Our team: Any cool cat that comes and joins us!
What we're building: Cryptocat aims to provide an open source, browser-based instant messaging service which uses technologies such as client-side cryptography in order to provide stronger privacy than today's leading browser-based IM services. Cryptocat aims to leverage both the ease of use and accessibility afforded by web applications and the security provided by client-side public key cryptosystems.
Who is it for: Everyone who wants to communicate privately, journalists, students...
What we've done at WSJData
* Multi-Party OTR key exchange
* Android native app implemented via Phonegap, routes traffic over Tor anonymity network by default in collaboration with the Guardian Project
* Firefox local webapp in the vein of the Chrome local webapp
* Improved cryptographic primitives (Elliptic Curve Diffie-Hellman, internal browser CSPRNG usage)
* Merged all Cryptocat projects into a single organized repository
* Desktop notifications, improved UI
* Random number generator seeded by dance moves
* Bug hunting
Starting point: Github repo, the combined talents and work of people around the table
