@Spruten : if SWF size is important for you, you can use “Flash Secure Optimizer” by eramsoft, it has more options to reduce SWF size.

For people using flex, I can recommend ‘irrfuscator’, not sure why noone mentioned it yet. Simply rewrites your source files, meaning you are able to actually even debug your actionscript code afterwards. But I’ll also try the sothink software you mentioned, didn’t try the latest version yet.

secureswf is easily the best… i use it too

(Would you be able to combine this comment with my last?) In regards to, “There’s also a few optimization features that will increase the speed and filesize of your game,” do you really mean increase the filesize? With all the junk the obfuscation seems to add, this seem plausible, but you stated it as if it were good to increase the filesize. I’m unsure of what you really meant. Thank you.

Does secureSWF add to the size of the SWF or “de-optimize” the code? Looking at the “after” portion of the before/after secureSWF, it appears it would.

I looked at the price/features comparison chart, and to get all the options you described, you pay $400… or find a cracked version, I suppose. Still, I may look into using the demo for one of my later projects.

Greetings to all,

anybody know what kind of encryption is in use in this secureSWF?

Which algorithm, AES, RSA or …?

Regards,

Ruah.

first of all thanks for answering,

okay i see how it’s done, nice. didn’t know that was possible. For the matter of the flex air, i will look about it, if i learn something new i keep in touch. same for you!

Sergio,

as I can see, it looks like it uses assembly (asm).
Don’t quote me fully on that but all the “null” is making me think that, that’s what it’s doing. changing all the code to assembly, and then compiling that. Or, could be adding a form of a bootstrap.
Personally, I just play with the SWF headers, and then add extra bytes at the end of th swf.. sometimes it messes up the swf, other times it breaks decompilers. lol. I’ve used trillix and sothink. Trillix was easier to break than sothink.

hi,

you review is great.
I just have one question, i mean you encrypt the swf and then put it encrypted on your webpage. but how does adobe player read it if encrypted? and how to encrypt an air application if possible!?
did I say one question? I meant two!
thanks
