Certificate Signing Request (CSR)

A CSR is a file containing your SSL certificate application information, including your Public Key. Generate your CSR and then copy and paste the CSR file into the request webform.

When you generate your CSR, you must specify the following fields or your CSR will be rejected.

  • Country Name: US
  • State or Province Name: Texas
  • Locality Name (City): College Station
  • Organization Name: Texas A&M University
  • Organizational Unit Name: [Your department name]
  • Common Name: [Full host name - www.tamu.edu]

For help with generating a CSR, consult the Comodo Knowledge Base for your web-server type.

The CSR must be created from a 2048-bit or larger RSA key pair, or an ECC key pair.

Subject Alternative Name (SAN) certificates

  • For UCC or Multi-Domain SAN certificates the CSR you generate only needs to be for the single Common Name domain, aka the Primary Domain Name. Additional domains that you may require in the Subject Alternative Name will be added at the time of provisioning the certificate. Although the additional domains are not required to be included in the CSR, they should always be listed in the request.
  • While having the SAN field defined in the CSR is not a requirement, this can be submitted if desired.
