The certificate issuer will sign the request and send back the certificate. To generate a certificate request:

  1. Create the certificate request with command,
openssl req -new -key server.key -out server.csr

You will be asked for more information about your organization and web site. Please give correct information. You should give valid domain names of your web site when you are asked for Common Name but not any aliases. To determine the valid domain name, you can use commands such as nslookup, dig or host. For example, if the web site can be accessed via both and, usually is the valid domain name (canonical name), is an alias; should be used for the Common Name.
