the class TamperDeterrent method addThumbprint.

     *            thumbprint already. If it does, the existing thumbprint will
     *            be removed.
     * @param dest
     *            the file where the 'signed' data should be written. Can be the
     *            same as <tt>src</tt>
     * @param t
     *            the type of data the file contains

     * @throws AccessControlException

     *             dashboard logic should be calling this method.)
