Usable Privacy Focused Communication

The holy grail for mass adoption of encrypted chat and email, but I’m not going to lecture about why this is important. Instead, I want to list some of the tools that are cropping up, list some pros and cons, and hopefully keep it up to date, and help a few people keep their personal lives, personal.

EFF recently put up their Secure Messaging Scorecard, detailing various privacy elements of messengers.

[Update; 2014-10-07 – Bleep patch, Telegram, FireChat]
[Update; 2014-11-07 – EFF, surespot]

So in no particular order, here’s a summary of interesting things I’ve come across so far;


  • WickrwickrEnd-to-end encrypted, self destructing messaging, for Android and iOS. Think a secure version of Snapchat.

    • Pros;
      • Multi-platform (Android, iOS first, Others probably to follow later)

      • May use micro-transaction for sub features
  • BleepBleepScreenDecentralised messaging from BitTorrent. Bleep, uses no central server, instead uses a set of ‘nodes’ to connect to the swarm of clients, who can inform each other, of how to reach one another. Once the client has info on other contacts, messages are sent directly.

      • Also allows Voice chat
      • Planned multi-platform (Win 7/8, Android, others to follow)
