End-to-end message encryption is an enhanced security feature for your chats. But how does it work, and why is it important? Let’s find out.
1 What is End-to-End Message Encryption?
End-to-end message encryption is an advanced security feature that ensures the integrity of your messages. When enabled, messages are encrypted before being sent and remain encrypted during transmission and receipt.
Only the devices owned by the sender and recipient can decrypt the messages. This enhances the security provided by end-to-end encryption over current message encryption methods.

2 How Does End-to-End Message Encryption Work?
Encryption Before Sending:
Before a message is sent, its content is encrypted on the sender’s device. This process converts the message into an encrypted form, protecting it from being read during transmission.
Sending to the Zalo Server:
The encrypted message is then sent to the Zalo server. This server acts as an intermediary during the message transmission between the sender and recipient.
Forwarding the Encrypted Message:
The Zalo server forwards the encrypted message to the recipient’s device, maintaining the security of the message by keeping it encrypted.
Decryption on the Recipient’s Device:
The encrypted message is decrypted on the recipient’s device, converting it back to its original content. This process occurs only on the recipient’s device, ensuring that only they can read the message.
