With rising problem of SWF reverse engineering, I was looking for a simple tool that does SWF protection. There are variety of tools out there, but one got the hold of my eye, so I decided to do a little testing. Not that I have something to hide, as I usually write GPL code, but when I do it for clients, then it is reasonable to mess up some sensitive code parts.
That tool is SWF Protector 3.0 which has nice interface and it is very simple to use.
According to author, it provides unbreakable protection for reverse engineering. I do not believe that, as everyting is breakable sooner or later, but for now it does the job good. It has two levels of protection, for Actionscript 2, for which I do not care about as I don’t use AS2, and two for AS3: Obfuscate and Protect.
Obfuscate does not protect SWF from decompressing and reverse engineering, but it really messes up code beyond readable. Protect protects from reverse engineering completely. Good thing is that default setting is to do both at once. However, since they increase size of the file, if size of SWF is really important, Read more…
