Is there any specific module available to configure a central certificate store in a windows 2012 server using DSC?
Can I use WindowsFeature resource to do this? After configuring the CCS , how should I proceed to add wildcard certificates for applications using DSC?
Well, you should be able to use the WindowsFeature resource to install it (the feature name is 'Web-CertProvider'). Configuring it probably needs a new resource, which would wrap around the WebAdministration module's *-WebCentralCertProvider* cmdlets. The certificates themselves are just PFX files on a shared drive, so you could potentially manage some of that with the built-in File resource.
