Easy to use encrypted instant messaging built on modern web technologies
We are pleased to announce that Cryptocat for iPhone and Android has reached public beta. Before we release Cryptocat for iPhone and Android on the App Stores for the general public, however, we are giving the security community and experts the opportunity to review Cryptocat’s mobile source code for ten days, and report any bugs or security issues they discover.
“OUR MISSION HAS ALWAYS BEEN ON MAKING ENCRYPTED
CHAT FUN AND EASY TO USE, FIRST AND FOREMOST”
You may browse the complete code at our GitHub repositories:
If you discover a bug or a security issue, please report it! You may report it by opening an issue. All reports for valid bugs will be properly credited, and rewards may be involved in the shape of Cryptocat t-shirts, stickers, and even cash for particularly impressive and useful finds. Thank you for helping make private chat accessible and safe for everyone!
Cryptocat is an experimental browser-based chat client for easy to use, encrypted conversations. It aims to make encrypted, private chat easy to use and accessible. We want to break down the barrier that prevents the general public from having an accessible privacy alternative that they already know how to use. Cryptocat is currently available for Chrome, Firefox and Safari. It uses the OTR protocol over XMPP for encrypted two-party chat and the (upcoming) mpOTR protocol for encrypted multi-party chat.
