The end-to-end encryption of WhatsApp is nothing new, since 2014 they have already begun to encrypt our conversations, but it was limited only to text messages, and not throughout the world. Now the novelty is that encryption reaches everyone and everything we send through WhatsApp.

Thanks to end-to-end encryption the courier service WhatsApp ensures that only you and the recipient can see what you have sent. All our messages, files and our calls are protected with a special code that only your application will know. For greater protection, each message has its own unique code. There will be no way to disable end-to-end encryption.

If WhatsApp informs us with the previous message that our conversation is encrypted, it is that both we and our receiver have one of the latest versions of WhatApp and it is already you have enabled peer-to-peer encryption, although they allow us to manually confirm if a chat is encrypted by showing some codes.

Confirm security code

The codes are unique for each chat and they can be compared between the recipients of your messages to confirm that the messages you send to that chat are end-to-end encrypted. To confirm if a chat is end-to-end encrypted, we just have to:

  1. Open a chat.
  2. Press on the name of the contact or group to then go to the information screen.
  3. Press Encryption to see the QR code or all 60 digits.

If the QR code and the 60 digits of the code is that that conversation is being encrypted. WhatsApp allows us to make sure by checking if that code is valid, although this step is totally optional. For this we have two options, scan the code that our contact shows us or that our contact scan our code. If the chat of our contact is protected we will get a verification. We can share our code with our contact so that we do not have to do the verification in person.

Unencrypted chats

If any of our contacts still have a very old version of WhatsApp, the chat with that person will not be encrypted, when we go to see the security code we will see the notice that the conversation is not being encrypted for that reason.

On Account> Security we can activate the security notifications, which will notify us when the security code of a contact has changed. This setting does not affect encryption.
