End-to-end encryption in Javascript, PHP, and MySQL

End-to-end encrypted chats are more secure than the ones where encryption is done on the server side. Because the messages get encrypted even before sending them to the server. This will prevent any read or altered operation of messages in transit. Let's learn how to do it.

We will be using Javascript for encryption and decryption. And we will be using PHP for handling AJAX requests. All the encrypted messages will be stored in the MySQL database.
