(Objective-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.

CkoImap *imap = [[CkoImap alloc] init];

// To use a secure SSL connection, set SSL and the port:
imap.Ssl = YES;
// The typical port for IMAP SSL is 993
imap.Port = [NSNumber numberWithInt: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.)
CkoCertStore *certStore = [[CkoCertStore alloc] init];
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
BOOL success = [certStore LoadPfxFile: @"myCertWithPrivateKey.pfx" password: @"secret"];
if (success != YES) {
    NSLog(@"%@",certStore.LastErrorText);
    return;
}

// Find the certificate by the subject common name:
CkoCert *cert = 0;
cert = [certStore FindCertBySubjectCN: @"Chilkat Software, Inc."];
if (certStore.LastMethodSuccess == NO) {
    NSLog(@"%@",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:
CkoCert *cert2 = [[CkoCert alloc] init];
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
success = [cert2 LoadPfxFile: @"myClientCert.pfx" password: @"secret"];
if (success != YES) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// Use the cert:
success = [imap SetSslClientCert: cert];

// Connect to an IMAP server.
success = [imap Connect: @"imap.someMailServer.com"];
if (success != YES) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Login
success = [imap Login: @"myLogin" password: @"myPassword"];
if (success != YES) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = [imap SelectMailbox: @"Inbox"];
if (success != YES) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

CkoMessageSet *messageSet = 0;
// We can choose to fetch UIDs or sequence numbers.
BOOL fetchUids = YES;
// Get the message IDs of all the emails in the mailbox
messageSet = [imap Search: @"ALL" bUid: fetchUids];
if (imap.LastMethodSuccess == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Fetch the emails into a bundle object:
CkoEmailBundle *bundle = 0;
bundle = [imap FetchBundle: messageSet];
if (imap.LastMethodSuccess == NO) {

    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Loop over the bundle and display the FROM and SUBJECT of each.
int i = 0;
int numEmails = [bundle.MessageCount intValue];
while (i < numEmails) {
    CkoEmail *email = [bundle GetEmail: [NSNumber numberWithInt: i]];
    NSLog(@"%@",email.From);
    NSLog(@"%@",email.Subject);
    NSLog(@"%@",@"--");

    i = i + 1;
}

// Disconnect from the IMAP server.
success = [imap Disconnect];
