All users of WhatsApp who have updated to the latest version of the messaging application already have a extra layer of security in your conversations We are referring to the end-to-end encryption that the company now applies to both written messages such as calls, photos and videos shared and even documents sent. Something that ensures that not even those responsible WhatsApp, neither cybercriminals, nor hackers, nor governments can interfere and read or listen to user communications.All this thanks to a unique code that only the interlocutors of a chat know, and whose validity can be confirmed to ensure that everything that is said in said conversation is totally safe
Thus, users who are most concerned about their privacy should update their WhatsApp to the latest version available for Android, iOS, Windows Phone, Symbian (if anyone is still using it) and BlackBerry This will ensure all the contents that come out of your terminal. However, even though this protection is applied automatically, WhatsApp has added a way to confirm that the security key that each chat has is correct, without there being any security breach in the communication. This code is unique for each conversation, and although it is not the key that allows you to decrypt messages, it is really valuable to confirm that everything is secure.
To confirm it is necessary to scan a QR code or compare the 60-digit numerical code. For this, it is possible to do it in person, when the two interlocutors of the same chat are in the same physical place, or at a distance.
In case of doing it in person, just click on the name of the conversation, at the top of the chat, to access the Information screen Here a message informs if the other person is protected by the encryption of WhatsApp If this is the case, you can click on this message to perform theconfirmation of the security code At that moment the QR code and the 60 digits appear on the screen, arranged for the other person to follow the same steps, click on the scan code button and use your mobile camera to confirm the code on the screen of the other user .
In the second case, if people are not around to perform the verification, it is possible to follow the same steps to access to the QR code screen In this situation, the user can click on the share button at the top right of the screen, choosing the route by which they want to send said code, both in QR format and the list of 60 digits, to the other person. This way, caller can scan the QR code or compare the 60 digits as they see fit.
When making this confirmation, and if everything went well, both users will be able to see a green check on their screens. This means that the communication is totally secure, being able to affirm that the code matches and that, therefore, the encryption or new security barrier is carried out correctly.
Now, making this confirmation is not mandatory to be protected, since WhatsApp applies your encryption by default to all But it does help to give users more peace of mind and ensure that no one is eavesdropping on their conversations.
