LOCAL lnSuccess
LOCAL loCert

* This example requires 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')

* Create a simple MIME message to be encrypted:
lnSuccess = loMime.AddHeaderField("Content-Type","text/plain")
lnSuccess = loMime.AddHeaderField("abc","123")
loMime.SetBody("This is a test")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Cert')
loCert = CreateObject('Chilkat.Cert')
lnSuccess = loCert.LoadFromFile("qa_data/pem/mf_public_rsa.pem")
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loMime
    RELEASE loCert
    CANCEL
ENDIF

* Encrypt the MIME.
lnSuccess = loMime.Encrypt(loCert)
IF (lnSuccess = 0) THEN
    ? loMime.LastErrorText
    RELEASE loMime
    RELEASE loCert
    CANCEL
ENDIF

* Display the MIME:
? loMime.GetMime()

* The resulting S/MIME looks like this:

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