Important: If you obtained a matching SSL key and certificate from a provider, a certificate signing request (CSR) is not required. Continue to Uploading an SSL certificate.
You can create a CSR file by using the System Administrator. A CSR file contains the fully qualified domain name (FQDN), organization name, location, public key, and other information required to create the SSL certificate. The CSR is submitted to a public certificate authority (CA), which that validates this information and issues the SSL certificate.
After the CA issues the SSL certificate in .crt or .pem format, upload the certificate and private key as described in Uploading an SSL certificate.
