End-to-End Encryption (E2EE) ensures that data is encrypted on the sender’s device and decrypted only on the recipient’s device. No intermediaries—including servers, service providers, or network operators—can read or modify the content in transit. In an E2EE model, encryption keys are generated and stored at the endpoints. Even if data passes through multiple servers, it remains unreadable without the recipient’s private key. This design protects against data breaches, man-in-the-middle attacks
