Well, now that I see there are a few people on the list who are
knowledgeable about CACs, I'll be more specific about what I'm doing. We
already use CACs here at work, and some people need them to be able to
access some of the government web sites we use.

The problem is that some people here want to be able to automate/script
downloads from sites that require CAC cards for access. So I need to do
some kind of scripting to allow the command-line client cURL to be able
to use CAC card certificates, and specifically on the Mac OSX platform.

My working approach is to use the Mac OSX keychain utility, which is (as
far as I can tell) where the certificates are stored temporarily while
they are being used by the (Safari) web-browser to access the
CAC-enabled web site. I'm hoping I can just pull the certificates out of
keychain via the "security" utility, and feed them straight into cURL.
