(PHP Extension) Create CAdES-BES .p7m using Smart Card or USB TokenDemonstrates how to create a CAdES BES invoice.xml.p7m using a certificate stored on a smart card or USB token. Note: This example requires Chilkat v9.5.0.77 and at the time of this writing is restricted to the Windows operating system.
<?php // 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. // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $crypt = new CkCrypt2(); // Use a certificate on a smartcard or USB token. $cert = new CkCert(); // 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. $success = $cert->LoadFromSmartcard(''); if ($success != true) { print $cert->lastErrorText() . "\n"; exit; } // Provide the smartcard PIN. // If the PIN is not explicitly provided here, the Windows OS should // display a dialog for the PIN. $cert->put_SmartCardPin('000000'); // Provide the certificate for signing. $success = $crypt->SetSigningCert($cert); if ($success != true) { print $crypt->lastErrorText() .
