In order to use curl with secure sites you will need a ca-bundle.crt file; here's a PHP script I've written which creates a fresh ca-bundle:

http://www.gknw.net/php/phpscripts/mk-ca-bundle.php

I've also written scripts in other languages, f.e. the Perl one which ships now with curl distributions:

http://curl.haxx.se/lxr/source/lib/mk-ca-bundle.pl

and also a Win32 WSH script if you prefer that:

http://www.gknw.net/vb/scripts/mk-ca-bundle.vbs



HTH, Guenter.
