Protect Yii Connection String

Is there any solution to conceal connection info of oracle connection string, username & password in the main.php of Yii application?

illustration like this:

	'db'=>array


	(


	'class'=>'CDbConnection',


	'connectionString'=>'57bf064b2166366a5ea61109006b8d5c',


	'username'=>'63a9f0ea7bb98050796b649e85481845',


		'password'=>'e04ccf211208f8c97e4a36e584926e60',


	),

I managed to solve it by myself now, thanks
