is a good key is not a probleme juste but it works randomly

on the script

   $open = fopen("php\key\keyfile.txt", "r");
  $okey=fgets($open,255);
  $td  = mcrypt_module_open('rijndael-128', '', 'ecb', '');
  $iv  = str_repeat("\x00", 16);

  $key = pack("A*",$okey); ## **not working**

  $key = $key . str_repeat("\x00", 32 - strlen($key));
  mcrypt_generic_init($td, $key, $iv);
  $key = mcrypt_generic($td, $key);
  $key = str_repeat(substr($key, 0, 16), 2);
  mcrypt_generic_deinit($td);

the key is readable

test code

<?php
$key = pack('A*', 'b8e3c43ee882b09ec4e7ace525dfd45');
echo "$key"
?>

résult

[gaaara@localhost adn]$ php test
b8e3c43ee882b09ec4e7ace525dfd45

jus actualy not works

$key = $okey; ## **working**

The key is 'b8e3c43ee882b09ec4e7ace525dfd45', dont repack it, but adjust it to 32 bytes

0b8e3c43ee882b09ec4e7ace525dfd45

change the script anyway to

		$iv=array_slice(explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$swf)[1])[1])[0]),1);
		
		$key="";
		
		foreach ($iv as $c)
			{
                        $actual=sprintf("%02x",chr(hexdec(substr($c,0,2))));
			$key.=str_repeat($actual,strlen($c)/2);
							
			}
