all, OTR is better? For OMEMO, the server must support it.
For example, I encrypt OTR messages with users Mail.Ru Agent via XMPP transport, and with OMEMO, it seems, so impossible.

[vanitasvitae]

@Urgant OTR does not suppport offline messages, as well as mutliple recipient devices at once.

Its true, that the server has support PubSub, but PubSub support becomes more and more a criteria for a "good" server.

Btw:

Smack does now have OMEMO support :)

I do not need offline messages, but with users of other protocols I sometimes communicate through XMPP transports and I would like this communication to be encrypted. Now we use OTR. How can OMEMO do this?

[vanitasvitae]

OMEMO cannot do this, but what you describe is definitelly what I'd consider an exotic usecase. Also OMEMO and OTR are not mutually exclusive. That means you can switch between them :)

Ah, if only that. But I would say that exotic is more like XMPP. The same Mail.Ru Agent is used every month by 18.8 million people in the world. And with them you need to be able to encrypt the correspondence through XMPP transport. And in Yaxim there is no OTR.

[ge0rg]

@Urgant while I can see your reasoning, OTR is a real mess when any person involved uses more than one client. This issue is strictly about OMEMO. Please read up in #82 why yaxim doesn't have and won't have support for OTR.

[mvhulten]

OMEMO would be a great addition. If it were included, yaxim would be for me a good, light alternative for Conversations.

[d668]

so no OMEMO at the moment?

[ge0rg]

There is work on moving from my ancient rotting Smack fork to Smack4.3 right now. If there is an easy-to-plug-in OMEMO implementation in that, it might come sooner than you think. But right now, there is zero code for OMEMO support in yaxim, and I have zero time to pursuit that.
