(PHP Extension) Using Client Certificate w/ IMAP SSL

Demonstrates how to use a client-side certificate with an IMAP SSL connection. The SetSslClientCert method is called to specify a certificate to be used for the SSL connection.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?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 assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$imap = new CkImap();

// To use a secure SSL connection, set SSL and the port:
$imap->put_Ssl(true);
// The typical port for IMAP SSL is 993
$imap->put_Port(993);

// Load a certificate from a PFX file and use it.
// Note: Other methods are available to load pre-installed
// certificates from registry-based certificate stores.

// Create an instance of a certificate store object, load a PFX file,
// locate the certificate we need, and use it for signing.
// (a PFX file may contain more than one certificate.)
$certStore = new CkCertStore();
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
$success = $certStore->LoadPfxFile('myCertWithPrivateKey.pfx','secret');
if ($success != true) {
    print $certStore->lastErrorText() . "\n";
    exit;
}

// Find the certificate by the subject common name:

// cert is a CkCert
$cert = $certStore->FindCertBySubjectCN('Chilkat Software, Inc.');
if ($certStore->get_LastMethodSuccess() == false) {
    print $certStore->lastErrorText() . "\n";
    exit;
}

// If a PFX file is known to contain a single certificate,
// you may load it directly into a Chilkat certificate object.
// This snippet of source code shows how:
$cert2 = new CkCert();
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
$success = $cert2->LoadPfxFile('myClientCert.pfx','secret');
if ($success != true) {
    print $cert->lastErrorText() . "\n";
    exit;
}

// Use the cert:
$success = $imap->SetSslClientCert($cert);

// Connect to an IMAP server.
$success = $imap->Connect('imap.someMailServer.com');
if ($success != true) {
    print $imap->lastErrorText() . "\n";
    exit;
}

// Login
$success = $imap->Login('myLogin','myPassword');
if ($success != true) {
    print $imap->lastErrorText() . "\n";
    exit;
}

// Select an IMAP mailbox
$success = $imap->SelectMailbox('Inbox');
if ($success != true) {
    print $imap->lastErrorText() . "\n";
    exit;
}

// We can choose to fetch UIDs or sequence numbers.
$fetchUids = true;
// Get the message IDs of all the emails in the mailbox
// messageSet is a CkMessageSet
$messageSet = $imap->Search('ALL',$fetchUids);
if ($imap->get_LastMethodSuccess() == false) {
    print $imap->lastErrorText() . "\n";
    exit;
}

// Fetch the emails into a bundle object:

// bundle is a CkEmailBundle
$bundle = $imap->FetchBundle($messageSet);
if ($imap->get_LastMethodSuccess() == false) {

    print $imap->lastErrorText() . "\n";
    exit;
}

// Loop over the bundle and display the FROM and SUBJECT of each.
$i = 0;
$numEmails = $bundle->get_MessageCount();
while ($i < $numEmails) {
    // email is a CkEmail
    $email = $bundle->GetEmail($i);
    print $email->from() . "\n";
    print $email->subject() . "\n";
    print '--' . "\n";

    $i = $i + 1;
}

// Disconnect from the IMAP server.
$success = $imap->Disconnect();
