how to decrypt and decode png files to real file (.ass)

(http://stream-recorder.com/forum/showthread.php?t=16727)

Re: how to decrypt and decode png files to real file (.ass)

I tried several Times with denobis hints without result.
I 'can't get the decryption Key :/

Re: how to decrypt and decode png files to real file (.ass)

Try http://www.mediafire.com/download/o7...2/adnivkey.exe

Usage

adnivkey --login=login --pass=pass

if you are in France add --noproxy

The ivkey now is 73e13fae869893a5d9d1bc7d9cb96836

Re: how to decrypt and decode png files to real file (.ass)

I works!
Thank you very much Denobis, for your work and your patience :)

Re: how to decrypt and decode png files to real file (.ass)

@denobis : i have test your key but i have another problem

$key = 73e13fae869893a5d9d1bc7d9cb96836

shell dos :

error ligne xx e13fae869893a5d9d1bc7d9cb96836

Re: how to decrypt and decode png files to real file (.ass)

hello

i have a probleme with key générated of your script dénobis

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

on the script

Code:

   $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

Code:

<?php

$key = pack('A*', 'b8e3c43ee882b09ec4e7ace525dfd45');

echo "$key"

?>

résult

Code:

[gaaara@localhost adn]$ php test

b8e3c43ee882b09ec4e7ace525dfd45

jus actualy not works

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

0b8e3c43ee882b09ec4e7ace525dfd45

change the script anyway to

Code:

                $iv=array_slice(explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$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);

                                                        

                        }

Re: how to decrypt and decode png files to real file (.ass)

What I have to replace exactl

Code:

<?php



//get the encryption key

$swf=file_get_contents("mulutibu_v4_3.swf");

$swf        = bin2hex(gzuncompress(substr($swf,8)));

        if (!strpos($swf,"62052404d3a215d3ffff620848")) die("bad");

        

                $iv=explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$swf)[1])[1])[0]);

                

                $key1="";

                

                foreach ($iv as $c)

                        {

                        $actual=chr(hexdec(substr($c,0,2)));

                        $key1.=$actual;

                        if (strlen($c)>2)

                                $key1.=$actual;                                                        

                        }



echo "\r\nivkey:".trim($key1);

        echo "\r\nThe key is in the file adnivkey.txt";

                file_put_contents("adnivkey.txt", trim($key1));



?>

this part ?

Code:

$iv=explode("24",explode("5620",explode("d030",explode("62052404d3a215d3ffff620848",$swf)[1])[1])[0]);

                

                $key1="";

                

                foreach ($iv as $c)

                        {

                        $actual=chr(hexdec(substr($c,0,2)));

                        $key1.=$actual;

                        if (strlen($c)>2)

                                $key1.=$actual;                                                        

                        }

i have edited the files and get this

Code:

ivkey:0609070904010801000000000900050506010202060600040003070000070800

and test not working

I do not understand why the script can not decrypt the file

Re: how to decrypt and decode png files to real file (.ass)

Send me a valid mulutibu.swf
