XMPP + GSoC - 2026-01-16

Let me write out something for Convo. I've been meaning to do that anyway

As usual, when I start writing I really *write* 😅

Here's a project proposal for Convo emus: https://pad.disroot.org/p/r.b00aa9f51eb881955116a24dd1a87846

Regarding contributors: I have been speaking to a few people (including untrusem and kishy who are in this group!)

I think it's good for a newcomer project mainly because it touches on a lot of areas (XMPP, XEPs, UX design, writing a Converse.js plugin, writing frontend interfaces) but all at a very contained level (only one or two XEPs to focus on really with the rest already taken care of; button phone so less things to think about for design; existing plugins to use as a guide; lots of existing frontend screens to refer to when making a new one)

Or in a nutshell the "Stories" feature is rather like making a mini app but inside a larger app that's already taken care of many of the more complex details ✏

Today seems to be a day for missing 'by's! Thanks sch

Thank you very much badrihippo. Can you ask Vishnu to be present here?

But folks, I don't think that Cross-signing dvices is anything for GSoC students unless you have a pre-candidate with pre-experience.

emus: we have one potential candidate and we discussed this idea with them planning to apply for grants, but that plan did not work.

One more question: Are you actually allowed to participate due to NLnet funding?

But we have now added smaller tasks of this idea in the same pad, like verify devices by comparing emojis.

in the Cross-signing thing? I would >only< promote these simple ideas.

So we have 4 smaller tasks of cross signing for newbies.

Yes, same doc linked from wiki.

It is added at the top.

Okay, but only expose these ones, not the difficult ones. This is sensitive and you need to do this right I assume.

But this is not a trivial task? Sign and publish signatures on omemo keys: We should be able to track device trust path by using digital signatures. We can use a device's omemo key to sign another device's omemo key. Explore if the current key format supports storing signatures If not, create a specification to publish detached signatures in pubsub node. Create an XEP for creating signatures for omemo keys. Create and publish and identity key: Generate a key pair per account using the same method as a omemo device key. Intially we cosidered using OX keys, but OpenPGP would add more challenges to implementation, especially on iOS. So the key will be conceptually similar to OX keys, but use the omemo algorithms instead of openPGP. Publish the key similar to OX. Implement secure local storage with password Implement key export and import Implement backup of the key on the server with a password Implement restoring th key on a new device.

Badri can answer about NLnet. Grant was for Convo, not for Prav.

Yes, but Convo is applying for GSoC, too. That's the conflict.

Signing or key generation will only need using existing libraries. And publishing is just publishing to a pubsub node.

I don't think NLnet funding and gsoc are mutually exclusive. I mean - very obviously - it can't be the same work. But otherwise it's fine

And the mentor can't bill their mentoring to NLnet but I don't think anyone was planning on doing that

Apparently the Nlnet work is moving to a new UI framework, enabling omemo and some IM compliance work (https://nlnet.nl/project/Convo/) Stories doesn't seem to be part of that grant

Thanks for the clarification.

> Apparently the Nlnet work is moving to a new UI framework, enabling omemo and some IM compliance work (https://nlnet.nl/project/Convo/) > > Stories doesn't seem to be part of that grant I'm not sure if I fully understand your point? ↺

I meant according to the public documents we have Stories (the proposed gsoc task) is not part the work done with Nlnet money

Okay, thanks, yes. Just wanted to mention this potential circumstance so we don't get in trouble. praveen can you update the wiki and the pad to highlight only the simple tasks and their time consumption?

emus: OK I hope we can do the full project if the student who worked with us earlier proposes the full project.

praveen here you can update: https://wiki.xmpp.org/web/Google_Summer_of_Code_2026#Project_Ideas

Okay
