I am trying to get XML-RPC for PHP running under Mac OS X and SUSE Linux (on the host server). I have it working okay on http, but I can't get https going I am using setCertificate("/path_to_cert/server.crt", ""), but it doesn't seem to work with the Thawte Cert I have at home. This may be because it is not a pem-encoded cert. Any ideas how I can get this going
