Editor to share with you what the role of HTTPS, I hope you will learn a lot after reading this article, let's discuss it together!

What is HTTPS?

When we use a browser to visit the site (home page), the browser will now display the site page address in the address bar.

URL usually starts with http, but now you may find that the page addresses of many e-commerce sites already start with https. So why does URL start with "http" and "https"?

First of all, we have to explain that URL,URL generally consists of two parts, the communication protocol and the full domain name, as follows.

The domain name is easy to understand, that is, the address path to the website. The Web page is determined by the full domain name and different page content is returned to the client browser. So what is the communication protocol?

Communication protocol

Communication protocol is a communication rule used for data transmission between browser and server.

Communication protocols are like the language that people speak. Both sides of the communication need to determine a unified language in order to communicate effectively. There are actually two communication protocols between Web server and browser, which are http and https.

HTTP protocol

HTTP protocol is a very popular web protocol at present, and HTTP protocol has always been the mainstream communication protocol of web pages. However, there is a serious security problem in HTTP protocol, that is, HTTP protocol adopts plaintext data transmission mode.

Take the online login function as an example, the user enters the personal account number and password on the page, and then clicks the login button to submit to the server. The server receives the user's account password and then logs in to the system. There seems to be no problem at all, but the HTTP protocol is transmitted in clear text. If in the process of data transmission, the data is intercepted by a third party, then the user's account password will be fully known by the interceptor. If the user's operation is not to log in, but to pay online, then what the interceptor gets will be the user's bank account and password.

HTTPS protocol

HTTPS protocol adds "S" to HTTP protocol, which means "encryption" and "secrecy".

HTTPS protocol no longer uses data plaintext transmission, but encrypts the submitted data before data transmission, and then transmits the encrypted data (ciphertext) to the website server. In this way, because the data at the time of transmission is ciphertext, even if it is intercepted by a third party, the interceptor can not interpret the data content, which can well protect the security of user data.

In today's era of Internet development, HTTPS protocol is undoubtedly a better solution than HTTP protocol, and HTTPS websites are bound to completely replace HTTP websites.

What are the functions of HTTPS?

In fact, HTTPS website in addition to encrypting user data, there are other functions.

Protect customers' private information

Because the HTTPS protocol encrypts the transmitted data, it can well protect the customer's private information from being disclosed.

Verify the identity of the website

The SSL certificate used by the HTTPS website can only be issued through strict identity authentication, which can ensure the authenticity of the website and effectively prevent phishing websites.

Prevent web pages from being tampered with

Through encryption and signature technology, SSL certificate can prevent data from being tampered with in the process of network transmission and ensure the security of users.

Better user experience

Major browsers around the world have vigorously promoted the HTTPS protocol, and the HTTPS website will have a "security lock" icon in the browser address bar to make users more confident.

Improve the ranking of search engines

Both Baidu and Google have made it clear that HTTPS sites will be used as an important weight in search rankings.

What are the brands of SSL certificates?

To provide the HTTPS protocol, a SSL certificate must be installed and deployed for the Web web server. At present, there are many well-known SSL certificate brands around the world, which can provide good SSL certificate services. At present, the more well-known foreign SSL certificate brands are: GlobalSign, DigiCert, GeoTrust, Symantec, Comodo, Entrust and so on, while the domestic more well-known SSL certificate brands are OKCERT, CFCA, TrustAsia and so on.

What is the price of the SSL certificate?

The prices of different types of certificates vary greatly. Generally, SSL certificates can be divided into EV type, OV type, DV type and wildcard type, while the prices of SSL certificates vary among different certificate brands. Generally speaking, the price of the more well-known certificate brand will be slightly higher, and the price of domestic certificate brand will be relatively cheap. The following is the price list of SSL certificate on this website. For more information, please click on the price of HTTPS certificate.
