Now the network has been widely used in people's daily life, so the network is also constantly upgrading, its security performance should be better and better in order to meet the requirements of people. Some of the compiled programs are easy to learn, easy to master, and easy for people to use. There was HTTPS as early as 16 or 17 years ago, and various browsers have added HTTPS certificates in order to increase their security performance. Today, let's talk about HTTPS certificates. The process of HTTPS certificate verification is actually very simple. Understand now, it is also convenient to use it in the future.

I. HTTPS certificate verification

The Internet generally uses some data, code, and some special words, which are not easy to understand. As we are now going to talk about the HTTPS certificate verification process, the network language interpretation is very official, and it would be easy for us to understand it in another way. It is like comparing the root CA institution to a company. The root certificate is the company's identity certificate, which is comparable to a person's ID card. The company will be issued certificates for different purposes by the intermediate CA institution above it. The intermediate CA organization is composed of different departments, and different departments issue different certificates. One of them specializes in issuing SSL certificates. This SSL certificate plus the root certificate and the intermediate certificate forms the certificate path. In HTTPS certificate verification, the browser verifies all the certificates in the certificate path one by one, and only all certificates can be trusted, the whole verification will not show errors. Then the root certificate is a key to verification, if the root certificate can not be granted, the rest will not be granted. If it is not granted, there are often three reasons, that is, the SSL certificate may not be issued by a trusted CA authority, the certificate may expire, and the domain name of the website visited may be different from that bound to the certificate. If there is one of the above reasons, it will cause the validation to fail. So it is necessary to have a good understanding of the details of the HTTPS certificate verification process.

Free download of SSL certificate

Nowadays, network users pay more and more attention to the information security of the website, and the SSL certificate is more and more known by people. A really authoritative good SSL certificate is not cheap, so there is a personal certificate, which is the kind of free SSL certificate. Can free SSL certificate download be reliable? This is obvious, certainly not as good as a good certificate, but each has its own value. This kind of free certificate can be used as long as it is not used in financial management such as payment and transfer.

In fact, adding a SSL certificate to the website is not complicated at all, as long as you go to a formal institution to buy it, but the price of the SSL certificate is not cheap, giving lawbreakers a chance to exploit loopholes, so users must be careful when doing HTTPS certificate verification.

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.
