(PHP ActiveX) DKIM Signature using Windows Current User Certificate StoreThis is a Windows-specific example to load a certificate from the Current User (registry-based) certificate store, and then use the certificate's associated private key for a DKIM signature.
<?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.Cert') $cert = new COM("Chilkat.Cert"); // The LoadByCommonName method searches the Windows Local Machine and Current User // registry-based certificate stores for a certificate having the common name specified. // If found, the certificate is loaded and ready for use. $success = $cert->LoadByCommonName('My Certificate ABC'); if ($success != 1) { print $cert->LastErrorText . "\n"; exit; } // The certificate must have an associated private key installed, and it must be a // private key that has been marked "exportable" when it was originally installed. if (!$cert->HasPrivateKey()) { print 'This certificate does not have a private key available.' . "\n"; exit; } // privKey is a Chilkat.PrivateKey $privKey = $cert->ExportPrivateKey(); if ($cert->LastMethodSuccess == 0) { print $cert->LastErrorText . "\n"; exit; } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Dkim') $dkim = new COM("Chilkat.Dkim"); // Load the private key into the DKIM object: $success = $dkim->LoadDkimPk($privKey->getPkcs8Pem(),''); if ($success != 1) { print $dkim->LastErrorText . "\n"; exit; } // The private key has been loaded into the DKIM object. See the other DKIM // examples for guidance on how to create a DKIM signature... ?> |
