JSXC: Adding Encrypted Chat with 3 Lines of Code

If it isn’t on the web, it doesn’t exist. However, most of our current arsenal of web services are provided for free by large international corporations – free as in targeted advertising. More privacy-aware self-hosted alternatives frequently lack the feature set of their commercial rivals, leaving users to decide between privacy and functionality. Therefore, we present WISEchat (Web-Integrated Secure Enhanced Chat), our concept for enhancing practical security for web-based chat, as well as an implementation, the JavaScript XMPP Client (JSXC). By design, JSXC can be easily and painlessly integrated into existing webapps to equip them with encrypted chat capabilities, making them more attractive and thus more frequently providing a secure alternative as the most functional and convenient alternative.
