Hey everyone.
I make Peersuite, an opensource free communication platform.
It's private by default, there's no sign-in or email collection.
It's peer-to-peer, there's no server, after discovery you are connected directly to your friends my AES-GCN encrypted WebRTC channels. It forms a mesh and identifies superpeers. Because there is no server, in order to save your data between sessions, you can download your workspace into a password encrypted file. Happy to answer any questions.
FEATURES: chat with images, PMs, channels, and file send group audio/video calling screensharing kanban board whiteboard for diagrams/flowchartswith PNG export collaborative document editing with formatted PDF export
The best way for self hosting is docker, its on dockerhub as openconstruct/peersuite. You can also download desktop versions from the github or use on the web at https://peersuite.space/
There is literally no way to do performant e2ee at large scale. e2ee works by encrypting every message for every recipient, on the users device.
At 1000 users, that's basically a public room.
I haven't had a chance to test the limits of Peersuite, but since it's a mesh network, I don't think it would run well with even 100 people.
@moonpiedumplings @jagged_circle I read your initial question as 1,000 active chat *rooms* (with some large number of users for each), which.. seems excessive. That's what I was referring to.
1,000 individual private 1-on-1 chats (or group chats with 2-3 users), if that's what you meant (and especially over a long period of time, with lots of inactive chats), seems like a more common scenario*. If that was your question, I apologize.
Lol I misread it too.
@moonpiedumplings @jagged_circle
* I can't speak on behalf of the author, but I could imagine handling it by simply not decrypting _everything_ on startup, and only decrypting an older chat if you click on it or attempt to run a search on everything. Although for a search, I would expect some kind of hashed (and of course encrypted) database that allows a quick search of all prior messages.
Everything is decrypted on exiting transit. I use WebRTC for all the data.
Honestly I would just copy what matrix did in 2.0
I didn't say 1,000 users.
