The Facebook-owned service started implementing end-to-end encryption to standard chat messages in 2014, but has now completed rollout to all forms of communication within the app, such as photos, videos and calls.
WhatsApp co-founders Jan Koum and Brian Acton officially announced the rollout on the company's blog:
From now on when you and your contacts use the latest version of the app, every call you make, and every message, photo, video, file, and voice message you send, is end-to-end encrypted by default, including group chats.Encryption has become a hot topic in recent weeks following Apple's high-profile dispute with the FBI, which attempted to compel the company to unlock San Bernardino shooter Farook Syed's iPhone. On March 28 the Justice Department announced it had found an alternate method to gain access to the iPhone in question and dropped the lawsuit.
The idea is simple: when you send a message, the only person who can read it is the person or group chat that you send that message to. No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us. End-to-end encryption helps make communication via WhatsApp private — sort of like a face-to-face conversation.
If you’re interested in learning more about how end-to-end encryption works, you can read about it here. But all you need to know is that end-to-end encrypted messages can only be read by the recipients you intend. And if you’re using the latest version of WhatsApp, you don’t have to do a thing to encrypt your messages: end-to-end encryption is on by default and all the time.
While the FBI has not shared how it was able to unlock the iPhone, nor shared details on what was found, it is believed Israeli mobile software developer Cellebrite, a company that offers "mobile forensic solutions," was enlisted to break into the device. The FBI is still working on analyzing the information found on the iPhone but says it's too early to tell if the data on the device is useful.
Last month, Swiss software developer and civil liberties outfit Proton Technologies released its end-to-end encrypted email app ProtonMail for iOS. Meanwhile, Apple is working to further harden iCloud security so that even it won't be able to access user information stored on its data servers.
