WhatsApp Just Switched on Encryption for a Billion People



Encryption is one of the most important tools governments, companies, and individuals have to promote safety and security in the new digital age. Recently there has been a lot of discussion about encrypted services and the work of law enforcement. While we recognize the important work of law enforcement in keeping people safe, efforts to weaken encryption risk exposing people's information to abuse from cybercriminals, hackers, and rogue states.

Mountain View is home to WhatsApp, an online messaging service now owned by tech giant Facebook, that has grown into one of the world’s most important applications. More than a billion people trade messages, make phone calls, send photos, and swap videos using the service. This means that only Facebook itself runs a larger self-contained communications network. And today, the enigmatic founders of WhatsApp, Brian Acton and Jan Koum, together with a high-minded coder and cryptographer who goes by the pseudonym Moxie Marlinspike, revealed that the company has added end-to-end encryption to every form of communication on its service.


This means that if any group of people uses the latest version of WhatsApp—whether that group spans two people or ten—the service will encrypt all messages, phone calls, photos, and videos moving among them. And that’s true on any phone that runs the app, from iPhones to Android phones to Windows phones to old school Nokia flip phones. With end-to-end encryption in place, not even WhatsApp’s employees can read the data that’s sent across its network. In other words, WhatsApp has no way of complying with a court order demanding access to the content of any message, phone call, photo, or video traveling through its service. Like Apple, WhatsApp is, in practice, stonewalling the federal government, but it’s doing so on a larger front—one that spans roughly a billion devices.

“Building secure products actually makes for a safer world, (though) many people in law enforcement may not agree with that,” says Acton, who was employee number forty-four at Internet giant Yahoo before co-founding WhatsApp in 2009 alongside Koum, one of his old Yahoo colleagues. With encryption, Acton explains, anyone can conduct business or talk to a doctor without worrying about eavesdroppers. With encryption, he says, you can even be a whistleblower—and not worry.

Today more than a billion people are using WhatsApp to stay in touch with their friends and family all over the world. And now, every single one of those people can talk freely and securely on WhatsApp
