Most IT departments have their own methods of producing
certificates.
Certificate/Key file location.
The viewLinc certificates are
located in the following folder:
\config\keys\viewlinc.key
\config\keys\viewlinc.crt
These files should be left as they are. They may be replaced
during upgrades. Please do not replace them with similarly
named files. The names of the files that viewLinc will laod are
located in the viewlinc.cfg configuration file:
\config\viewlinc.cfg
[web]
privatekeyfile = viewlinc.key
certificatefile = viewlinc.crt
When you have created your own files, the entries in
viewlinc.cfg must be modified to suit.

This file contains the certificate request details, and as such
is not required by viewLinc. It is an intermediate step.
Create a configuration file called SSLConfig.txt containing
your certificate details. E.G.:
[ req ]
distinguished_name= req_distinguished_name
