Demonstrates how to send a signed email using a digital certificate w/ private key stored in a PFX file.

Ruby Library for Linux and MAC OS X

require 'chilkat'

#  The mailman object is used for sending and receiving email.
mailman = Chilkat::CkMailMan.new()

#  Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

#  Set the SMTP server.
mailman.put_SmtpHost("smtp.mymailserver.com")

#  Create a new email object
email = Chilkat::CkEmail.new()

email.put_Subject("This email is signed")
email.put_Body("This is a digitally signed mail")
email.put_From("Chilkat Admin <admin@chilkatsoft.com>")
success = email.AddTo("Chilkat Support","support@chilkatsoft.com")

#  Indicate that the email should be sent signed.
email.put_SendSigned(true)

#  Load a PFX file into a certificate store object.
#  Then locate the certificate matching the  sender's email address,
#  and use it for signing.
#  (a PFX file may contain more than one certificate.)
certStore = Chilkat::CkCertStore.new()
#  The 1st argument is the path of the PFX file, the 2nd arg is the
#  PFX file's password:
success = certStore.LoadPfxFile("/pfx_files/chilkatsoft_secret.pfx","secret")
if (success != true)
    print certStore.lastErrorText() + "\n";
    exit
end

# cert is a CkCert
cert = certStore.FindCertBySubjectE("admin@chilkatsoft.com")
if (cert == nil )
    print certStore.lastErrorText() + "\n";
    exit
end

#  Alternatively, 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("/pfx_files/chilkatsoft_secret.pfx","secret")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

#  This example will use the cert from the certStore...
success = email.SetSigningCert(cert)

#  Send a signed email.
success = mailman.SendEmail(email)
if (success != true)
    print mailman.lastErrorText() + "\n";
else
    #  The LastErrorText property provides information
    #  even when successful.
    print mailman.lastErrorText() + "\n";
    print "Mail Sent!" + "\n";
end
