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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Mime')
loMime = CreateObject('Chilkat.Mime')

* Load the MIME
lnSuccess = loMime.LoadMimeFile("encrypted.mim")
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    RELEASE loMime
    CANCEL
ENDIF

* Decrypt using a specific PFX file:
lcPfxPassword = "myPassword"
lnSuccess = loMime.DecryptUsingPfxFile("c:/myPfxFiles/myCertAndPrivateKey.pfx",lcPfxPassword)
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    RELEASE loMime
    CANCEL
ENDIF

* Display the decrypted MIME:
? loMime.GetMime()

* Note: The MIME to be decrypted should look something like this
* when viewed in a text editor:
* (Note that the Content-Type is application/x-pkcs7-mime)

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