(PHP ActiveX) ScMinidriver - Delete Smart Card Key ContainerSee more ScMinidriver ExamplesDemonstrates how to delete the contents of a key container on a smart card (or USB token).
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Chilkat recommends the following free tool for interactively examining the contents of your smart card // through the ScMinidriver interface: MGTEK Tool for Minidriver enabled Smart Cards // Let's first look at our smart card.. // Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.ScMinidriver') $scmd = new COM("Chilkat.ScMinidriver"); // First we need to acquire a context to the smart card in the reader where it is inserted. // Reader names (smart card readers or USB tokens) can be discovered // via List Readers or Find Smart Cards $readerName = 'Alcor Micro 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"; // To delete the contents of a key container, we'll need to be PIN authenticated.. // For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example $pinId = 'user'; $retval = $scmd->PinAuthenticate($pinId,'0000'); if ($retval != 0) { print 'PIN Authentication failed.' . "\n"; $scmd->DeleteContext(); exit; } // Let's delete the contents of key container #7 // This deletes both keys (signature key and "key exchange" key) that might be present in the key container. // (It is not possible to delete just one or the other.) $success = $scmd->DeleteKeyContainer(7); if ($success == 0) { print $scmd->LastErrorText . "\n"; $scmd->DeleteContext(); exit; } $scmd->DeleteContext(); print 'Successfully delete the contents of key container #7' . "\n"; ?> |
