What the editor shares with you today is what is the working principle of HTTPS? What is the role, many people do not understand, today, in order to let you know more about HTTPS, so give you a summary of the following content, let's look down together. I'm sure you'll get something.

When it comes to HTTPS, I believe most people will not feel strange. Although HTTPS is no longer a new agreement, it has been implemented by many large Internet companies in recent years. We can also see that HTTPS will become a major development trend in the future.

1. The definition of HTTPS

The official definition of HTTPS is that it is used for the secure exchange of information between two end systems on a computer network, which is equivalent to adding a Secure security word on the basis of HTTP. In simple and popular terms, HTTPS is a convention and specification for the secure transmission of text, pictures, audio, video and other hypertext data between two points in the computer world. We can think of HTTPS as an extension of the HTTP protocol, but it does not guarantee the security of the transmission, so the question is, who will ensure the security? In HTTPS, communication protocols are encrypted using transport layer security or secure sockets layer. The relationship between them can be well understood with a mathematical formula: HTTP + SSL (TLS) = HTTPS.

2. The function of HTTPS

We all know that HTTPS is an extension of the HTTP protocol, which solves some problems that HTTP cannot solve. Let's first take a look at HTTP. Because HTTP is naturally plaintext transmission, anyone may intercept, modify or forge requests to send during the transmission of HTTP, which leads to the insecurity of HTTP. For example, there is no user authentication in the transmission process of HTTP, and the receiver and sender will not verify the integrity of the message, which is the result of HTTPS application. Therefore, we can say that the greatest role of HTTPS is to solve the security problem.

3. The working principle of HTTPS

There are three key indicators of how HTTPS works, namely, encryption, data consistency and authentication. Specifically, encryption means that HTTPS encrypts the data to protect it from eavesdroppers, which means that when a user is browsing a website, no one can monitor the exchange of information between him and the site, or track the user's activities, access records, etc., so as to steal user information. Data consistency means that the data will not be modified by the eavesdropper in the process of transmission, and the data sent by the user will be completely transmitted to the server to ensure that what the user sends is what the server receives. Identity authentication refers to confirming the other person's true identity, that is, proving that you are you, just like face recognition, it can prevent man-in-the-middle attacks and build user trust. Because of the guarantee of the above three key indicators, users can safely exchange information with the server.

Through a comprehensive analysis of the definition, function and principle of HTTPS, we can guide that although HTTPS is similar to HTTP in syntax and semantics, because SSL/TLS solves the problem of information security, we say that HTTPS will become a major development trend in the future.

That's how HTTPS works. What are the details of the function? do you have anything to gain after reading it? If you want to know more, welcome to the industry information!
