WhatsApp Turned on End-to-End Encryption By Default For Its All Users









WhatsApp has always prioritized making your data and communication as secure as possible. And today, we’re proud to announce that we’ve completed a technological development that makes WhatsApp a leader in protecting your private communication: full end-to-end encryption. 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.


WhatsApp is updating its messaging app so that every text message and voice call will be encrypted for the company’s one billion users.


Yes, Whatsapp has finally implemented full end-to-end encryption, as promised a year ago.
This means, from now every message, image or voice call you made will be secured by end-to-end encryption so that only you and the person you’re communicating with can read the content of the message, and nobody in between, not even WhatsApp.




In other words, this also means that WhatsApp would not be able to comply with any court order that demands access to the content of any conversation happens over its service.
Starting today, you will see a notification on your WhatsApp conversation screen as your messenger becomes end-to-end encrypted, as shown in the screenshot.


“This is because your messages are secured with a lock, and only the recipient and you have the special key needed to unlock and read them,” Whatsapp says.


Additionally, you will be able to see a small lock icon below the profile of the recipient that ensures your conversation is secured with encryption.
“All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages,” the company adds.






What is the Verify security code screen in my contact info/group info ?
This verification process is optional and is used only to confirm that the messages you send are end-to-end encrypted or not.

This code can be found in the contact info/group info screen, both as a QR code and a 60-digit number. These codes are unique to each chat and can be compared between people in each chat to verify that the messages you send to the chat are end-to-end encrypted. Security codes are just visible versions of the special key shared between you – and don’t worry, it’s not the actual key itself, that’s always kept secret.



How to verify if someone is trying to spy on your conversation?
Well,  the latest version of WhatsApp mobile application offers you an option to verify the keys of the other users with whom you are communicating, ensuring prevention from the man-in-the-middle attack.
Whatsapp key verification can be done by scanning a QR code, or by comparing a 60-digit number, under newly introduced “verify security code” option in the WhatsApp.
“WhatsApp users can opt in to a preference which notifies them every time the security code for a contact changes.”


About a year ago, Facebook partnered with ‘Open Whisper System’, company behind the popular Signal and TextSecure encryption apps, to integrate the Signal’s Open source strong encryption protocol into WhatsApp messaging app.
However, there is one point to be noted that if several users are sending texts in a group chat and one of the users is running an older version of WhatsApp that doesn’t support encrypted messages, all the conversation going through that group chat will remain unencrypted.


To Verify that a chat is End to End Encrypted ?

  • Open the chat.
  • Tap on the name of the contact or group to open the contact info/group info screen.
  • Tap Encryption to view the QR code and 60-digit number.

If you and your contact are physically next to each other, one of you can scan the other’s QR code or visually compare the 60-digit number. If you scan the QR code, and the code is indeed the same, a green checkmark will appear. Since they match, you can be sure no one is intercepting your messages or calls.

If the codes do not match, it’s likely you’re scanning the code of a different contact, or a different phone number.
