What is End-to-End Encryption?
E2EE
It is a security method in which messages can only be read by the sender and the recipient, and no one in between can see the content.
Overview
End-to-end encryption is the process of locking data as soon as it leaves your device and can only be opened with the target person's key. Thanks to this method, service providers or third parties carrying the data can never see your content. It is one of the most basic shields that protect your privacy in the digital world.
How it works
When you write a message, your device converts it into a complex code. This code remains encrypted as it passes over the internet. When it reaches the recipient's device, it is converted back into readable text with a special key that only the recipient has.
Where it is used
It is used in messaging applications such as WhatsApp or Signal, secure file transfers and privacy-oriented cloud storage services.
Commonly confused with
It differs only from encryption between you and the server; Here even the server cannot see the content.
