What? No it’s not an unsolved crypto research problem. Signal supports group chats just fine, it’s just that’s it’s hidden away behind a couple extra clicks and you have to name them that inordinately annoys me compared to imessage where you just type the recipients out all in one place. It makes it feel like you’re Setting Up A Group instead of just bullshitting with friends.
- josh2600 7y agoYou misunderstand this problem. Doing group chat where you do a massive rekeying of all participants every time someone joins doesn’t scale, but it is secure. Signal doesn’t practically support large groups like Telegram does (although telegram is unencrypted as a result). I can assure you that large secure groups with strong cryptographic guarantees and evolving membership lists is unsolved.
- 6gvONxR4sf7o 7y agoNah, you misunderstand the complaint. The UX is annoying if you just want to message your friends Alice and Bob. On other platforms it's trivial. On those, you type alice into the new message bar, click her contact, type bob into the address bar, click his contact, then write your message and hit send. On signal, you have to create a new group first. I'm not talking about wanting to make the kinds of groups with dynamic membership like you're talking about.
