// 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.
loMailman = createobject("CkMailMan")

//  Create a new email object

//  Build the basic EDI email where the body is the EDIFACT message:
lcEdiMsg = "UNB+IATB:1+6XPPC ..."
lcName = "something"
lcFilename = "something"
lcCharset = "iso-8859-1"
loEmail.SetEdifactBody(lcEdiMsg,lcName,lcFilename,lcCharset)

loEmail.Subject = "This is the subject"
loEmail.From = "Chilkat Admin <admin@chilkatsoft.com>"
llSuccess = loEmail.AddTo("Chilkat Support","support@chilkatsoft.com")

//  Indicate that the email should be sent signed.
loEmail.SendSigned = .T.

//  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.
llSuccess = loMailman.AddPfxSourceFile("/pfx_files/myCertAndPrivateKey.pfx","secret")
if (llSuccess <> .T.) then
    ? loMailman.LastErrorText
    release loMailman
    return
endif

//  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.

llSuccess = loCert.LoadFromFile("/certs/recipientCert.cer")
if (llSuccess <> .T.) then
    ? loCert.LastErrorText
    release loMailman
    return
endif

//  Indicate that the email is to be sent encrypted.
loEmail.SendEncrypted = .T.

//  Indicate that we want 192-bit 3DES encryption:
loEmail.Pkcs7CryptAlg = "3des"
loEmail.Pkcs7KeyLength = 192

//  Specify the certificate to be used for encryption.
llSuccess = loEmail.SetEncryptCert(loCert)

//  Tell the mailman to use an opaque signature (as opposed to a detached signature)
loMailman.OpaqueSigning = .T.

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

//  Send the signed/encrypted EDI email
