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

    I wanna get something that could be tweaked like changing the encryption… Something really customizable, maybe running my XMPP server

      So you want self hosted? And what you mean by changing the encryption? Changing the encryption protocol and encryption algorithm are two different thing. OMEMO is kind of de facto for XMPP. Last I checked it seems doesn’t let you choose the cipher suite like TLS 1.2 does. You can spin another if you have the capability to do so but not recommend.

      And whatelse you want to tweek?

        That would be cool to have a messaging app that let me change almost what I want like the encryption protocol, changing the encryption keys… And so on, don’t know if it’s possible

          Key? Oh, welcome to the land of GPG/OTP where platform and protocol doesn’t matter. Good luck finding a friend willing to deal with this just to talk to you though. And loose some important security features like forward secrecy and double ratchet.
