// 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");

// Note: Requires Chilkat v9.5.0.77 or greater.

// Load the certificate on the smartcard currently in the reader (or on the USB token).
// Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
// See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
