If this is possible, one might can do this, of course. Though, this procedure has to be repeated if the WRS-format changes.

Why don't you post your findings here? The first rule in cryptography is to publish protocols and how cryptosystems work so that possible attacks become visible and new procedures and algorithms can be used instead or old ones are being optimized to prevent future attacks.

Note: I do not provoke anyone to steal assets from foreign WRS-files or gamestudio games - I just think out loud that if it is in fact easy to break the WRS protection scheme why it should'nt be more secure..

I do not know if it's right to share my findings here, but if there is no objection from community and JCL i can share them.

I don't care much for models, levels and the like, you can easily unzip all Quake3 art files for example, but I don't want my code to be stolen. I thought the whole code gets compiled into unreadable machine code, am I wrong?

yes for lite-c, no for wdl.

all code gets compiled in lite-c, but in c-script it's in the wrs file.

If there is a way to "crack" it, its better to state it,
so a new encryption can be designed,
than keeping it like it is, and have others use it uncrontrolled.

I suppose it just a matter of improving the current
packer, to make it save again.

you can't really call the current wrs format encrypted. it looks more like a crude custom packing algorithm with some simple tricks like a substitution cipher for filenames. there also are those bit fields which tell if the following characters are used as-is or if they are offset/length pairs. you don't really have to be a cryptographer to figure it out.

why not simply use password protected zip files instead? would it be much slower?

Yes, zip loads slower than WRS. A hard, uncrackable encryption would also make WRS loading somewhat slower, although we could implement this if required.

optional WRS versions would probably be the best solution

some shifting/shuffling based on the username/license password before or after compressing the data may be sufficent and fast enough if the key is saved in the exe/dll and not in the wrs.

Guys is there any program that will pack my game in one .exe application? I use Extra version of Game Studio (so I use lite-c). I do not want any one to use my script from my current project. Molebox doen't work for me
