WhatsApp has started to include a new feature in its application, in all versions of its application, and that will apply to all users who use said app. We are talking about end-to-end encryption. The novelty is that it is not something that must be activated, but WhatsApp will try by default that all conversations and groups are encrypted so that they can only be read by participating users.
WhatsApp launches a novelty for its application that will reach all users and all versions of the app. Not only to the Beta, but also to the version available on Google Play and of course to the version available on other platforms, such as the iOS app. It’s about end-to-end encryption of conversations. This means that only users who send and receive messages in conversations or in groups can see those messages. These are encrypted, they travel encrypted through WhatsApp servers and throughout the Internet, and are decrypted when received by the user or users receiving the group in question. Thanks to this, we can send messages confidentially.
To confirm that end-to-end encryption is activated, we just have to go to a chat window, click on the name of the contact or group to see its information, and then select Encryption. Now compare this data with that of the chat user you have selected, or with one of the users of the group you have selected. The 60 numbers should be the same. And the QR code too, which you can scan from that same section.
If the code is not the same, you have probably made a mistake and the numbers do not match, it is that you have chosen a chat that is not that of the other person with whom you are comparing the number. A novelty that now comes to WhatsApp for all users and for all versions.
