I'm not sure about how you want to use the SSL certificate; assuming that what is desired is to install an SSL certificate on the WebServer, a couple of indications.
The process is way easier if your QlikView WebServer is deployed integrated on an IIS. Creating a self signed certificate with IIS is very straightforward (link is for IIS 7)
After creating the certificate you have two scenarios:
- If IIS is present, there is no configuration to be done in QlikView. Just import the certificate on IIS for the application pool in which the QlikView Webserver is deployed.
- If there's no IIS the process is pretty much the same but include some manual tasks.
On this second scenario I believe you'll find very useful the information shared by clint about how to enable SSL communication with QlikView WebServer without IIS:
The process for making the rest of the services communicate using certificates is more or less the same as the one described by Clint on the WebServer.
