For people, it is very convenient to transmit information through the Internet. When information is transmitted, people can communicate conveniently and quickly. Of course, network information also needs some security when it is transmitted so that users can rest assured to use it. Therefore, many enterprise websites begin to install ssl certificates. When installing ssl certificates for websites, what you need to be clear is There are many types of ssl certificates, so let's take a look at the types of ssl certificates and what's the difference.

What are the types of ssl certificates?

Ssl certificates are distinguished according to the number of domain names of certificates. Ssl certificates are divided into ssl single domain name certificate, multi-domain name ssl certificate and wildcard ssl certificate. According to certificate security, ssl certificate is divided into three types: dv ssl certificate, ov ssl certificate and ev ssl certificate.

What is the difference in the number of ssl certificate domain names?

A single domain name certificate protects a single domain name, which protects only one domain name, while a multi-domain name certificate can provide multiple domain name addresses with high flexibility, generally capable of protecting about 2-200 domain names. Wildcard domain name certificate is also known as pan-domain name certificate. It contains a large number of sub-domain names, which can meet the needs of most websites.

The number of domain names of ssl certificates is different, which means that the number of domain names protected by them is different, and the number of domain names of different types of websites is also different, so when selecting certificates, you need to combine the number of domain names of your own websites to choose.

What is the difference between the security levels of ssl certificates?

The different security level of ssl certificate has a great impact. Dv ssl certificate is a basic certificate, which is generally suitable for small websites or personal websites, while ov ssl certificate is also called enterprise digital certificate. Most enterprises can use ov ssl certificate to ensure the security of their websites. The security level of ev ssl certificate is relatively high, and it is also the highest security level of ssl certificate at present. It can be used for financial type websites as well as special types of websites.

When selecting a ssl certificate, we should pay attention to the number of domain names of the certificate and the security level of the certificate, because it affects the price of the certificate and whether the certificate is suitable for the website. Only by selecting the ssl certificate that meets the needs of the website can the security of the website be guaranteed.
