// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$cert = new CkCert();

// If you know the smart card PIN, set it prior to loading from the smartcard/USB token.
$cert->put_SmartCardPin('12345678');

// Pass an empty string to allow Chilkat to discover the smart card or USB token automatically.
