I see your point, but if the end user is not supposed to see the data, temp files are the only solution (because end users can always display the source code of the web page).
Not always, according to some JB. There is a product named "WebLock Pro"
http://www.weblockpro.com
that encrypt webpages. It's interesting, because the creator of this technology could disable the printscreen key, so the user could not take a screen- shot of the pages protected. I've read that it's easy to override this protection scheme, but the instruction to do so are not clear.
'Evening,
By the way, talking about protection of data, Does exist a way to get the contents or the scripts of stacks opened directly in the engine, downloaded from the web?
Someone told me that it's possible to make a dump of the memory and take the data from the resulting file.
It's really possible to get a stack from a dumped memory file?
Even if it's, in theory, possible, suppose, just as an example, in between many other possibles ways :
1.- your main stack is password protected ;
2.- this stack contains substacks protected by randomly set passwords ;
3.- the mainstack herits from the substacks stack's and/or card's scripts by activating them as front and back scripts...
No sure it will be a piece of cake to rebuild all the stuff needed to get the stack cracked and runable at the same time...
I remember an hypercard stack i did so uncrackable, uncopyable, etc... that i could never restart it until i took together an old unprotected issue of it and the source code of the protected stack to build a new one... In about protecting code and apps, the key features are in the design, lots more than in the technical tasks...
Best Regards; Pierre
Thanks in advance.
