Notice

Currently, paid certificates on the market (including Geotrust, Symantec, Digcert, Entrust, Comodo, etc.) basically support Chinese. If requesting for OV and EV certificates, it is recommended in Chinese, so that the company information will be displayed in Chinese. If for a DV certificate, English is OK.
Encryption Algorithm& Key Size:RSA algorithm and 2048-bit key size are the new international industry standard and enough to ensure security well without special need.
Domain Name:
- Please fill in “*.yourdomain.com” if website will be secured by a wildcard SSL certificate.
- Please input a domain name or a subdomain name for the single domain certificate.
- Only input a main domain name secured for a multi-domain SAN SSL certificate, and then enter the rest domain names when submitting the certificate.
In addition to generating a CSR, the web server will also export another file called a private key. Please save the two files used in the installation of SSL certificate. If the private key is lost or compromised, you need to regenerate the CSR and reissue your SSL Certificate.
