What is End-to-end Encryption, and Why You Should Use It?

 Over 560 billion text messages are sent every month worldwide, including yours. But did it ever occur to you that someone else might be able to access your correspondence? Have you ever asked yourself whether they read specials? services and large companies my messages? If your fears come true, then you used the messenger without end-to-end data encryption.

What is End-to-end Encryption

According to the Google dictionary, encryption is the method of altering information or data into code to prevent unauthorized access. If we look at it through the prism of instant messages, then end-to-end encryption E2EE (End-to-end encryption) is a transmission system where only the sender and the recipient can access the sent messages. End-to-end or end-to-end encryption means that the message is encrypted on the user's device, sent encrypted, and decrypted on the recipient's device. In this case, third parties will not receive your data. Neither telecommunications companies, nor messengers, nor Internet providers will be able to access the correspondence, because instead of the message, you get encrypted gibberish like D! G012s%). Gpl23 which is almost impossible to decrypt. 

How Do Encrypted Messages Work?

As mentioned above, encrypted messages work with an encrypted code like D! G012s%), gpl23 \, or a cipher in terms of cryptography. Each user has two keys. Public and private. Let's say you are Bogdan and want to send a text to Veronica. You will see Veronica's public key available to everyone in order to encrypt the message with it. You send your message “Hello, how are you”. Your phone encrypts the message with Veronica's public key and sends it to the server. The server redirects the message to Veronica. Veronica receives it on her device and decrypts it with her private key. Thus, the entire data transfer process is secure, and even if you have access to the server - the maximum you can get - an encrypted message that is almost impossible to decrypt since you do not have a private key.

Why You Should Use End-to-end Encryption

If you are worried that someone is reading your text messages, you need an app that encrypts all of your data. Applications that use the E2EE end-to-end encryption system will protect your data from third parties including hackers. Encrypted messages will make it impossible to access your correspondence. Even if they get access, they won't be able to read your messages. So before you write to your friends, make sure that your VoIP application supports end-to-end encryption to get rid of the risk of hacking your correspondence by hackers and special structures.
