(PHP ActiveX) Download and Trust the DigiCert Global Root CADemonstrates how to download a root certificate and trust it. For more information, see https://www.digicert.com/digicert-root-certificates.htm
<?php // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // In this example, the URLs for the DigiCert root CA certs are available at this web page: // https://www.digicert.com/digicert-root-certificates.htm // This example downloads the "DigiCert Global Root G3" // Valid until: 15/Jan/2038 // Serial #: 05:55:56:BC:F2:5E:A4:35:35:C3:A4:0F:D5:AB:45:72 // Thumbprint: 7E04DE896A3E666D00E687D33FFAD93BE83D349E $certUrl = 'https://dl.cacerts.digicert.com/DigiCertGlobalRootG3.crt'; // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http') $http = new COM("Chilkat.Http"); // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $bdCert = new COM("Chilkat.BinData"); $success = $http->DownloadBd($certUrl,$bdCert); if ($success == 0) { print $http->LastErrorText .
