Using Flash Obfuscation
So what exactly does obfuscation mean? To obfuscate is to make something confusing or difficult to understand. Many of the products we will look at use obfuscation to hide your code from decompilers. Here is a rundown of several effective tools to help prevent Flash theft:

ActionScript Obfuscator
This is a tool that scrambles ActionScript. It primarily scrambles variable names and other text references into strings that are difficult to reverse engineer. Rather than provide bulletproof protection again code theft, it discourages the user from figuring the code by scratch.

Tevas v.0.9
Tevas uses two very secure algorithms (the MD5 Message-Digest Algorithm and the TEA encryption algorithm) to encrypt passwords hard-coded in your Flash movie. It can also be used to encrypt Flash text. This product is currently freeware that will eventually be integrated into the ActionScript Obfuscator (see above)

Viewer Screwer
Viewer Screwer is a free online utility written by Marcel Debreuil. The program scrambles ActionScript into machine-readable source code. Specifically, it replaces all variable names and identifiers with a scrambled sequence of letters, which ultimately makes it very difficult to reverse engineer your ActionScript. You can access the application using the following username/password, which has been published in his public forum:
username: rmb
password: password

FLASM
FLASM is an open source assembler/disassembler that allows you to decode Flash on a very low level. Your Flash movie normally relies on branched instructions and a consistent flow. If you are comfortable with assembly programming, you can obfuscate your Flash movie by manipulating the sequence and execution of instructions, thus creating irreducible loops. In layman's terms, your Flash movie will resemble byte-code spaghetti, which will confuse most disassemblers.

Macromedia Flash MX 2004
Macromedia has recently implemented measures to protect Flash source code with the release of Flash MX 2004 Professional. This product incorporates support for compiled components and the SWC format. Flash developers can now create compiled code modules with built-in code hiding. With this release, Macromedia has created a new viable market for the sale of stand-alone Flash modules and products.

A Flash .swf, made with Flash 5 or MX, can be protected equally as well. However, it is a bit more difficult.

First, you can check to see if the .swf file is on your server. Do this by checking the _root._url property.

okToPlay = FALSE;
siteURL = "http://myserver.com";
if (_url.substr(0,siteURL.length) == siteURL) {
okToPlay = TRUE;
}
if (!okToPlay) {
getURL("http://myserver.com/stolen.html");
}


You can check for multiple site URLs, like "myserver.com" and "www.myserver.com".

So that takes care of someone stealing the .swf file and placing it on their server. However, someone could still make an OBJECT/EMBED tag that links to the .swf on your server.

Unfortunately, there is no externalParamValue function in Flash. So you can't read the "src" tag.

However, you can pass variables into Flash using the URL. For instance, "mymovie.swf?id=7&" will load the movie mymovie.swf, with the variable "id" equal to 7.

You can use this to secure your games a little better. Just include the "?id=7&" BOTH your OBJECT and EMBED tag on the HTML page. Then check in the Flash movie to see if "id" equals 7.

if (id == 7) {
okToPlay = TRUE;
}


If someone steals your game by linking to the .swf on your site, they will most likely copy the "?id=7&" portion of the tag as well.

However, you can open up the Flash movie, change it to check for id == 8, and then change your HTML page to read "?id=8&". So the game still works on your site, but not theirs. They can always change it to match, but chances are it won't be worth it to them to try to keep up with you. You always have the upper hand.

nu exista decompilator care sa-ti faca fla functional.

asolite obfuscator, este free shi destul de eficient.o alta solutie este ca sa utilizezi cat mai putine imagini, iar animatiile sa fie facute cu scripturi cat mai complexe, action script azi permite desene extrem de complexe facute doar cu scripturi, uite aici un ex.:http://www.levitated.net/daily/levCityLines.html, cine stie sa faca asa ceva, nu-l mai fute grija sa fure swf urile tale amarate

corect. totusi.. nu cred ca pe tot Earth-u' nu i-a venit nimanui o idee cum sa-si protejeze munca (normal, ma refer la flash)

de zeci de ani se chinuie casele de discuri sa protejeze cd-urile, rezultat.....zero, de zeci de ani se chinuie microsoft sa-si protejeze softurile, rezultat....zero, so...ramane acelasi raspuns: daca ei banii pe ele poate sa se spele pe cap cu ele(oricine)
