Send Signed and Encrypted EDI Email (EDIFACT)

Demonstrates how to send a signed and encrypted EDI email (EDIFACT email). Xojo Plugin

Dim success As Boolean
success = False

// 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.
Dim mailman As New Chilkat.MailMan

//  Create a new email object
Dim email As Chilkat.Email

//  Build the basic EDI email where the body is the EDIFACT message:
Dim ediMsg As String
ediMsg = "UNB+IATB:1+6XPPC ..."
Dim name As String
name = "something"
Dim filename As String
filename = "something"
Dim charset As String
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")

    System.DebugLog(mailman.LastErrorText)
    Return
End If

//  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.
Dim cert As Chilkat.Cert
success = cert.LoadFromFile("/certs/recipientCert.cer")
If (success <> True) Then
    System.DebugLog(cert.LastErrorText)
    Return

//  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)
