One of the novelties that have more recently been implemented on WhatsApp is extreme encryption to extreme, which uses a series of public and private keys so that only the sender and the receiver are able to read the messages in the conversation, leaving these out of the reach of other users with the Organization itself.

While both users to have a recent version of the official client of WhatsApp, this encryption is activated by default to all conversations and won’t turn off, however, the encryption keys can change for various reasons, so in this article we will see how we can receive notifications in chats whenever you change the encryption code and how to verify that key.

The first thing we have to do is open the menu of WhatsApp settings and access the “Account” section.

Several configuration options related to it, for example, the options of privacy, of which we have spoken above, the possibility of changing phone number, delete the WhatsApp account and which we are interested, “Security” appear us within “Account”.

Click on this entry and will see a new screen such as the following.

At the bottom a message us that allows us to decide if we want to show a notification in the notifications each time you change the encryption key, where, for example, change the other person’s phone, format it or delete the data and log on again.

Although using the above options, we can check the status of WhatsApp general encryption, we can also check specific encryption of each conversation. To do this, the only thing we have to do is open a new conversation and click on the name of the user (at the top) to open the information window.

Here you will see an option called ‘encryption‘. This option will be shown with a closed padlock in green indicating that the conversations with this user are being encrypted. If we click on that paragraph can see a QR code and encryption key 60 digits.

This is the key that you are encrypting messages. We can do the same with the chat of the other person and see how the key matches or simply scan the QR with the same purpose.
