PKCS7 Encrypt MIME

Encrypt MIME using a digital certificate to create PKCS7 encrypted S/MIME. AutoIt

Local $bSuccess = False

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

$oMime = ObjCreate("Chilkat.Mime")

;  Build a simple MIME message to be encrypted:
$bSuccess = $oMime.AddHeaderField("Content-Type","text/plain")
$bSuccess = $oMime.AddHeaderField("abc","123")
$oMime.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.)

$oCert = ObjCreate("Chilkat.Cert")
$bSuccess = $oCert.LoadFromFile("myCert.cer")
If ($bSuccess = False) Then
    ConsoleWrite($oCert.LastErrorText & @CRLF)
    Exit
EndIf

;  Encrypt the MIME:
$bSuccess = $oMime.Encrypt($oCert)
If ($bSuccess = False) Then
    ConsoleWrite($oMime.LastErrorText & @CRLF)
    Exit
EndIf

;  Display the MIME:
ConsoleWrite($oMime.GetMime() & @CRLF)

;  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";
