Now many people want to buy expensive certificates, this involves the dv certificate, in fact, he also has a free dv certificate, many people do not trust the free DV certificate, and then I will tell you whether the free DV certificate can be used or not. At the same time, how to solve the failure of ssl? And the advantages and disadvantages of self-signed ssl certificate.

1. Free dv certificate

According to the editor's experience, free DV certificates can be used. Now many internationally certified certification authorities have free dv certificates. Although this kind of certificate is free, it can also play the role of encrypting data in the process of transmitting information, and it can also encrypt the data when users use the website in addition to encrypting the transmission information. You can see the name of the enterprise and the green logo for Internet security, so that users do not have to worry about some dangerous problems when browsing the website, but these free certificates are still different from the paid certificates. It would be better to choose some paid certificates when strength permits.

2. Ssl failed

When the ssl certificate fails, in order to solve this problem, we must first look at which cause caused the failure. The reasons for the failure are as follows: the time problem on the system, the validity period of the certificate and the security level of the browser, as well as the steps in the process of certificate configuration. If you encounter this problem, you can take a look at what caused the failure through these aspects. If you change the time, you can apply for a new certificate. If it expires, you need to apply for a new certificate. If the security level is too high, you can set it. If it is due to a step problem, you can reconfigure the certificate. I believe this problem can be solved.

3. Self-signed ssl certificate

For example, in order to save a certain amount of money, some enterprises will make their own self-signed ssl certificates. This kind of certificate will not authenticate other certificates when it is used. In general, if it is such a website, it will not give authentication to our installed and configured certificates, it will prompt invalidation, and this kind of certificate will not be certified by international institutions, so there will be a certain risk. In general, it is not recommended to use self-signed ssl certificates, like many well-known brands of ca institutions have free ssl certificates, we can use this kind of certificate will be relatively better.
