(PHP ActiveX) POP3 Verify Signed (S/MIME) EmailDemonstrates how to download and verify digitally signed S/MIME email.
<?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.MailMan') $mailman = new COM("Chilkat.MailMan"); // Set the POP3 server's hostname $mailman->MailHost = 'pop.someMailServer.com'; // Set the POP3 login/password. $mailman->PopUsername = 'myLogin'; $mailman->PopPassword = 'myPassword'; // sa is a Chilkat.StringArray $sa = $mailman->GetUidls(); if ($mailman->LastMethodSuccess == 0) { print $mailman->LastErrorText . "\n"; exit; } $i = 0; while ($i < $sa->Count) { $uidl = $sa->getString($i); // email is a Chilkat.Email $email = $mailman->FetchEmail($uidl); if ($mailman->LastMethodSuccess == 0) { print $mailman->LastErrorText . "\n"; exit; } print $email->From . "\n"; print $email->Subject . "\n"; // The security layers of signed and/or encrypted emails // are automatically "unwrapped" when loaded into // a Chilkat email object. // An application only needs to check to see if an email // was received signed or encrypted, and then examine // the success/failure. For example: if ($email->ReceivedSigned == 1) { print 'This email was signed.' . "\n"; // Check to see if the signatures were verified. if ($email->SignaturesValid == 1) { print 'Digital signature(s) verified.' . "\n"; print 'Signer: ' . $email->SignedBy . "\n"; // The certificate used for signing may be obtained // by calling email.GetSignedByCert. // cert is a Chilkat.Cert $cert = $email->GetSignedByCert(); if ($email->LastMethodSuccess == 0) { print 'Failed to get signing certificate object.' . "\n"; } else { print 'Signing cert: ' . $cert->SubjectCN . "\n"; } } else { print 'Digital signature verification failed.' . "\n"; } } $i = $i + 1; } $mailman->Pop3EndSession(); ?> |
