SSL digital certificate is a digital certificate that can protect the security of transmission data and verify the identity of the server, there are many kinds of SSL certificates, and wildcard certificates are one of the special types. With the development of the Internet, the number of wildcard SSL certificates issued is also increasing, in order to enable users to choose the wildcard SSL certificate that meets their needs, today with the SSL shield to understand the DV wildcard SSL certificate and the OV wildcard SSL certificate.
1.Both DV wildcard SSL certificates and OV wildcard SSL certificates can protect the primary domain name and all subdomains under the primary domain name at the same time, and the wildcard SSL certificate can provide encryption and security protection for subdomain sites under an unlimited number of consented domains at the same time, without the need to apply for a separate certificate for each subdomain.
2.The verification method is different: when applying for a DV wildcard SSL certificate, you only need to verify the ownership of the domain name, and the CA certification authority will issue the certificate if the verification is successful, because the validity of the domain name of the detachment is verified, and the security is relatively low. However, the application process for an OV wildcard SSL certificate is too expensive and complicated, and it not only verifies the ownership of the domain name, but also verifies the authenticity of the application subject, so as to ensure that the application subject has a legal identity and is relatively secure.
3.Different: There are also differences in the cost of the flight when the DV wildcard SSL certificate and the OV wildcard SSL certificate are verified. The ** of the DV wildcard SSL certificate is relatively low, so it is more suitable for some small ** or personal **. For example, Certum's DV wildcard SSL certificate, which is only 700 yuan, can convert HTTP plaintext transmission to HTTPS encrypted transmission after being deployed to improve security. The OV wildcard SSL certificate has a higher pair, which is more suitable for some large enterprises or organizations with high security requirements. For example, Certum's OV wildcard SSL certificate, ** is 1,390 yuan, installed on ** can not only improve SEO ranking, but also directly find the application subject information in the certificate information, so as to enhance the user's trust in **.
