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.Imap imap = new Chilkat.Imap();

bool success;

//  Anything unlocks the component and begins a fully-functional 30-day trial.
success = imap.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(imap.LastErrorText);
    return;
}

//  To use a secure SSL connection, set SSL and the port:
imap.Ssl = true;
//  The typical port for IMAP SSL is 993
imap.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.)
Chilkat.CertStore certStore = new Chilkat.CertStore();
//  The 1st argument is the filename, the 2nd arg is the
//  PFX file's password:
success = certStore.LoadPfxFile("myCertWithPrivateKey.pfx","secret");
if (success != true) {
    MessageBox.Show(certStore.LastErrorText);
    return;
}

//  Find the certificate by the subject common name:
Chilkat.Cert cert = null;
cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.");
if (cert == null ) {
    MessageBox.Show(certStore.LastErrorText);
    return;
}

//  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:
Chilkat.Cert cert2 = new Chilkat.Cert();
//  The 1st argument is the filename, the 2nd arg is the
//  PFX file's password:
success = cert2.LoadPfxFile("tagtooga_secret.pfx","secret");
if (success != true) {
    MessageBox.Show(cert.LastErrorText);
    return;
}

//  Use the cert:
imap.SetSslClientCert(cert);

//  Connect to an IMAP server.
success = imap.Connect("mail.chilkatsoft.com");
if (success != true) {
    MessageBox.Show(imap.LastErrorText);
    return;
}

//  Login
success = imap.Login("myLogin","myPassword");
if (success != true) {
    MessageBox.Show(imap.LastErrorText);
    return;
}

//  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox");
if (success != true) {
    MessageBox.Show(imap.LastErrorText);
    return;
}

Chilkat.MessageSet messageSet = null;
//  We can choose to fetch UIDs or sequence numbers.
bool fetchUids;
fetchUids = true;
//  Get the message IDs of all the emails in the mailbox
messageSet = imap.Search("ALL",fetchUids);
if (messageSet == null ) {
    MessageBox.Show(imap.LastErrorText);
    return;
}

//  Fetch the emails into a bundle object:
Chilkat.EmailBundle bundle = null;
bundle = imap.FetchBundle(messageSet);
if (bundle == null ) {

    MessageBox.Show(imap.LastErrorText);
    return;
}

//  Loop over the bundle and display the FROM and SUBJECT of each.
int i;
for (i = 0; i <= bundle.MessageCount - 1; i++) {
    Chilkat.Email email = null;
    email = bundle.GetEmail(i);
    textBox1.Text += email.From + "\r\n";
    textBox1.Text += email.Subject + "\r\n";
    textBox1.Text += "--" + "\r\n";

}

//  Disconnect from the IMAP server.
imap.Disconnect();
