Check for encryption key

Does a user have a specific encryption key attached to her ID file? Use this script function to find out.

The example displays a dialogbox showing if the current user owns encryption key "SampleKey". This could also be used to send an e-mail report on which users have a given key, or to set field values and display customized content based on whether or not the user owns the encryption key.

     Const keyname = "SampleKey"
     If UserOwnsEncryptionKey(keyname) Then
          Msgbox "Key " & keyname & " is attached to your ID file."
     Else
          Msgbox "Key " & keyname & " is not attached to your ID file."
     End If
End Sub
