Goran
you could try something like
http://www.ftp.cl.cam.ac.uk/ftp/papers/djw-rmn/djw-rmn-tea.html to encript
the machine ID etc. you supply the key/keys

Subject: [Dev-C++] Questions about porting to windows



Hi,

I have a Linux app written in C, with GTK, libcurl and sqlite and I want to 
port it to Windows. All libs have versions for Windows, so I made a MSYS/
MinGW enviroment and added GTK, libcurl and sqlite library. But, I have some

Windows genral programming questions.

1) In Linux, i have ./configure script that adds PACKAGE_DIR gcc define, so
I 
can use it from code to open files like this:
sqlite_open(PACKAGE_DIR "/data.db");

But on Windows I will have precompiled executable. Do I must to change paths

to load them from Windows registry and set up keys during setup, or there is

some other common procedure?

2) As it will be commercial application, I want to know how can I protect it

from copying? I want to do serial number check that will be entered on first

time use of application. But keeping some flag that the app is registered is

pointless, as everybody can just copy app from host to host.

So I had some ideas to make a algorithm that will check some system thing 
(like processor serial number, HDD serial or something other), and than 
accept only one value of serial number. So the user will have machine ID,
and 
than call service center, ask for serial number, enter it and that serial 
will work only on that computer.

Problems: well if algorithm is plain, it can be cracked so everybody will
have 
serials ;), than I donow know how to get Hardware data, and what is that 
hardware data that I can use for serial generating.

Do you have some better ideas?


Thank you,
Goran Rakic
