Encryption & Security

What Is End-to-End Encryption?

Encryption where only the sender and recipient can read the message - no intermediary can.

In end-to-end encryption, data is encrypted on the sender's device and decrypted only on the recipient's device. Neither the service provider nor any intermediary server holds the key to read the content - this is widely used in messaging apps.
