Cryptocat is indebted to Paul Brodeur, David Mirza, Hasan Saleh and Tina Salameh.Cryptocat, the popular open source application that enables users to chat online easily and securely, is now available for iPhone users (on Apple’s App Store), as well.Ĭryptocat initially took the form of a web app for Mac OS X and browser extensions for Chrome, Firefox, Safari, and Opera, but last December the team behind it publicly released the source code for Cryptocat for iPhone and Android and invited the security community to review it and help find security bugs. It uses parts of the crypto-js library and the Bitcons iconset. Those wanting to set up similar functionality should consider writing something similar.Ĭryptocat™ is a trademark of and is developed by Nadim Kobeissi. On the production server, it's actually a cron job that checks the modification time of chats and wipes them securely. The code for secure deletion of idle chats after one hour is not included in the Cryptocat git repository. We severely warn against deploying Cryptocat without HTTPS, unless the deployment is occurring as a Tor Hidden Service. Using Cryptocat without HTTPS in a production environment is a recipe for disaster. Think responsibly if you are in extreme, life-threatening situations. Important notesĬryptocat provides strongly encrypted, secure communications. Run make build-chrome-zip in order to generate a Google Chrome-loadable.zip.Configure settings inside src/server/index.php.make.sh inside the src/server/js/src/ directory in order to generate the client-side cryptography code (requires gcc.) If your server does not support symlinks, replace the symlinks with copies of the actual files accordingly.WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
