A CA is a trusted third party that issues digital certificates for use with encrypted digitaltransactions. The digital certificate guarantees the identity of the Web site of the company that holds thecertificate. In this case, the PXGX UPS Card functions as both the CA and the certificate holder.You can use the card without installing its root CA (using HTTP), but the transactions will not be as secure aswith the root CA (using HTTPS). You can require secure transactions by configuring the card for HTTPS (see“Configuring HTTP and HTTPS” on page 28).
