hi.

I've created a password variable w/input text on the first frame of a swf to enable private viewing of a swf; so if you dont know the password you cant procedd to frame 2, to see the whole thing.

Is this effective?

no, your swf can probably be decompiled.

hi kglad.

i'm not sure what decompiling is exactly though i have an idea it's like breaching copyright, though i mayb wrong, so i have downloaded some decompiler software off of cnet, 'Sothink SWF Decompiler',

but am afraid to install it

because   fearful it'll mess with my system. Is that a legitimate concern, do you htink?

And, I noticed another piece of software mentioned on cnet, SWF Decompiler Magic, from http://www.flashdecompiler.us/

which isnt free, which may be useful to fix my own swfs and look at how those of others are built.

Do you think that's ok to do? I mean, is it a standard optimization/debugging technique - to use decompilers?

And, considering that one of my issues with my own swfs is that they are processor intensive due to the use of lots of FLVPlayback, timers  that regenerated objects, and plenty much goings on, do you think that a decompiler tool can help me optimize these issues when i upload my work to my website?

hi Quigley and kglad.

just downloaded Amayeta swfEncrypt6.0 Trial and will try it on a swf. Do you know if it can be used on ActionScript files such as DocumentClass.as?

And, do you know what happens with flv in a swf, flv that's NOT embedded in the swf but rather plays via an FLVPlayback component on the stage of the swf and has a source that's in a separate folder on your website, is that also as vulnerable/decompilable?

Using Firefox i was unable to access the flv on my own website, as opposed to the swf. But once it's playing in an HTML is it recoverable, if i lose it for example?


Hi,

some ineresting stuff to read: http://jpauclair.net/2009/12/11/flash-player-security-advanced-walkthrough/

downloading: I am pretty sure I can download flv from your site once I know its path ... and in order to find path, I probably just need to use firefox dev tools while viewing the swf
