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.

require 'chilkat'

imap = Chilkat::CkImap.new()

#  Anything unlocks the component and begins a fully-functional 30-day trial.
success = imap.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  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 = Chilkat::CkCertStore.new()
#  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
end

#  Find the certificate by the subject common name:

cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.")
if (cert == nil )
    print certStore.lastErrorText() + "\n"
    exit
end

#  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 = Chilkat::CkCert.new()
#  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)
    print cert.lastErrorText() + "\n"
    exit
end

#  Use the cert:
imap.SetSslClientCert(cert)

#  Connect to an IMAP server.
success = imap.Connect("mail.chilkatsoft.com")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Login
success = imap.Login("myLogin","myPassword")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  We can choose to fetch UIDs or sequence numbers.
fetchUids = true
#  Get the message IDs of all the emails in the mailbox
messageSet = imap.Search("ALL",fetchUids)
if (messageSet == nil )
    print imap.lastErrorText() + "\n"
    exit
end

#  Fetch the emails into a bundle object:

bundle = imap.FetchBundle(messageSet)
if (bundle == nil )

    print imap.lastErrorText() + "\n"
    exit
end

#  Loop over the bundle and display the FROM and SUBJECT of each.

for i in 0 .. bundle.get_MessageCount() - 1

    email = bundle.GetEmail(i)
    print email.ck_from() + "\n";
    print email.subject() + "\n";
    print "--" + "\n";

end

#  Disconnect from the IMAP server.
imap.Disconnect()
