' 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")
set mime = Server.CreateObject("Chilkat.Mime")

' Load the MIME
success = mime.LoadMimeFile("encrypted.mim")
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( mime.LastErrorText) & "</pre>"
    Response.End
End If

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.FileAccess")
set fac = Server.CreateObject("Chilkat.FileAccess")
pfxData = fac.ReadEntireFile("pfxStore/myPkcs12.p12")
If (fac.LastMethodSuccess <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( fac.LastErrorText) & "</pre>"
    Response.End
End If

pfxPassword = "myPassword"
success = mime.DecryptUsingPfxData(pfxData,pfxPassword)
If (success = 0) Then
    Response.Write "<pre>" & Server.HTMLEncode( mime.LastErrorText) & "</pre>"
    Response.End
End If

' Display the decrypted MIME:
Response.Write "<pre>" & Server.HTMLEncode( mime.GetMime()) & "</pre>"

' 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"
