	# to test a security hack uncomment the script below, these are just a few
	# examples of what someone trying to reverse engineer the license key could
	# do. and if the make_secure function is not called they could easily know
	# how to if they knew enough about this class and php.
	
	# TEST 1 -------
	# note how the hash_key1 that is used to encrypt the license key no longer
	# exists thus helping eliminate reverse engineering of the key. It's not just
	# the hash keys, but also every other value.

	#echo "The License Key ID is : ".(empty($application->ID1) ? '<i>empty</i>' : $application->ID1).'<br />';
	
	# TEST 2 -------
	# attempts to use a restricted function 
	# declaring the obj, notice how it terminates the script
	
	#trace_r($application->_unwrap_license(file_get_contents('license.generated.dat'), 'KEY'));
	
	# TEST 3 -------
	# this test attempts to recreate a new key by loading the generate class and 
	# in declaring the obj, notice how it terminates the script
