WhatsApp is the worlds largest messaging app in terms of its user base, which is well over a 1 billion users. In India, the app has over 200 million users alone, making it the de facto messaging app for many. But WhatsApp is also unique in the sense that it is one of the few messaging apps to have included end-to-end encryption across the board by default.
The feature went live last year, and basically ensures that WhatsApp messages can only be read by the sender, receiver, and not anyone else. WhatsApp, government agencies, Facebook, nobody can read or see messages sent on the app. In an interaction with Indianexpress.com, WhatsApp Software Engineer Alan Kao and spokesperson Carl Woog highlighted some of the key features of the apps end-to-end encryption.
