We can not live without the network, and there are more and more requirements for the speed of the network. Especially for network security, people always prefer those websites with high security performance, such as those with complete certificates. Speaking of certificates, you will think of self-built certificates. Today, we will mainly introduce the relevant self-built certificates. So, what is the https self-built certificates?

In fact, https self-built certificate and self-signed certificate are exactly the same, which may be relatively high-end for us, but it is very simple for experts to do it. In fact, it is not very complicated, and the production principle of https self-built certificate is not very complicated, which is a process of connection between the website and the browser. First of all, the browser initiates a request for a certificate to the server, and after the server receives the request, it needs to provide a digital certificate, which is obtained through the verification of the client. After that, it is to verify whether there is any problem with the information of the certificate, such as the issuing authority and the time.

First, how to establish https certificate

The first step is to make a CSR file. Maybe you don't know much about this. In fact, CSR is a Certificate Secure Request certificate request document made by the applicant. How to establish a https certificate? In the process of making a certificate, there will be two keys, one is the CSR file, and the other is the private key, which will be stored directly on the server. The generation of CSR files is also relatively complex, need to refer to WEB SERVER documents, general APACHE and so on. The second is CA authentication. To put it simply, there are two types of authentication for submitting CSR to CA,CA. One is domain name authentication. The speed of authentication is very fast. You only need to send it to the administrator's mailbox, but the certificate issued does not have the administrator's name. Another is to use the enterprise's phone for authentication, in which the dv certificate only verifies the ownership of the domain name, and the above two items need to be verified at the same time to apply for the OV or EV ssl certificate.

2. What should be paid attention to in the https certificate of self-built dns

First of all, it must be clear that the https certificate of self-built dns does not need to master its principle, but if it is not in accordance with its principle, it will waste a lot of time. Before building a https local server, what do you need to pay attention to before building the https certificate of self-built dns? For example, make sure that the website can be connected to the external network, and can be configured with dns, otherwise it will be in vain.

After reading the above introduction, everyone should have a certain understanding of this! Generally speaking, the https self-built certificate is worth learning, which is of great help to the security of the network.

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.
