Getting certifications to use with SSL connections

How can I having a site url obtain its certification in order to use it with some program I'm using that'll have to use it?

the page im talking about is: https://webpac.telepac.pt/detailTraffic/sapoADSL.html

I need the .CER file of that page, I tried viewing it using mozilla and it says which is it but it doesnt allow me to expert it to a .cer file..any suggestions? To acomplish what I need I have to really have the .CER file

Thanks in advance

.cer files are specific to the webserver - by design - so that you cannot pretend to be a server you're not ...

hmm? How do IE for example(or mozilla) connect using the certificates then? I'm confused

How is this VB Related?

Actually is not DIRECTLY vb related but here i'd get more exposure -_-;

You have to buy a certification for SSL. I think they run about $500.
