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

loMime = CreateObject('Chilkat.Mime')

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

loFac = CreateObject('Chilkat.FileAccess')
loPfxData = loFac.ReadEntireFile("pfxStore/myPkcs12.p12")
IF (loFac.LastMethodSuccess <> 1) THEN
    ? loFac.LastErrorText
    RELEASE loMime
    RELEASE loFac
    CANCEL
ENDIF

lcPfxPassword = "myPassword"
lnSuccess = loMime.DecryptUsingPfxData(loPfxData,lcPfxPassword)
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    RELEASE loMime
    RELEASE loFac
    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;
