No code from Facebook is loaded or executed within Cryptocat, and the login procedure happens in a sandboxed window, Kobeissi wrote.Ĭryptocat version 2.2 is available for Chrome, Safari and Opera. 'Such an approach would have made encrypted chats over Facebook even more immediate, but would have immersed Cryptocat into Facebook's network and runtime environment in a way that didn't satisfy our security precautions,' he wrote.Ĭryptocat connects to Facebook as an XMPP client over its outbound BOSH relay. If one party does not have Cryptocat installed, the two people may chat, but the text will not be encrypted.Ĭryptocat opted not to integrate itself directly into the Facebook chat interface to maintain 'layers of separation,' Kobeissi wrote. Kobeissi wrote that if a person's Facebook friend logs into the service and is using Cryptocat, the conversation is automatically upgraded to an encrypted one.

'The usability benefits of being able to quickly see which friends are online and ready for an encrypted chat remain overly substantial for those users.'įacebook will know, however, that the people are using the application due to the use of a Cryptocat relay to transfer the contacts list, he wrote. 'There's no harm in Cryptocat using this already-given metadata to allow these users to set up encrypted chats,' Kobeissi wrote. Users presumably know they're divulging that information already to Facebook by using their service.

The fact that Facebook knows two people are chatting, a type of information known as metadata, should not be a deal breaker, Kobeissi wrote. But the messages themselves will only say. If two people are using Cryptocat, Facebook will know an exchange occurred between the two users and the time of their chat.
