Prior to purchasing an SSL Certificate, a Certificate Signing Request (CSR) needs to be generated for the server where the certificate will be installed.
A Microsoft IIS 6.0 or 7.0 server, or a Red Hat server, has a new Symantec SSL Assistant to assist in automatically generating a CSR and installing the certificate. As an independent subsidiary of Symantec, Thawte offers Symantec SSL Assistant as a benefit of their corporate relationship.
