This article mainly introduces what https certification refers to, the article is very detailed, has a certain reference value, interested friends must read it!

As we all know, if a general website wants to be safe, it needs to be authenticated by the website, that is, https authentication, and https certification is considered safe. Then what is https certification? let's take a look at it.

First of all, the so-called website authentication refers to the authentication and configuration of the https certificate issued by the CA organization, and the https certificate authentication is considered as the security of the website. Https is a very secure SSL certificate, and because it is issued by professional CA institutions, it is deeply loved by network users, but if https wants to be configured and used normally, it must be certified. What is the authentication principle of https? the client sends a client hello to the server, and the server returns a serverhello to the client. Since the discussion in this article is the encryption topic of https, we only discuss the encryption of information transmission.

And CA is relatively secure, because it adopts a unique encryption method, so it is very secure. And in the process of transmission, the client will not disclose. However, the content of CA is very complicated, so it can not be said clearly in a few words, it is very complicated. Therefore, if the operation of the website is only a simple operation, then the transmission process of information is not safe, because there are many ways to intercept it, so there are hidden dangers. The transmission between the two is transparent to the middleman, so the middleman can obtain any data between the two ends, and then forward the data to both sides intact, because the middleman also gets the three elements and the public key. It can still decrypt the transmission content, and can also tamper with the content.
