Tor Project has released the beta version of its Tor Messenger, which, as you’d expect, is a chat client which brings anonymous, “off-the-record” chats based on Tor’s secure browsing system. The new Tor Messenger is actually based on Instantbird, an instant messaging client developed in the Mozilla community. The technology used to develop the app is built on Instantbird but all the traffic is being routed through Tor. The chat client works cross-platform and it supports a wide variety of transport networks, including Jabber (XMPP), IRC, Google Talk, Facebook Chat, Twitter, Yahoo, and others. The beta release was more than a year in the making, so this isn’t just a side project from the developing team. Speaking with Wired, Tor public policy director Kate Krauss said the following: You can download the Messenger for Linux, Windows and OS X directly from the TorProject.org website. Do take into account that this is a beta release of Messenger, so there could be bugs related to the overall usability. Furthermore, Sukhbir Singh, one of the developers of the Tor Messenger project, said that “people shouldn’t rely on this version for strong anonymity.” The team said their current focus is one security, robustness and user experience but future updates could bring such options as reproducible builds for Windows and OS X, sandboxing, automatic updates, improved Tor support, OTR over Twitter DMs, internationalized builds, secure multi-party communication (np1sec) and encrypted file-transfer.
