Today, the editor shared with you about the principle of https analysis, many people do not understand, today, in order to let you better understand the principle of https, so give you a summary of the following content, let's look down. I'm sure you'll get something.

Many people do not know this https principle, mainly because this thing is a bit abstract. So we can't figure out this https principle at first, but as long as we think about it carefully and comprehend it, we can easily know it. Let's take a closer look at this https principle.

Speaking of https principle is the role of this https protocol. This protocol is for data exchange with the server where the site is located. If there is some ordinary https certificate acquisition, this point is also necessary to know. This https is a website for confidentiality, not to be invaded by a third party into its own website in order to steal privacy. This is actually a kind of digital certificate, which can be used after being certified by CA certification authority. The authentication of this https protocol is definitely needed, because the authentication of digital certificates is the most critical step in online transactions. For example, this https certificate is to be certified, and the current electronic certification service organization must comply with the provisions of the Electronic signature Law and must pass the "Electronic Certification Service license" of the Ministry of Information Industry before it can operate legally.

We can know the relationship between the public key and the key. We assume that the asymmetric public key FK.pub can be safely released to the client, then our client only needs to encrypt the DK with FK.pub to send it to the server, and the server uses the asymmetric private key FK.pri to decrypt it, so that both the server and the client can get the DK. The process of encrypted communication based on DK known only to the client and server is secure. This is the general explanation of https principle.

These are the details of the principle analysis of https. Do you have anything to gain after reading it? If you want to know more about it, welcome to the industry information!
