End-to-End Encryption

Encryption

It's like whispering a secret that only your friend can hear — not even the phone or app knows what you said.

Definition

A method of securing data where only the sender and the intended recipient can read the message — not even the service provider has access.

In plain English It's like whispering a secret that only your friend can hear — not even the phone or app knows what you said.

Why this matters

End-to-End Encryption (E2EE) protects your privacy from hackers, governments, and even the companies that provide your apps.

Example

Signal, WhatsApp, and ProtonMail use E2EE to protect messages from anyone else reading them.
