Anyone have any information on this?
You can sign your own SSL certificate if it is what you mean. You can go here for some advice on setting a self-signed certificate under linux, alternatively you can go here for advices for IIS 6 based environments.
You can create as many SSL certificates as you want with OpenSSL for example.
If you don't care about proper trust-chain validation to a root Certificate Authority, you can use a self-signed cert.
MS has a makecert tool.
