The editor will share with you how HTTPS is encrypted. I hope you will gain a lot after reading this article. Let's discuss the methods together.

A lot of the Internet has recently turned to something called the HTTPS protocol. It is a communication way to ensure the security of information between the client and the server by using the public key to encrypt the user data.

HTTP (Hypertext transfer Protocol) usually transmits all data in clear text. This means that anyone who can intercept messages (for example, on the same WiFi network) can clearly read the data sent between the client machine and the server. Includes passwords, credit card data, and other sensitive information. The HTTP protocol has been defined as an insecure protocol, and for this reason, HTTPS encryption occurs naturally.

Technically, HTTPS is not a new transport protocol, it just lays SSL (or TSL) encryption on top of the regular http protocol. TSL/SSL is an asymmetric (public) key encryption mechanism designed to communicate over the Internet protocol. The client and server initially communicate in clear text, determine who they are and exchange public keys, and then finally say, "all right-let's switch to encrypted communication."

HTTPS encryption not only encrypts data to ensure the security of Web connections, but also plays an important role in preventing man-in-the-middle attacks. A website that uses HTTPS encryption actually installs a server certificate on the website server. The browser verifies the identity of the web server by verifying the server certificate. So how can we be sure that this server certificate is valid? The Web website needs to apply for a server certificate through an item certification authority (CA), and the CA authority will not issue the server certificate until it has undergone a rigorous audit. The Web server signs the transmitted data during the data transfer. The browser finally ensures the authenticity of the connection through the signature verification program.
