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

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

#  Create a new email object

#  Build the basic EDI email where the body is the EDIFACT message:
ediMsg = "UNB+IATB:1+6XPPC ..."
name = "something"
filename = "something"
charset = "iso-8859-1"
email.SetEdifactBody(ediMsg,name,filename,charset)

email.put_Subject("This is the subject")
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)

#  Tell the mailman to use a PFX file as a source for locating
#  the certificate and private key required for signing.
#  The certificate chosen for signing will be the one that
#  matches the sender's email address, which also has
#  a private key.  All intermediate certs in the chain of
#  authentication, up to and including the root, will
#  be included in the signature.
success = mailman.AddPfxSourceFile("/pfx_files/myCertAndPrivateKey.pfx","secret")
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

#  Load the .cer file into a certificate object.
#  When sending S/MIME encrypted email, it is the recipient's
#  certificate that is used for encryption.  Only the public key
#  is needed to encrypt.  The recipient is the only
#  one possessing the private key, and therefore is the only
#  one able to decrypt.

success = cert.LoadFromFile("/certs/recipientCert.cer")
if (success != true)
    print cert.lastErrorText() + "\n";
    exit
end

#  Indicate that the email is to be sent encrypted.
email.put_SendEncrypted(true)

#  Indicate that we want 192-bit 3DES encryption:
email.put_Pkcs7CryptAlg("3des")
email.put_Pkcs7KeyLength(192)

#  Specify the certificate to be used for encryption.
success = email.SetEncryptCert(cert)

#  Tell the mailman to use an opaque signature (as opposed to a detached signature)
mailman.put_OpaqueSigning(true)

#  SMTP server (use your settings and refer to the online
#  reference  documentation for more options)
mailman.put_SmtpHost("smtp.mymailserver.com")
mailman.put_SmtpUsername("myLogin")
mailman.put_SmtpPassword("myPassword")
mailman.put_SmtpPort(587)
mailman.put_StartTLS(true)

#  Send the signed/encrypted EDI email
success = mailman.SendEmail(email)
if (success != true)
    print mailman.lastErrorText() + "\n";
else
    print "Mail Sent!" + "\n";
