(Swift 2) 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.

    let imap = CkoImap()

    // 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.)
    let certStore = CkoCertStore()
    // The 1st argument is the filename, the 2nd arg is the 
    // PFX file's password:
    var success: Bool = certStore.LoadPfxFile("myCertWithPrivateKey.pfx", password: "secret")
    if success != true {
        print("\(certStore.LastErrorText)")
        return
    }

    // Find the certificate by the subject common name:
    var cert: CkoCert?
    cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.")
    if certStore.LastMethodSuccess == false {
        print("\(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:
    let cert2 = CkoCert()
    // The 1st argument is the filename, the 2nd arg is the 
    // PFX file's password:
    success = cert2.LoadPfxFile("myClientCert.pfx", password: "secret")
    if success != true {
        print("\(cert!.LastErrorText)")
        return
    }

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

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

    // Login
    success = imap.Login("myLogin", password: "myPassword")
    if success != true {
        print("\(imap.LastErrorText)")
        return
    }

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

    var messageSet: CkoMessageSet?
    // We can choose to fetch UIDs or sequence numbers.
    var fetchUids: Bool = true
    // Get the message IDs of all the emails in the mailbox
    messageSet = imap.Search("ALL", bUid: fetchUids)
    if imap.LastMethodSuccess == false {
        print("\(imap.LastErrorText)")
        return
    }

    // Fetch the emails into a bundle object:
    var bundle: CkoEmailBundle?
    bundle = imap.FetchBundle(messageSet)
    if imap.LastMethodSuccess == false {
        messageSet = nil
        print("\(imap.LastErrorText)")
        return
    }

    // Loop over the bundle and display the FROM and SUBJECT of each.
    var i: Int = 0
    var numEmails: Int = bundle!.MessageCount.intValue
    while i < numEmails {
        var email: CkoEmail? = bundle!.GetEmail(i)
        print("\(email!.From)")
        print("\(email!.Subject)")
        print("--")
        email = nil
        i = i + 1
    }

    // Disconnect from the IMAP server.
