WhatsApp Conversations Now Totally End-to-End Encrypted

April 7, 2016, By Sanjeev Ramachandran

Facebook, the parent firm of WhatsApp, was among the few tech firms that stood by Apple when the latter’s battle with FBI got gripping. And now, the company has decided to step up the game through WhatsApp, one of the world’s most used chat platform.

Back in November 2014, WhatsApp has revealed that it will be pushing for the encryption technology to make sure that conversations get totally encrypted in the chat platform. It later introduced end-to-end encryption for text messages. Now, WhatsApp has announced that the platform is completely end-to-end encrypted.

It means that all the conversations, including videos, images and calls, shared through WhatsApp will remain accessible to only the one who sent it and one who receives it. The latter can also be a group of contacts if the conversations are shared to groups.


Access to these conversations will be forbidden to any third-party person, which includes regimes, hackers and also WhatsApp itself.

Any user who gets the latest update of WhatsApp will now have end-to-end encryption enabled in their devices, provided the recipients of a conversation also gets the latest version.

Every message sent through the latest version of WhatsApp is encrypted in default, and users won’t have to start a separate secret like in Telegram chat or change any settings to have it turned on. The option to turn off the encryption has also not been provided, explains the company blog.

Each message on WhatsApp will have its own Message Key Generated that also cannot be reconstructed from the sessions. The Message Keys are generated using AES256 in CBC mode for encryption and HMAC-SHA256 for authentication.

Users can verify the encryption by means of QR code scanning through the accounts that are to be verified by tapping the view more option in the encryption alert message.

The move is expected to be facing a wider disapproval from the FBI and Justice Department, as WhatsApp has apparently followed the footsteps of Apple in rebuffing the FBI stance.

Currently, more than one billion users are subscribed to the services of WhatsApp throughout the globe. As of now, there haven’t been any comments made by the Federal organizations.
