(.NET Core C#) 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.

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

Chilkat.Imap imap = new Chilkat.Imap();

// 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:
bool success = certStore.LoadPfxFile("myCertWithPrivateKey.pfx","secret");
if (success != true) {
    Debug.WriteLine(certStore.LastErrorText);
    return;
}

// Find the certificate by the subject common name:
Chilkat.Cert cert = null;
cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.");
if (certStore.LastMethodSuccess == false) {
    Debug.WriteLine(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("myClientCert.pfx","secret");
if (success != true) {
    Debug.WriteLine(cert.LastErrorText);
    return;
}

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

// Connect to an IMAP server.
success = imap.Connect("imap.someMailServer.com");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

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

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

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

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

    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Loop over the bundle and display the FROM and SUBJECT of each.
int i = 0;
int numEmails = bundle.MessageCount;
while (i < numEmails) {
    Chilkat.Email email = bundle.GetEmail(i);
    Debug.WriteLine(email.From);
    Debug.WriteLine(email.Subject);
    Debug.WriteLine("--");

    i = i + 1;
}

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