It’s seems to me that lot of developers still don’t know there is a very easy way to create a temp SSL for your local server for testing your web application.
You don’t have to obtain a trial SSL’s from third party venders or installing and using certificate service.
All you have to do is just use selfssl.exe which coming with IIS6 resource kit . Even though that resource kit is for IIS6 you can use it (selfssl.exe) with XP (IIS 5.1). I think it’s also compatible with Win2k also (IIS 5.0).
BTW Today I found this simple tutorial which describes nicely how to install IIS6 Resource kit and use selfssl.exe.
