WhatsApp, the world’s most popular instant-message service app with more than 1 billion users, is now fully encrypted on all platforms: Android, iPhone, Blackberry and others.
“Whatsapp’s roll out of the Signal Protocol, providing end to end encryption for its one billion users worldwide and is a major boost for people’s ability to express themselves and communicate without fear,”
With end-to-end encryption, messages are scrambled as they leave the sender’s device and can only be decrypted by the recipient’s device. File transfers and voice calls would be encrypted too. The Facebook-owned company said protecting private communication was one of its “core beliefs”.
“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,” WhatsApp co-founders Jan Koum and Brian Acton wrote in a blog .
Users with the latest version of the app were notified about the change when sending messages. The setting is enabled by default.
“This is a huge victory for privacy and free speech, especially for activists and journalists who depend on strong and trustworthy communications to carry out their work without putting their lives at greater risk.”
