General CSR Creation Guidelines

Before you can order an SSL certificate, you must first generate a Certificate Signing Request (CSR) for your server.

A CSR is an encoded file that provides you with a standardized way to send DigiCert your public key as well as some information that identifies your company and domain name. When you generate a CSR, most server software asks for the following information: common name (e.g., www.example.com), organization name and location (country, state/province, city/town), key type (typically RSA), and key size (2048-bit minimum).

If you aren't sure of the exact company name or location when you generate the CSR, don't worry; we can change and finalize that information during our review process before we issue the certificate.

Common Platforms & Operating Systems

NOTE: To remain secure, certificates must use keys that are at least 2048-bits in length. If your server platform can't generate a CSR
with a 2048-bit key, please contact us. See this article for more information.

Information Needed for a CSR

The Country is a two-digit code. For the United States, it's US. For countries outside of the United States, see this list of
SSL Certificate Country Codes.

State and Locality are the full names, e.g., California and Los Angeles.

The Organization name is your full legal company or personal name, as legally registered in your locality.

The Organizational Unit is whichever branch of your company is ordering the certificate, such as accounting, marketing, etc.

The Common Name is the Fully Qualified Domain Name (FQDN) for which you are requesting the SSL Certificate.

NOTE: If you are generating a CSR for a Wildcard SSL Certificate, your common name must start with an * (e.g., *.example.com). The Wildcard character (*) will be able to assume any name that does not have a dot character in it.

Once your CSR is created, you will copy and paste it into the online order form when you go to purchase your SSL certificate.
