WhatsApp Messenger is a cross-platform instant messaging application that allows iPhone, BlackBerry, Android, Windows Phone and Nokia smartphone users to exchange text, image, video and audio messages for free. WhatsApp is especially popular with end users who do not have unlimited text messaging. In addition to basic messaging, WhatsApp provides group chat and location sharing options. Technically speaking, WhatsApp uses a customized version of the open standard Extensible Messaging and Presence Protocol (XMPP). WhatsApp Inc. was founded in 2009 by Brian Acton and Jan Koum, both veterans of Yahoo.

It has added end-to-end encryption to all of its messages – meaning that the company couldn’t give information to governments, even if it wanted to. The latest version of the app will use security technology that means that messages can’t be intercepted as they travel between devices.

WhatsApp encryption uses a 256-bit key, the AES256 algorithm is accepted by the US and Canadian governments as standards for encrypting transited data and data at rest, which is only known to the sender and recipient, which is why the security is described as “end-to-end”. “From now on when you and your contacts use the latest version of the app, every call you make, and every message, photo, video, file, and voice message you send, is end-to-end encrypted by default, including group chats,”

“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,” WhatsApp wrote. “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.”

STEP 2: Now open the latest WhatsApp installed on your Android or iOS device.

STEP 3: Open any chat on your WhatsApp.

STEP 4: As soon as you open the chat screen, you will find the option “Messages you to send to this chat and calls are now secured with end-to-end encryption. Tap for more info”.

STEP 5: Tap the above-mentioned message in your WhatsApp chat screen. As soon as you tap it, it will ask you for verification.



STEP 6: Now,tap the Verify button, and it will show you a QR code that has to be scanned.

STEP 7: You will either have to scan the QR code on your contact’s phone, or you will have to ask them to scan your code. You will have to do the same process on your recipient’s device to reach the QR code scanning stage i.e. step 1 – 6.
STEP 8: Once you’re done scanning the code, you will find an end-to-end encryption indicator in the contact info or the group info in your WhatsApp Messenger.
We’ve updated our Secure Messaging Scorecard to give WhatsApp 6 out of 7 stars. Unfortunately, WhatsApp remains closed source, which means that an independent reviewer can not review the code and its security. For this reason, if you’re using Signal to communicate with contacts already, keep it. It’s better to use a fully free and open source product. But because of the wide adoption of WhatsApp, you may have contacts you would have never expected using end-to-end encryption already. For the sake of their and your privacy and security, install WhatsApp and use it when communicating with them.
