Basically I am looking for a messaging platform like signal or? but with anonymous signup, perfect forward secrecy, capable of video chat, sending photos the usual uses in today’s life. But with a panic button. So that any party member could use said button to wipe all other members devices of any data instantly inside the messaging app. So if one member gets compromised, or lost their device, stolen device ect, any other member could wipe all chats, call log, and any other data strictly inside the messaging client instantly for everyone involved. Disolving the group like it never existed rendering the data unrecoverable. Amazons Wickr used to have most of these features but it is being discontinued December 2023 and who trusts amazon with their data. Does something like this exist? Sorry if I’m not explaining it well I’ll do my best to clarify and update this post. I am not trying to delete the whole device. Just the data inside the messaging app. If that does not exist. What about a separate app that could delete the entire messaging platform from the device when triggered. Assume all necessary requirements are met and this is for daily use. Between a group of trusted parties.
Updated wording to clarify the objective as replies where getting misunderstood.
you can also look into hosted services like EMS but I don’t know if you have to provide identifiable info.
it’s all encrypted on the client -> e2e. even if it was http and no SSL
you have to provide a domain, I’m not sure how easy it would be to run it without and only locally on a LAN. IT’s possible but the experience wont be good. you also can’t federate. It’s much easier to use a hosted server.
the same way like you’d do it with a publicly exposed host.
BUT I think I’d go with p2p matrix before going the LAN route.
Here’s a p2p matrix built https://drive.google.com/drive/mobile/folders/1uK_BcHGiAYHkN6OAA7P73obAquwShRg5
