Differences Between Types of SSL Certificates

Updated Time:2022-03-08  Views:34257

This site's SSL certificate management service provides three types of SSL certificates: OV, EV, and DV.

This chapter will introduce the differences between the various types of certificates.


* Special enterprises do not support applying for OV and EV certificates. For example: the military, some special agencies of the government, state secret units, etc.

Reason: The unified social credit code publicity and query platform for organizations across the country cannot find the relevant information of special enterprises, and thus cannot complete the organizational identity verification. Therefore, special enterprises cannot use OV and EV type SSL certificates.
