What is https for a website and why should we use it?

Since the epidemic period, online promotion has become more and more important, and all walks of life have started the cloud + mode to assist people in dealing with various matters. I don’t know if you have noticed that in recent years, the Internet has ushered in the "HTTPS encryption era", and more and more corporate official websites are using HTTPS as the mainstream protocol. So what is https on the website and why should we use https? Let’s follow Feng Chao from Jimifeng Technology to learn more about it!

What is https for a website and why should we use it?

Introduction to HTTP

HTTP is the most widely used network protocol on the Internet. By using a web browser or client to initiate an HTTP request to a specified port on the server (the default port is 80), hypertext is obtained from the website server to the local browser. In layman's terms, from entering the domain name to displaying the website content on the computer screen, the process of an HTTP request is completed.

Introduction to HTTPS

HTTPS is an HTTP channel that aims at security. Simply put, it is a secure version of HTTP. The security foundation of HTTPS is SSL. The main functions of the HTTPS protocol can be divided into two types: one is to establish an information encryption channel to ensure the security of data transmission; the other is to authenticate the authenticity of the website and prevent "phishing" websites.

Why is HTTPS more secure than HTTP?

All data transmitted via HTTP protocol is unencrypted. For example, when you visit a website, the search keywords, account passwords, etc. are visible when passing through intermediate links such as routers and broadband access providers. Therefore, it is extremely unsafe to use the HTTP protocol to transmit private information. In order to ensure that these private data can be transmitted in encrypted form, the SSL protocol was designed to encrypt data transmitted by the HTTP protocol, and thus HTTP was born.

Simply put, the HTTPS protocol is a network protocol built by the SSL+HTTP protocol that can perform encrypted transmission and identity authentication, and is more secure than the HTTP protocol. It can be understood that the client encrypts the data and sends it to the server, and the server decrypts it to obtain the data, and vice versa. During this process, the data is encrypted with a key so that even if the content is hijacked in the middle, it cannot be cracked without the key.

In this link, in order to verify whether the server is the real server you want to visit, a third party is needed to check. This third party is called CA (certificate authority, which is the abbreviation of digital certificate certification center. As an independent third party, its function is to verify the identity of the website and ensure that the authorized person who obtains the certificate is the owner of the website rather than an impostor individual or organization).

Practical Application

In actual work, we also recommend enterprises to adopt the HTTPS protocol to keep up with the development of the Internet, such as: Xiaolongkan Hotpot official website, Quanyou Home Furnishing official website, Walaida official website, etc. For more Guangzhou website construction cases, please visit our case center.
