If you’re a user of WhatsApp, you may have noticed that messages sent out yesterday were preceded by : ‘Messages you send to this chat and calls are now secure with end-to-end encryption.’
The popular messenger app rolled out an update that means that every call and text will protected with strong encryption.
This means that millions of conversations cannot be accessed by the authorities, even if WhatsApp are facing a court order.
WhatsApp founder Jan Koum said: “The desire to protect people’s private communication is one of the core beliefs we have at WhatsApp, and for me, it’s personal. I grew up in the USSR during communist rule and the fact that people couldn’t speak freely is one of the reasons my family moved to the United States.”
The update works on all devices – iPhones, Google Android devices, Nokias and Blackberry devices – running the latest version of app.
In group messages if one user is running an older version of the app, the other users in the group will be able to tell which person is causing the message to be unencrypted.
“All you need to know is that end-to-end encrypted messages can only be read by the recipients you intend,” WhatsApp said.
