The changes in the conditions of use of WhatsApp, which will occur on May 15, has caused a huge increase in the number of users of alternative messaging applications, such as Telegram, has grown exponentially. Specifically, the tool created by the Durov brothers notified last Sunday a growth of 25 million users new in just 72 hours, which means that the “app” currently has more than 500 million active Internet users around the world.

Despite the fact that, on paper, the application is very respectful of the user’s privacy, since it does not share any data with third parties, does not have end-to-end encryption in conversations, what is the safest according to the experts and it is a tool that if you have WhatsApp. “When we are talking about this encryption, it is assumed that not even the service provider is capable of reading the messages that one user sends to another,” Lorenzo Martínez, director of the IT company Securízame, explains to ABC.

Instead, Telegram uses an encryption based on the MTProto – Mobile Transport Protocol – protocol, which the company said strongly protects conversations. However, if the user does not comply, the “app” does have a functionality that allows end-to-end encryption of messages: “secret chats”.

Secret chats are intended for those who want more security than the average person. All messages in secret chats use end-to-end (end-to-end) encryption. This means that only you and your recipient can read those messages; no one else can decipher them, including us on Telegram. Messages cannot be forwarded from secret chats. And, when you delete messages on your side of the conversation, the app on the other side of the secret chat will have the order to delete them as well, “they explain from the messaging application.

How to do it

To send a message that, for sure, no one else from Telegram will be able to read, you must open the application and look for the contact you want to talk to. After clicking on it, you will see how the conversation opens and the name of the contact and their profile image are displayed at the top of the screen.

You will have to click on the name and you will see how a new screen opens in which are collected in the upper right corner in the case of Android, and in the central part, in that of the iPhone, several icons including a phone, for calls, a camera , for video calls and inverted three dots, which is where you have to “click.” There you will be given the option to select the “secret chat” functionality. Once you start, the service will notify your contact that you want to make a secret chat with him.

The tool also offers to program the self-destruction of messages by clicking on the clock-shaped icon that appears next to the text bar. Options range from 1 second to a week.

You should note that if you use end-to-end encryption, the messages will not be in the cloud, therefore you can only check the conversation from the device that you used to send it. «All secret chats on Telegram are device specific and are not part of the Telegram cloud. This means that you can only access messages in a secret chat from the source device. They are safe as long as your device is safe in your pocket, “they point out from the application.
