Windows – How to create self signed wildcard (*.example.com) certificate

certificateiissslwindows

I'm trying to install Dynamics CRM 2011 RC and configure it for Internet Facing Deployment.

One of the requirements for this is a wildcard SSL certificate. Since I'm installing development/testing server, I don't have a budget for real certificate. So…

What is the easiest way to create Self Signed Wildcard SSL Certificate in Windows?

There isn't an EASY way, but the two that come to mind are:

First, For a web certificate, download the IIS6 Resource Kit tools, and use the SelfSSL.exe tool, choose *.example.com as the name and it will install to the certification database. You should be able to pull out the public/private key and use it however you want.

Second, is a much much harder way, Download the latest version of OpenSSL, and you should be able to generate it through that - I have only ever used it for an entire CA setup and never for a single certificate.

I found instructions for Linux, and it should be similar for Windows. Link here, with a few modifications. If you want help with what is needed for a full CA and/or can't find what you need, let me know and I'll try to find it out for you.
