[Resolved] how to decrypt and decode png Solution

[hexodark]

here is the solution

<?php
function decryptSubtitle($encrypted, $key = "encryption ID ")
{
$decrypted = "";
$encryptedLen = strlen($encrypted);
$keyLen = strlen($key);
for ($i = 0; $i < $encryptedLen; $i++)
{
$dataCharCode = ord($encrypted[$i]);
$keyInt = substr($key, ($i % $keyLen) - 1, 1);
$decodedChar = chr($dataCharCode - $keyInt);
$decrypted = $decrypted . $decodedChar;
}
$decrypted = base64_decode($decrypted);
return $decrypted;
}




file_put_contents("subtitles.txt", decryptSubtitle(file_get_contents("link for your files")));
?>

and you have to load the page and the file will be created

Video streaming? I'm moving you to our subitle function.

Nope, I have no idea how to decode it.

[hexodark]

a forum member told me the following

For the subtitles you have to guess how they are encrypted and encoded.
It can be done by decompiling the flash player and finding the corresponding ActionScript function that do it and then adapt it to your own needs

I do not understand

IMHO, you should upload a copy of your problematic file(s) to this forum
(OR to elsewhere, except mega.co.nz of course).

I know nothing about ActionScript or decryption, BUT someone else may know,
and a sample file probably wouldn't be "useless" in this case.

act honestly
original author decryption script
http://stream-recorder.com/forum/showpost.php?p=63893&postcount=2

decryption script to several websites without mentioning the original author,this is not how it's supposed to be
you can't present someone else's work as your own.
