(PHP ActiveX) ScMinidriver - Get Public Keys from Smart Card Key ContainerSee more ScMinidriver ExamplesDemonstrates how to query a key container on a smart card (or USB token) to get the public part of the private keys that are present. A key container can hold two separate private keys -- one in the "signature" position, and the other in the "key exchange" position.
<?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 our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool: // 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"; // We likely shouldn't need to authenticate with the smart card (use a PIN) to simply get a public key, // so we can skip the PIN authenticatin step.. // Let's get the key(s) present in Container #7. // In our case (shown in the image above), there is a private key in the "key exchange" position, but no key in the "signature" position. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PublicKey') $pubkey_sig = new COM("Chilkat.PublicKey"); // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.PublicKey') $pubkey_kex = new COM("Chilkat.PublicKey"); $success = $scmd->GetContainerKeys(7,$pubkey_sig,$pubkey_kex); if ($success == 0) { print $scmd->LastErrorText . "\n"; exit; } if ($pubkey_sig->Empty == 1) { print 'No signature key is present.' . "\n"; } else { print 'Signature key:' . "\n"; print $pubkey_sig->getPem(1) . "\n"; } if ($pubkey_kex->Empty == 1) { print 'No Key Exchange key is present.' . "\n"; } else { print 'Key Exchange key:' . "\n"; print $pubkey_kex->getPem(1) . "\n"; } $scmd->DeleteContext(); print 'Success.' . "\n"; // Here's the output of the above sample code: // Card name: IDPrime MD T=0 // No signature key is present. // Key Exchange key: // -----BEGIN RSA PUBLIC KEY----- // MIIBCgKCAQEAsXeRhM55P13FbpNcXAMR3olbw2Wa6keZIHu5YTZYUBTlYWId+pNi // wUz3zFIEo+0IfYR0H27ybIycQO+1IIzJofUFNMAL3tZps2OKPlsjuCPls6kXpXhv // /gvhux8LrCtp4PcKWqJ6QVOZKChc7WAx40qFWzHi57ueqRTv3x0kESqGg/VjsqyT // Evb55psJO2RsfhLT7+YVh3hImRM3RDaJdkTkPuOxeFyT6N7VXD09329sLuS3QkUb // E9zEKDnz9X3d8dEQdJhSI9ba5fxl8R7fu8pB67ElfzFml96X1jLFtzy1pzOT5Fc4 // ROcaqlYckVzdBq9sxezm6MYmDBjNAcibRwIDAQAB // -----END RSA PUBLIC KEY----- ?> |
