How do I generate my own security certificate?

I want to create a security certificate I can use for https connectivity.  I only want it for my own use and I don't want to buy one -- is there a free way to create one (since it's for my own use I don't care if it's not signed by a CA).

You do this in Windows by using Certificate Services, which is installed through Add/Remove Windows Components.  Once CS is installed (the issuing server becomes the CA, btw), you can review the following for instructions on how to issue and install the cert:

I assume to do that you need Windows server (I want to host the certificate on my host provider not my own computer)?  Is there any way to do it using Windows XP (and not server)?

Right, you need a server version.  Windows XP and Win2k come with a rudimentary version of IIS, but not Certificate Services.  If you don't have a server version, you may have to choose between upgrading and buying an inexpensive cert, ie. GoDaddy - $29.99/yr (, Ultra SSL - $29/yr (
