It's <i>incredibly</i> difficult to keep people from using insecure technology.<p>After the whatsapp facebook aquisition many of my friends looked for something different. So they choose Threema and Telegram. Which are both <i>horrible</i>.<p>Please guys. Use TextSecure [0].<p>[0] <a href="https://en.wikipedia.org/wiki/TextSecure" rel="nofollow">https://en.wikipedia.org/wiki/TextSecure</a>
Just FYI. While Bitmessage is not a fast option (anti-spam proof-of-work per message may take a couple of minutes), it is a remarkable example of a very secure messaging tool in every aspect. Its design even gives you better privacy than Tor.<p>More info: <a href="https://bitmessage.org" rel="nofollow">https://bitmessage.org</a><p>The idea behind Bitmessage is that messages are fully encrypted (including recipient's address) with per-message random DH key derived from recipient's key. Then message is transmitted to everyone in a p2p network. Every node tries to decrypt the message with its key and if it succeeds - that's the message for them. If not, it passes the message to other nodes. Propagation time is quick, but to prevent DoS, each message goes with an expensive one-time proof-of-work proportional to the message size. Another measure is artificial separation of messages and nodes in "streams" so that message is only propagated within a smaller part of the network. As network grows this will not hurt privacy, but will keep amount of data flowing around in check. Bitmessage in principle is like email (that is checked every few minutes, not seconds) rather than real-time chat. But the idea could be brought to real-time chats too if we solve DoS and bandwidth issues in a different way.
Please guys, Use AlternativeChatAppNoneofThePeopleIKnowAreOn.<p>The real problem with all of these oh-so-secure-much-better-alternative-chat-apps is that nobody uses them. What's a communication network when there are no communicators? Just a network.<p>Unless X or Y gets better traction than WhatsApp, you will just be "that guy" who refuses to use WhatsApp and is instead on some novelty app nobody else uses. Though tinfoil insults are passé, they will bring them back just for you.
