LWP and Digitial Certificates

Hi-
I was wondering if there is a way to automate retrieval of data from pages
that require a digital certificate. (I have the certificate on my computer
to access the pages, but am not sure how to create a perl program to get
past this certificate). Or, I was wondering if there might be a way to get
past the digital certificate and then have the perl program take over. Any
advice that can be given on this matter is greatly appreciated. Thanks.
