Hi, I wanna know what is the most secure and best messaging app/platform… Need an app that is crossplatform and has a very good numbers of features and security. (And it has to be FLOSS) I thought about XMPP clients, Signal, Session, IRC clients… Propose and explain me your choice

    It’s basically just Signal if you want ease of use + good security. Not totally 100% since it is funded almost exclusively by the US govt, and I can’t be sure if the encryption is not backdoored, but it’s the best bet we got. IRC: not secure, XMPP / Matrix maybe ok but hard to use for most, Telegram wouldn’t really trust though in theory has e2e, Whatsapp and Google world stuff even less faith. Honestly none of it is super great, but Signal has the best balance imo. There’s also some crypto based messaging stuff that’s used on darknets but that’s the clunkiest

    I think the only fully guaranteed method is having a pre shared one time pad encryption key between two parties & then send the encrypted text however you want (ex post on a far corner of a mostly dead online forum or Reddit). That doesn’t have any fancy algos that may be bugged, or private/public key stuff

      I think we can be pretty damn sure that the encryption is not backdoored since the Signal Protocol is the gold standard in encryption nowadays and thousands if not more highly skilled cryptographers without tied to the US govt looked at it thoroughly. Also Snowden calls Signal the best messenger on the grounds on him using it daily and still being alive so that’s also a pretty good sign.

      Also, do you have a source about them being mainly funded by the US govt? In their blog they talked about mainly being funded by small donors and a few initial loans from people who care about privacy.

        I think than Signal messages are mostly not backdoored but maybe all the profile picture, the name and the description are surely leaked to US gov if they found most of the servers

          That’s not how it works. All metadata is also E2EE with the same protocol. Even if they control all servers it wouldn’t change much.

        The real litmus test right here.

          I don’t think so, do you think it is better to arrest 1 person and make flew away all the others users than let this guy live in peace and spy on millions others?

            I mean if they’d use the backdoor no one would know. It’s not like they would declare ah ye we used our secret Signal backdoor.
