  • File name containing the certification authority’s response – browse the file system to find the certificate file.
  • Friendly name – this field helps the server administrator to easily locate a particular certificate. For example, a domain name of the certificate can be specified in this field.
  • Select a certificate store for the new certificate – the default value Personal should be kept.
