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

set mime = Server.CreateObject("Chilkat.Mime")

'  Build 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"

'  A digital certificate is required to create PKCS7 encrypted MIME.
'  It can come from a variety of sources: .cer file, .pfx file, PEM files,
'  an in-memory representation, or directly from a Windows
'  registry-based certificate store.

'  This example will load a certificate object from a .cer file.
'  Note: Only the public-key is required to encrypt.  (Decryption
'  requires a private key.)

set cert = Server.CreateObject("Chilkat.Cert")
success = cert.LoadFromFile("myCert.cer")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( cert.LastErrorText) & "</pre>"
    Response.End
End If

'  Encrypt the MIME:
success = mime.Encrypt(cert)
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( mime.LastErrorText) & "</pre>"
    Response.End
End If

'  Display the MIME:
Response.Write "<pre>" & Server.HTMLEncode( mime.GetMime()) & "</pre>"

'  The resulting S/MIME looks something like this:

'  abc: 123
'  Content-Disposition: attachment; filename="smime.p7m";
'  Content-Transfer-Encoding: base64
'  Content-Type: application/x-pkcs7-mime;
'   name="smime.p7m";
