Free SWF Obfuscator

Question

Does anybody know of a free flash obfuscator? All I can find are commercial ones with free trials. I have done numerous google searches, and have been unable to find what I am looking for.

I know that obfuscators do not make your swf hack proof, but they make things harder.

Things I am looking for in an obfuscator:

• Unlimited obfuscations
• No time limit
• No watermark (or on the left side only! Right side is no good, same with center)
• Able to publish work (no special player needed other than standard flashplayer)

I really was surprised to see how hard it was to find a good obfuscator (tried encoder, protection, etc. instead as well) and how easy it is to find a decompiler....

It is imperative that my code be protected, at least partially, to discourage the hacking of my game.

Answer 1

A coworker did some research on the topic a few months ago, and didn't find any free SWF obfuscators. We ended up picking SWF Encrypt (http://www.amayeta.com/software/swfencrypt/) which seems to do a good job.

Answer 2

amayeta swfencrypt - http://www.amayeta.com/software/swfencrypt/ <= this one existed for a long time and is up to date

secureSWF http://www.kindisoft.com/secureSWF/download.php <== this one fulfill no time limit, but has watermark

and since actionscript format is very like javascript, you can use online free javascript obfuscator like this one to obfuscate sections of the important code http://www.javascriptobfuscator.com/Default.aspx

or you can search for more at here http://www.google.com/search?q=obfuscator+javascript

Answer 3

I found SWFProtect. It looks decent, but You'll have to test it to be sure. http://www.swfprotect.net/swf2.0/index.php

Update: Amayeta SWF Encrypt Version 4 is now being offered for free. http://www.amayeta.com/promo/mag/

Answer 4

OBFU - 1500 euros!

Amayeta SWF Encrypt Pro 5.0 - $125 USD. gets "bypassed" too

SecureSWF - Looks like the most promising right now.

Answer 6

SWF Protector from DComSoft is one of the most reliable at the moment. costs only $40 Try it!... for testing purpouses it is the best because have no trial period.. only watermark

Answer 7

As far as I know SWF Protector is the only one that breaks Flash Decompilers. At last test it with Sothinl and Trillix Decompilers. Both failed to open protected AS3 code.
