What is End-to-End Encryption?
End-to-end encryption (E2EE) protects data so that only the sender and intended recipient can read it. The content is encrypted at the point of sending and only decrypted once it reaches the recipient.
How does End-to-End Encryption work?
The process relies on a key pair system:
- The sender encrypts the message using the recipient’s public key.
- Only the recipient can decrypt the message with their private key.
- No intermediary has access to the content at any stage.
Benefits of End-to-End Encryption:
- High security
- Data integrity
- Protection against surveillance and manipulation
Use Cases:
- Messaging services
- Encrypted email
- Remote access and VPN
- Critical infrastructure
