What is a CSR?

A CSR is an unsigned certificate for submission to a Certification Authority, which signs it with the Private Key of their CA Certificate. Once the CSR is signed, it becomes a real certificate.

Once your CSR is processed by InstantSSL, your SSL Certificate can be generated and supplied back to you.

When I generate a CSR what do I put in the Common Name field?

The Common Name field contains the domain or server name. Do not include http:// before the name or any subfolders indicated by the / after the domain name.
