This is what has been sent via POST. You can see that the var names have been sent however the values are protected.<br />
<br />
<pre>
<?php
		print_r($_POST);
?>

<br />
<br />
It is not possible to expose them all at once as they have been done individually. You should also note that the kill<br />
value sent has been digitally signed with it's own key, thus keeping it from being read by anyone without the key.<br />
<br />
<pre>
<?php
		echo '$_POST["devil"] = ' . $shield->expose($_POST['devil'])."<br />";
		echo '$_POST["goto"] = ' . $shield->expose($_POST['goto'])."<br />";
		echo '$_POST["kill"] = ' . $shield->expose($_POST['kill'], false)." - no key<br />";
		echo '$_POST["kill"] = ' . $shield->expose($_POST['kill'], false, 'Secret Target')." - correct key<br />";
		exit;
	}
?>
</pre>
This example creates a get string for the form action param.<br />
