// 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");

//  LoadFromFile will load virtually any certificate format file.
//  It will auto-recognize the format and load appropiately.
