What is ChatSecure?

ChatSecure is a free and open source messaging app that features OTR encryption over XMPP. You can connect to your existing accounts on Facebook or Google, create new accounts on public XMPP servers(including via Tor), or even connect to your own server for extra security.

Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OTR and XMPP, such as Adium, Jitsi, and more.

ChatSecure only uses well-known open source cryptographic libraries to keep your conversations private. Other apps may make claims about 'military grade' security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.

  • XMPP with TLS certificate pinning.
  • OTR for verifiable end-to-end encryption and forward secrecy.
  • OMEMO for a mobile-friendly alternative to OTR.
  • Tor to help bypass restrictive firewalls.
  • SQLCipher to locally encrypt conversation logs.

I'm using this new open-source messaging client by the GuardianProject for a few weeks now and it works great! You can couple it with the Tor network Proxy Orbot (by the same authors) to have a fully open-source and anonymous communication suite on your Android device. (There's a tiny issue with Orbot though: To close it, I have to go in the app list and kill it, because after successfully establishing a connection to the Tor network, its UI is broken and keeps flashing as if it is redrawing the UI a couple of times every second... but doesn't affect functionality)

Don't forget to always manually establish a secure/private connection before chatting!

Tested it with PC (Linux and Win) users of Pidgin (Don't forget to install the OTR (Off-The-Record) Plugin for Pidgin!) and Adium for MacOS. iPhone users can use ChatSecure, but the connection won't be over Tor, so iPhone users loose meta data anonymity... (I.e., the chat itself will be encrypted, but the facts that you're chatting and how often and when you receive a msg will theoretically be detectable.)

Take that PRISM ;)
