Decrypting an SWF file

i_am_parag · 06-03-2004, 10:04 PM

Hi,

This is more of a challenge and less of a problem. One of my friend has altered the header of an swf file using an exe generated using visual foxpro. This results into inability by any program (even flash player itself) to run that swf file. Only, when he decrypts the file using the same exe, the file is back into its original manner.

Do we have any other tool/method/way to do the decryption?

With warm regards,

Parag Shah

Howdy...

I don't know what your friend did, but if you do not know how he encrypted the SWF, your chance of decrypting it is very slim... Probably a brute force will be the time consuming project to do so...

As for the tool... Whichever software that can read the SWF file header and write a new SWF file should be able to do it... and you already mentioned Visual Fox Pro which should do the job just fine... But that's not what you are really asking, is it???

You can alter the swf file using Sothink SWF quicker.

No it can decompile the swf file. But cant decompile the code if that is encrypted using swfencrypt 2.0 or someone else.

A swf file is just a binary file sitting on your hdd. You can use java, c++, c#, python, perl, etc... just look up the flash .swf specifications and it will tell you which bytes to look for to find the header location and if they are missing you can just inject them into the .swf using a text buffer.

I was going to suggest sothink swf decrypter as well, but i see that is not your problem. I would go with madgett's suggestion or just have your friend decrypt it for you and send you that file.

I have been using ASV for about 7 years. I now have an swf file that has been encrypted that asv 528 cannot decrypt. I will post the swf online and if someone can decrypt the action script and still have a working swf, I will pay 20 bux. the SWF is located at http://www.jorotek.com/rpmnew.swf
