One of the essential things about https certificates is the https protocol. Https certificate is now a trend, people use the network, set up websites and so on can not do without this https certificate, but the real need to pay attention to this https protocol. So what is the concept of this https protocol? What is one of the functions of this https protocol?

In the final analysis, this https is a secure communication channel. It has two ports, one is the receiver and the other is the sender. There is a certain risk in the exchange of information between these two points, so there is the emergence of this https protocol. To put it simply, it is the secure version of http, which uses ssl encrypted http protocol, and then the function of this channel is mainly realized by three things. The first is that there is a public key, which is open to everyone. The key is your own, which is unknown to others, and there is the encryption of a HSAH function. The method of transmitting information used by HTTP protocol is plaintext transmission, so there are great risks, such as eavesdropping, tampering and hijacking of information, but TLS/SSL has the functions of identity authentication, information encryption and integrity check, so this protocol can prevent this type of problems from happening.

In this way, we can see the effect of the https agreement. The first is that you can encrypt some data that you do not want others to know, mainly to prevent your personal information from being disclosed, and the second is to significantly speed up the loading speed of the page. this experience is very good, the third is to protect the identity of a security, mainly to prevent phishing sites, the fourth is that the data will not be maliciously tampered with in the process of transmission, to ensure the authenticity of this information. The above is an embodiment of the role of the https protocol.

SSL certificate securely encrypts the website, which can effectively prevent hijacking, prevent your website from being maliciously implanted with advertisements, prevent tampering and monitoring from leaking users' passwords, and optimize the SEO ranking of search engines with SSL certificates.
