JS Challenge 2 - iExploit Challenges

Here is number two:

//JS challenge two
function crack_it(bla)
{
	var i=0;
	var temp=bla&#46;length;
	for (i=0;i&lt;temp;i++)
	{
		if (i%2==0)
		{
			bla += i;
		}
	}
	return bla;
}

function login_form()
{
	var name=prompt(\"Username&#58;\",\"\");
	var pass=prompt(\"Password&#58;\",\"\");
	if (pass==crack_it(name))
	{
		alert(\"Welcome \" + name + \", you have entered the system\");
		//function to add points to the user his score
		window&#46;location=\"http&#58;//www&#46;iexploit&#46;org/index&#46;php/javascript/level-3\";
	}
	else
	{
		alert(\"Wrong password for user \" + name);
	}
}
//Coded by x3n0n

So here the key to finding your way in is by typing any username in the username field and you just have to find the password corresponding to the crack_it(var1) returnvalue. Shouldn't be that hard to complete :)

example of this:

&lt;html&gt;
&lt;head&gt;
&lt;title&gt;test&lt;/title&gt;
&lt;script type=\"text/javascript\" src=\"Challenge_two&#46;js\"&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;input type=\"button\" onclick=\"login_form()\" value=\"Login\"/&gt;
&lt;/body&gt;
&lt;/html&gt;

Howdy, Stranger!
