WhatsApp expands encryption to protect messages

WhatsApp has now fully implemented strong end-to-end encryption on its platform and across all mobile platforms for which it offers apps.

This means users of the latest versions of the messaging app will have their comms and media end-to-end encrypted by default. And there are a lot of WhatsApp users; earlier this year the Facebook owned company announced it had passed a billion active users.

Securing cross-platform video comms was the last piece of the puzzle, according to a WhatsApp spokesman. End-to-end encryption means the content of communications are not stored in plaintext on WhatsApp’s servers. Nor is the company able to decrypt users’ messages to access them since it does not hold the encryption keys. So WhatsApp will be unable to be compelled to hand over messaging data — even if served with a warrant by authorities demanding access.

      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.
