Secret Behind WhatsApp-End-to-End Encryption

Many of us might be confused and wondering about the new security feature which WhatsApp has released recently. So thought of writing an article and sharing the secrets behind WhatsApp’s end-to-end encryption.

So finally, WhatsApp has implemented end-to-end encryption in order to secure our messages, photos, videos, voice notes etc. Which is really cool ?

WhatsApp’s end-to-end encryption ensures only sender (you) and receiver (the person you’re communicating with) can read what is sent. None other in between, not even WhatsApp will be able to read what you sent.

All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.

What is the “Verify security code” screen in my Contact info/Group info?

Note: The verification process is optional and is used only to confirm that the messages you send are end-to-end encrypted.

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.

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

If you and your contact are physically next to each other…

If the codes do not match, it’s likely you’re scanning the code of a different contact or a different phone number. If your contact has recently reinstalled WhatsApp or switched devices, we recommend you refresh the code by sending them a new message and then scanning the code.

If you and your contact are not physically near each other…

I’m seeing that the messages I send aren’t encrypted?

UPDATE:

At times, you may see the above message in place of what you were sent from a contact. Due to end-to-end encryption, you may need to wait for someone’s message to arrive because their phone needs to come online and properly encrypt the message for you. This can typically occur if you or the person you’re chatting with recently reinstalled WhatsApp.
