Is it possible to reverse-engineer?

Is it possible to reverse-engineer a flash file?

Like, if I put a flash file on a site, and someone wants to look at the code I used to make it, can they somehow decomplie the thing?


I ask because I was wondering about the password-protection flash movie, and I was wondering if it would be possible for someone to discover a password by breaking apart the movie.


Thanks!

Certainly.

Do a search for ActionScript Obfuscator in the software section of this site. That program essentially scrambles all the actionscript in the swf file.

Good luck.

Thanks a ton!

Crud...! They don't provide it anymore...Can someone else give me a copy, perchance? :) Thanks!

It's my understanding that a swf file is a compiled executable, not unlike an applet. And the password is just for protecting from import.

You're right. Except just like a exe with a hexidecimal editor, you can see some of the workings of that. And there are programs to extrapolate that information from swf files. So, if what you're looking to do is prevent it from import, there are some things you can do. Such as putting a condition in your movie that detects what URL it's at and allowing it to play or not regarding the "answer" you get.

Good luck guys.

So, does the obfuscator make swf files larger?

To your first piont though Jerry, I think someone smart enough to somehow extrapulate code from a swf file from the internet, problaby already knows how to program anyway, to your second about file size, code is minute in size, it is of course picture and sound files that take up so much space..
