What is end-to-end encryption in WhatsApp in simple words - briefly?
End-to-end encryption in WhatsApp ensures that only the sender and receiver can read messages. This means not even WhatsApp or third parties can access the content of your communications.
What is end-to-end encryption in WhatsApp in simple words - in detail?
End-to-end encryption (E2EE) in WhatsApp is a security feature that ensures only the people communicating can read what is sent, and nobody in between, not even WhatsApp itself. Here's a detailed breakdown:
-
Locking the Message: When you send a message on WhatsApp, it's 'locked' with a unique padlock and key known as encryption keys. These keys are generated by your phone and never leave it.
-
Sending the Lock: Instead of sending the original message, WhatsApp sends the lock (encrypted message) to the recipient. This lock can only be opened with the right key.
-
Delivering the Key: The encryption keys are sent separately and securely to the recipient's phone. Only the recipient's phone can unlock the message because it has the unique key.
-
Reading the Message: Once the recipient's phone receives the lock (encrypted message) and uses its unique key to unlock it, the original message can be read.
This process happens every time you send a message on WhatsApp. It ensures that even if someone intercepts your messages, they won't be able to read them without the unique key. This is why end-to-end encryption is crucial for protecting your private communications.
