Send Signed and Encrypted EDI Email (EDIFACT)

Demonstrates how to send a signed and encrypted EDI email (EDIFACT email). Visual FoxPro

* 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('Chilkat.MailMan')

*  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>"
lnSuccess = loEmail.AddTo("Chilkat Support","support@chilkatsoft.com")

*  Indicate that the email should be sent signed.
loEmail.SendSigned = 1

*  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.
lnSuccess = loMailman.AddPfxSourceFile("/pfx_files/myCertAndPrivateKey.pfx","secret")
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    CANCEL
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.

lnSuccess = loCert.LoadFromFile("/certs/recipientCert.cer")
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loMailman
    CANCEL
ENDIF

*  Indicate that the email is to be sent encrypted.
loEmail.SendEncrypted = 1

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

*  Specify the certificate to be used for encryption.
lnSuccess = loEmail.SetEncryptCert(loCert)

*  Tell the mailman to use an opaque signature (as opposed to a detached signature)
loMailman.OpaqueSigning = 1

*  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 = 1

*  Send the signed/encrypted EDI email
lnSuccess = loMailman.SendEmail(loEmail)
IF (lnSuccess <> 1) THEN
    ? loMailman.LastErrorText
ELSE
    ? "Mail Sent!"
ENDIF
