"Facebook" launches an additional layer of protection!

Each device contains a private key within the fully encrypted conversation between the two parties, which is used to protect the conversation.

Facebook is adding end-to-end encryption to voice and video calls in its Messenger program, as well as in Instagram messages.

What is full encryption?

End to end Encryption is a term given to messages that are encrypted in the sending device, and decrypted in the receiving device. This feature adds more security and protection to messages that are sent in conversations, and only the sender and receiver can see, hear or read the content of the messages, including the primary company.

How does this feature work?

Each device contains a private key within the fully encrypted conversation between the two parties, which is used to protect the conversation. When you send a message in a fully encrypted conversation between the two parties, your device locks the message while sending it, and this message can only be unlocked by a device that owns one of the private keys for that conversation.

What is the difference between the normal encryption currently found in “Messenger” and “Instagram” and the end encryption?

When we make a call or send a message via “Messenger” and “Instagram”, the message is encrypted in a way that prevents any third party other than the sender and receiver (such as Internet companies or communication interception software and tools) from accessing the content of the communications, as it will appear to them in the form of unauthorized codes understandable. As for the written, audio and video communications, they are readable and exposed to the employees of the Facebook company, and herein lies the danger!

When using end-to-end encryption, the message or communication is encrypted locally on the sending device, and decrypted on the receiving device, so that Facebook cannot see the content of the correspondence, and it will also appear to them in the form of unread codes.

Is the only benefit of end-to-end encryption so that the company does not have access to conversations and correspondences?

When we use the "Messenger" and "Instagram" applications, the communications are saved within the "servers" of the company. This can be seen directly when the account is logged in from a new device. Then, all the old messages on the rest of the devices appear.

In the second case, the correspondence is saved in a special way in the device from which we send it, and therefore when the account is lost or opened from another device, the previous correspondence will not be displayed, which is very useful in case of hacking the accounts, meaning that the person or the hacked party will not be able to From reading previous messages.

Is end-to-end encryption a new feature?

There are many applications that use this feature. Perhaps the most prominent of them are the popular instant messaging applications "WhatsApp" and "Signal".

How do we see old correspondences in "WhatsApp", given that it uses end-to-end encryption?

As for the “WhatsApp” application, the messages are saved in the same device, and they are not saved in the company’s “servers”, but the application allows the ability to backup conversations, so that a copy is placed on your account in “Gmail” or “iCloud”, and thus When you open the app from another device, you can restore the backup normally.

When will this service be activated by "Facebook"?

According to the official announcement from "Facebook", the service will soon see the light without an exact time limit, but gradually in some countries, and for a limited number of accounts, noting that the mentioned service has been available since 2016 in the official application "Messenger", but it is optional!

How can I take advantage of the end-to-end encryption feature that is currently available in the "Messenger" application?

The end-to-end encryption service in “Messenger” works only in applications on the “Android” and “ios” platforms, and does not work in the “web” version. To take advantage of it, the following steps can be adopted:1.Pressing on the compose a new message icon.2.From the top of the screen, choose “Secret.”3.Select the account you want to send the message to.

final summary

Your use of instant messaging applications may expose your sensitive data that you use in correspondence to the owner company or in the event of an account hack. Accordingly, you should think carefully before using any program that does not support the full encryption feature, and not to download applications from outside the official store, and the need to make sure that you always use the latest version.
