I've been planning on making a few games that I was going to release as shareware, where you download the whole game, but you only get to play a certain amount of the game without registering (y'know, typical shareware type of thing)...unfortunately, all of the ways that I have been thinking of for the registration process have either been cracked in the past and/or are easily crackable, and being a student, I could really do with all the cash
Does anyone know of any way that I could have some sort of protection on the software that would be difficult to crack?

Well, you surely know that there is no way to make it impossible to crack. But you could do this : if he is registred, the programm downloads the next levels (or weapons or something else), and you should combine in with another proctection (at least one)

Yes, I was aware that nothing is impossible to crack, which was why I said I wanted something that was difficult to crack
Anyway, yeah...I guess combining some methods would make it more difficult for those evil people to crack my games (if they really wanted to)

All i could say is make the free downloadable version a demo, and the full version has to be downloaded after its paid for. Cause if you have the full game, no matter how you block it, a determined person will unlock it.

I agree with Gowmars do that then make some sort of protection on the full version.
Now i saw a CRC protection in here some were thats like a code check it checks to see it some one has reversed your code to try and remove the protection.
If the code is not the same as the CRC check loooks at it then stops them from runing the code.
How it does this i dont know But like i said i have seen a post that said CRC check for DB or DBP programs.

I would like to tell u more about how they remove protections but some one would use it in bad ways

But i am here to help so when u have put the protection in post about how this needs to be tested i will down load it try and crack it and tell u how hard it was but i am no expert.

Heh-heh. Well, when it comes right down to it, nothing one can dream up cannot be cracked. About all you can do is stop the casual user from spreading it around and even that has only a limited life before someone defeats it. The dual download process is about the only solution as you mentioned, but even that can raise difficulties eventually.

Having researched all this a long time ago I'll give you my input . If you want the whole game to be in the shareware, triple security. Personally I would go with Gowmars idea even though it's a little messy, but it works!

HEY! I just thought of something. Okay, first youll need an FTP account at DBspot or something. Do something like this:

1. have an algorithm that makes your CD-keys.
2. When a person first RUNS the program, they have to enter the
CD key.
3. then make a file whose filename contains your cd-key.
4. have it connect to your FTP site.
5. check if the file with the same name exists in the ftp directory.
6. if it already does, meaning it was illegally distributed, then END the program.
7. if it does not, then run the game as usual, AND send the file to your FTP directory.

Hope that made sense! Sorry, the idea just flashed in my mind and I couldnt really describe it very well...


BTW, only problem with this is re-installing...ill figure something out though..
