PKCS7 Encrypt using Multiple Certificates

See more MIME Examples

Encrypts MIME using multiple digital certificates. Calls AddEncryptCert once per certificate, followed by a call to EncryptN. The MIME may be decrypted by any owner of one of the certificates + its associated private key. 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.

;  Load one cert from a .cer file:
$oCert1 = ObjCreate("Chilkat.Cert")
$bSuccess = $oCert1.LoadFromFile("myCert.cer")
If ($bSuccess = False) Then
    ConsoleWrite($oCert1.LastErrorText & @CRLF)
    Exit
EndIf

;  Load another cert ...
$oCert2 = ObjCreate("Chilkat.Cert")
$bSuccess = $oCert2.LoadFromFile("anotherCert.cer")
If ($bSuccess = False) Then
    ConsoleWrite($oCert2.LastErrorText & @CRLF)
    Exit
EndIf

;  Tell the MIME object to use these certs for encrypting:
;  (AddEncryptCert shouldn't fail if we already know it contains
;  a valid certificate..)
$bSuccess = $oMime.AddEncryptCert($oCert1)
$bSuccess = $oMime.AddEncryptCert($oCert2)

;  Encrypt the MIME:
$bSuccess = $oMime.EncryptN()
If ($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";
