(PHP ActiveX) Create XML Digital Signature using Certificate on Smart CardSee more ScMinidriver ExamplesDemonstrates how to load a certificate located on a smart card or USB token and then use it for creating an XML digital signature such that the cryptographic signing happens on the smart card.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.ScMinidriver') $scmd = new COM("Chilkat.ScMinidriver"); // Reader names (smart card readers or USB tokens) can be discovered // via List Readers or Find Smart Cards $readerName = 'SCM Microsystems Inc. SCR33x USB Smart Card Reader 0'; $success = $scmd->AcquireContext($readerName); if ($success == 0) { print $scmd->LastErrorText . "\n"; exit; } // If successful, the name of the currently inserted smart card is available: print 'Card name: ' . $scmd->CardName . "\n"; // If desired, perform regular PIN authentication with the smartcard. // For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example $retval = $scmd->PinAuthenticate('user','000000'); if ($retval != 0) { print 'PIN Authentication failed.' . "\n"; } // You can find a cerficate using any of the following certificate parts: // "subjectDN" -- The full distinguished name of the cert. // "subjectDN_withTags" -- Same as above, but in a format that includes the subject part tags, such as the "CN=" in "CN=something" // "subjectCN" -- The common name part (CN) of the certificate's subject. // "serial" -- The certificate serial number. // "serial:issuerCN" -- The certificate serial number + the issuer's common name, delimited with a colon char. // These are the same certificate parts that can be retrieved by listing certificates on the smart card (or USB token). // See List Certificates on Smart Card Example $certPart = 'subjectCN'; $partValue = 'PIVKey E42D60A759D39147A26E0AF2FB1183C5'; // If the certificate is found, it is loaded into the cert object. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Cert') $cert = new COM("Chilkat.Cert"); $success = $scmd->FindCert($certPart,$partValue,$cert); if ($success == 0) { print 'Failed to find the certificate.' .
