At least five years ago we began to see that, when entering WhatsApp, the first screen that appears is the app’s default background and the message ‘End-to-end encryption’. Since then it has been said that the messages we send and receive are protected, but how does it work? Is it really safe?
Yes, clearly this function was integrated into WhatsApp and many other applications in order to protect your privacy. This prevents other people from accessing your messages, that is, it will only be visible to you and the recipient. That means that neither the government officials, the manufacturer of your phone or the Internet company you use will be able to see what you chat.
And it is that his process does not leave much room for error. The function allows the application to take your message, “confuse” or “scramble” it, take it to your recipient and organize it again there. So if any hacker or company wants to access your conversations they will be met with a bunch of jumbled letters instead of a proper message.

Currently applications like Instagram do not have this function, so it is very likely that the messages you receive and send there pass through several hands. As we mentioned, the developers of the application or your internet service may be involved, who will be able to access the information more easily. And it is that, in the past, end-to-end encryption used to be exclusively for techies and elite people. Over the years, the function was deployed to the rest of mortals, until it reached WhatsApp, one of the most used apps in the world.
However, you should keep in mind that end-to-end encryption only protects your messages. That is, data such as the date, time, and sender and recipient will be visible to whoever has the ability to access them. There are quite a few apps that offer this security for those who want to keep their privacy secure.
