Group messaging

I would say session keys are very important in group messaging since it's the currently known best method to feasibly create large end-to-end encrypted group chats.

The method is to generate a session key whenever the group changes, or the session expires, then send all the participants the new session key using conventional end-to-end methods (like using public key one-to-one snding), so the group messages don't have to carry keys for every participants.^[1] But I am no crypto god to insert this into the article right away, some more eyes are appreciated. Feel free to include it, though. --grin ✎ 11:20, 21 August 2019 (UTC)[reply]
