WhatsApp rolls out full end-to-end encryption
All messages on the world’s most popular Instant Messenger are now encrypted. WhatsApp announced today that they have completed an integration that has lasted for nearly a year and a half. As of today, the integration is fully complete. Users running the most recent versions of WhatsApp on any platform now get full end to end encryption for every message they send and every WhatsApp call they make when communicating with each other. This includes chats, group chats, attachments, voice notes, and voice calls across Android, iPhone, Windows Phone, Nokia S40, Nokia S60, Blackberry, and BB10. Update your WhatsApp client to the latest available version and you’ll notice the ecryption.
Over a billion monthly active users across the world are now using the Signal Protocol for end to end encryption. Over the next year, we will continue to work with additional messengers to amplify the impact and scope of private communication even further. We’re excited about the future of the Signal Protocol and the places it is going
By default, WhatsApp users have the option to verify the authenticity of their encrypted session. This can be done by either scanning a QR code or by reading a string aloud. The WhatsApp team has been slowly rolling out security services since November 2014 at least, when it announced end-to-end encryption for text messages on Android.
Open Whisper’s protocol is open source, and the group has pledged to help other messenger services employ the same protections going forward. “Over a billion monthly active users across the world are now using the Signal Protocol for end to end encryption,” Open Whisper wrote in its blog post announcing the change. “Over the next year, we will continue to work with additional messengers to amplify the impact and scope of private communication even further.”
