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

Dim mime As ChilkatMime
mime.Initialize

'  Create a simple MIME message to be encrypted:
success = mime.AddHeaderField("Content-Type", "text/plain")
success = mime.AddHeaderField("abc", "123")
mime.SetBody("This is a test")

Dim cert As ChilkatCert
cert.Initialize("cert")
success = cert.LoadFromFile("qa_data/pem/mf_public_rsa.pem")
If success = False Then
    Log(cert.LastErrorText)
    Return
End If


'  Encrypt the MIME.
success = mime.Encrypt(cert)
If success = False Then
    Log(mime.LastErrorText)
    Return
End If


'  Display the MIME:
Log(mime.GetMime)

'  The resulting S/MIME looks like this:

'  Content-Type: application/x-pkcs7-mime; name="smime.p7m"; smime-type="enveloped-data"
'  abc: 123
'  Content-Disposition: attachment; filename="smime.p7m"
