SSL digital certificates can be divided into two categories, one can be divided into three types of SSL certificates according to verification methods: DV domain name verification SSL certificate, OV enterprise verification SSL certificate, EV extended verification SSL certificate; the other category can be divided into single domain name SSL certificate, multi-domain name SSL certificate and wildcard certificate according to the number of domain names. So what's the difference between the types of these SSL digital certificates?

1. Verification method class

DV SSL certificate (domain name verification): a SSL certificate that can be issued in a few minutes without the need to manually verify the real identity of the applicant. The price is generally between 100 yuan and 1000 yuan, which is suitable for individuals or small websites.

OV SSL certificate (enterprise verification): you need to verify the ownership of the domain name and the identity information of the enterprise to prove that the applicant is a legitimate and real entity, which is usually issued within 1 to 5 working days. The price is generally about 100 yuan to 1000 yuan, suitable for enterprise users to apply.

EV SSL certificate (extended verification): in addition to verifying domain name ownership and enterprise identity information, you also need to submit extended verification, such as Deng and Bradstreet. Usually, CA institutions will also make a return visit by phone, and usually issue a certificate within 2-7 working days. The price is generally about 1000 yuan to 10,000 yuan, which is suitable for online trading websites and enterprise websites.

The difference between DV, OV and EV SSL certificates:

The main difference between DV and OV certificate is that DV certificate does not contain enterprise name information, while OV certificate contains enterprise name information, and OV is more expensive than DV and has higher security level.

The main difference between OV and EV certificates is that browsers have more "trust" in EV certificates. When browsers access EV certificates, they can display the company name in the address bar and turn the address bar green.

Second, the number of domain names

Single domain name SSL certificate: protects only one domain name (including SSL certificate with www and without www). It can be a top-level domain name or a second-level domain name, such as anxinssl.com and www.anxinssl.com or bbs.anxinssl.com.

Multi-domain name SSL certificate: multiple domain names can be protected at the same time without restricting the type of domain names; for example, anxinssl.com and its subdomains, idcspy.com and its subdomains, abc.com and its subdomains, etc., up to 2200 domain names can be protected.

Wildcard certificate: only one domain name and all its lower-level domain names can be protected without limiting the number of domain names; for example, anxinssl.com and all its subdomains, there is no limit on the number of domain names.

The difference between single domain name, multi-domain name and wildcard SSL certificate is obvious. The only thing that is difficult to distinguish is multi-domain name SSL certificate and wildcard certificate. The difference between them is that multi-domain name SSL certificate can protect different main domains or subdomains. A certificate can protect up to 2100 domain names, which is suitable for users with many top-level domain names. The wildcard certificate can only protect one domain name and all lower-level domain names of that domain name. There is no limit on the number of domain names at the next level. It is suitable for users with a large number of sub-domains.

Third, how to choose the type of SSL digital certificate that suits you?

1) first consider the number of domain names you own. Select a single domain name SSL certificate for a single domain name, multiple domain name certificates for multiple primary domains, and wildcard certificates for multiple subdomains of the same domain name.

2) secondly, consider the verification method, if it is a human website blog, you can only choose the DV SSL certificate, because OV/EV needs to verify organizational information, individuals can not provide this information. For enterprise users, Anxin certificate recommends to choose OV and EV SSL certificate, which is more reliable, and EV SSL certificate can display the enterprise name in the browser address bar, which is conducive to the promotion of corporate brands and give users a sense of trust.
