# 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 = New-Object Chilkat.MailMan

#  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.Subject = "This is the subject"
$email.From = "Chilkat Admin <admin@chilkatsoft.com>"
$success = $email.AddTo("Chilkat Support","support@chilkatsoft.com")

#  Indicate that the email should be sent signed.
$email.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 -ne $true) {
    $($mailman.LastErrorText)
    exit
}

#  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 -ne $true) {
    $($cert.LastErrorText)
    exit
}

#  Indicate that the email is to be sent encrypted.
$email.SendEncrypted = $true

#  Indicate that we want 192-bit 3DES encryption:
$email.Pkcs7CryptAlg = "3des"
$email.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.OpaqueSigning = $true

#  SMTP server (use your settings and refer to the online
#  reference  documentation for more options)
$mailman.SmtpHost = "smtp.mymailserver.com"
$mailman.SmtpUsername = "myLogin"
$mailman.SmtpPassword = "myPassword"
$mailman.SmtpPort = 587
$mailman.StartTLS = $true

#  Send the signed/encrypted EDI email
$success = $mailman.SendEmail($email)
if ($success -ne $true) {
    $($mailman.LastErrorText)
}

    $("Mail Sent!")
