The CSR must contain the following mandatory encrypted information: your Country, State, City/Town, Name of the company, Department from your company, and the Domain name or IP address that you want the SSL Certificate to be issued for.
It may also contain this optional information: the email address where your CSR code and the Private Key will be sent to once they are both generated.
To avoid any errors, please make sure that:
- You DO NOT enter “http://” or “https://” along with your domain name as a common name when generating the CSR. Please enter only “www.domain.com” or “domain.com” as a common name. Also, make sure you don’t have any extra spaces before or after your domain name.
- When generating the CSR code you were given a CSR code and a Private Key. Make sure that you only enter the CSR code in the SSL Configuration form. DO NOT enter the Private Key, but save it and keep it in a safe location on your computer or email, because you will need it when installing the SSL Certificate on your website/server.
- The CSR that you enter in the SSL Configuration form should include the following two lines: “—–BEGIN CERTIFICATE REQUEST—–” header and “—–END CERTIFICATE REQUEST—–” footer.
- For Wildcard SSL Certificates – When generating the CSR code for a Wildcard SSL Certificate, you have to include an asterisk and dot (*.) before your domain name. In other words, you should fill in *.yourdomain.com as a common name in your CSR.
- For Multi-Domain Wildcard SSL Certificates – Any Multi-Domain Wildcard SSL Certificate should start with a non-Wildcard domain. This means that you need to generate the CSR for a single domain – example.com – without any asterisk sign “*.”. Please read more in this FAQ.
- For IP Address SSL Certificates – For Comodo InstantSSL Premium, the common name should be your IP address. For GoGetSSL Public IP SAN SSL Certificate, you will be asked to generate a CSR with NO Common Name. Here is how to do it.
