This Powershell script will import and bind a certificate to the Default Web Site. I use this script for Citrix StoreFront and Director deployments, but it’s written to be very flexible and versatile so can be used for other tasks.
The original idea came from scripts written by Thomas Albaek and Jerome Quief for Citrix StoreFront.
The way I’ve written this script it will actually remove any existing certificate bindings first, which is really handy for pushing out updated certificates as I found that other scripts written to do this task would fail when run more than once.
