Re[2]: [Flashcoders] Prevent flash from caching the loaded assets
Base64 is superfluous here, since you can load raw binary data - see
URLLoader.dataFormat.

A solution is to convert the image into a textfile which is then used to draw
the image on the screen using bitmap drawing tools.
This, of course, is easily hacked by anybody with a copy of Flash because
they can read your textfile and draw the bitmap
themselves.
The next step is to encrypt that textfile. Problem is, you have to put your
decryption code inside of Flash, which is, of course,
easily hacked by anybody with a free copy of SoThink.
You cannot make secure games in Flash unless all logic is on the server and
Flash becomes a dumb interface. This isn't going to
be possible with your game because you're using a mask to reveal an image.
You're also trying to control the browser and the OS
file system from inside a plug-in running in that browser. Give up on that
idea.
Basically, you're trying to secure an open file format (swf). You cannot do
this. Any swf files you put on any public server can
be downloaded and decompiled by anyone. Flash source code is never safe.
If you don't like that Flash isn't secure and is an open-format, then I
suggest you write a letter to Adobe, ATTN: Circular File.
In other words, forget it. Flash is not secure because it is open and that's
how it is. If you want to do something like this,
you will have to use a lower-level technology, but I'm doubtful a Java
plug-in will support what you're trying to do, either.

Re: Re[2]: [Flashcoders] Prevent flash from caching the loaded assets
You can't send raw binary data over http, it has to be Base64 encoded.
This part is required in the Coldfusion page:
cfset img64 = toBase64(imgBinary) /
cfoutput#img64#/cfoutput
Coldfusion throws an error when using the following:
cfsetting enablecfoutputonly=yes showdebugoutput=no
cfset imgPath = ExpandPath (leaves.jpg) /
cffile action=readBinary file=#imgPath# variable=imgBinary
cfoutput#imgBinary#/cfoutput
quote
ByteArray objects cannot be converted to strings
/quote
If you'd use remoting or a socket, then the Base64 encoding is not required.

Re[4]: [Flashcoders] Prevent flash from caching the loaded assets
I don't know what Coldfusion can do or cannot do (I'm not familiar
with it), but HTTP _is_ capable for sending binary data without
any encodings. So if you cannot send binary data from Coldfusion then
it is a limitation in Coldfusion itself and not in HTTP.
However if you are using base64 here as an encryption for making
harder to obtain the downloaded image from browser's cache, then
that's OK :)

Just saw this solutions. This is what I need. No caching on the client.
We try to implement this solution in our project. I'll let you know if
works also with PHP.

Re: [Flashcoders] Prevent flash from caching the loaded assets
Yes, the SWF would be easy to decompile, but I think as soon as you start worrying about someone decompiling the SWF to cheat you're pretty much out of luck, as they can always decompile your game's SWF instead and find out everything there is to know about the game. That would probably give them a lot more options for cheating. :) If you want to go the AMFPHP route (which I'm not familiar with at all) and sending a large array is having problems, why not split it up? Send a couple smaller arrays and then combine them on the client side. -Andy On 8/6/07, Niels Endlich [EMAIL PROTECTED] wrote: It seems to me that the swf is easy to decompile and the photo also...

Re: [Flashcoders] Prevent flash from caching the loaded assets
I think the caching is controlled by the browser, not Flash itself, so I don't believe there's a way within flash to prevent caching. Maybe you could do some trickery with the images that makes it harder for the person looking at the cached stuff to see it. Like, split up the main image into multiple ones and maybe apply some transformations to the images, and then have the flash movie undo the transformations and compose the images back into the main one? -Andy On 8/6/07, Niels Endlich [EMAIL PROTECTED] wrote: We are making a game in which people have to quess what's on a photo while viewing it through a little moveable hole.

Re: [Flashcoders] Prevent flash from caching the loaded assets
If you're using AS3, then load the image via flash.net.Socket (a direct socket connection to the server) rather than via the normal image loading mechanism - then use loadBytes() on the Loader class? I think that gets around it.

RE: [Flashcoders] Prevent flash from caching the loaded assets
If you're able to store the images in SWF format instead of something like JPG, you could set up your SWFs so that they're covered with a black rectangle MovieClip by default and then you flip the _visible property to false in your application when you load them in. That way, if people try to look at the SWF from the browser's cache, they'll just see a big black rectangle but within your app, the photo is visible. Just a thought.

Of course, that doesn't really prevent caching as much as it prevents the broswer from handing Flash a cached copy the next time it is loaded. Jack's concept of a swf with a black foreground is a good one tho'. -- Troy RPSystems, Ltd. http://www.rpsystems.net ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

RE: [Flashcoders] Prevent flash from caching the loaded assets
It seems to me that the swf is easy to decompile and the photo also... We were working on sending an array with amfphp which contains the pixel information and use BitmapData setPixel to plot the image. But it seems that AMFPHP isn't able to send such a large array (800x600pix). Has anyone done somthing like this before? -Oorspronkelijk bericht- Van: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Namens eric e. dolecki Verzonden: maandag 6 augustus 2007 20:51 Aan: flashcoders@chattyfig.figleaf.com Onderwerp: Re: [Flashcoders] Prevent flash from caching the loaded assets http://foo.domain.com/images/imageContainer.swf?e=; + getDate() all images could be in 1 swf and called out.
