(PHP Extension) Use a Custom Set of Trusted Root CertificatesDemonstrates how to build a set of trusted root certificates to be used globally by all Chilkat classes.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $trustedRoots = new CkTrustedRoots(); // Indicate that we will NOT trust any pre-installed certificates on the system. $trustedRoots->put_TrustSystemCaRoots(false); // Thawte is a certificate authority that provides a .zip download of their // root CA certificates: https://www.thawte.com/roots/index.html // The direct download link is: https://www.verisign.com/support/thawte-roots.zip // Note: The above URLs are valid at the time of writing this example (29-May-2015). // Assuming the .zip has already been downloaded, open it and load each .pem file into // our trusted roots object. $zip = new CkZip(); // Open a .zip containing PEM files, among other things.. $success = $zip->OpenZip('qa_data/certs/thawte-roots.zip'); if ($success != true) { print $zip->lastErrorText() . "\n"; exit; } // entry is a CkZipEntry $entry = $zip->FirstMatchingEntry('*.pem'); if ($zip->get_LastMethodSuccess() != true) { print 'No entries matched.' . "\n"; exit; } $cert = new CkCert(); $bHasMoreEntries = true; while (($bHasMoreEntries == true)) { print 'Entry: ' . $entry->fileName() . "\n"; // Get the PEM of the CA cert: $pemStr = $entry->unzipToString(0,'utf-8'); // Load it into a certificate object: $success = $cert->LoadPem($pemStr); if ($success != true) { print $cert->lastErrorText() . "\n"; } // Add it to the trusted roots. $trustedRoots->AddCert($cert); // The NextMatchingEntry method was added in v9.5.0.50 // nextEntry is a CkZipEntry $nextEntry = $entry->NextMatchingEntry('*.pem'); $bHasMoreEntries = $entry->get_LastMethodSuccess(); // entry is a CkZipEntry $entry = $nextEntry; } // Activate the trusted roots globally for all Chilkat objects. // This call really shouldn't fail, so we're not checking the return value. $success = $trustedRoots->Activate(); ?> |
