Protection Against Giving my tool to other people

[peter233]

Hello guys.

I want to code a protection that protects my Tool (which can be bought) so that my customers cannot give it to friends for free because the tool should only work on THEIR Computer !

This is my idea:

The tool gets :

- Computer Name

- Windows User Name

Then it crypt the settings with md5.

Then i send the customer a tool which generates the md5 string.

They send me the string and i write it in the tool that only the customer with this md5 string can execute it.

How i can make this?

Please help me !

Cu,

Peter

Hi,

i would do it like this:

1) Get the mac adress of customer pc from customer.

2) Built with customer mac adress and Function _StringEncrypt a key. Sent the key to customer to import in local registry.

3) At startup of your program read the local mac adress, built with Function _StringEncrypt and local mac the key and compare it with the key in localregistry

Just read help _StringEncrypt and you should get enough input.

Good luck

The mac address is somewhat easy to spoof. I'd use a combination of the first hard disk serial number and something else (maybe username or computername).

Also watermark the files, so that you can find out who leaked/cracked it !

Hi,

you are right. Although I would prefer using SID of computer and / or Username instead of real name. This should it make more safe.

Can you give me an Example?

Can you give me an Example?

the best system i think is a tcp server with a username and password database

u can use a login for the program it connects and sends the username and password

and IF the login is good then u send Connected and they may use your program

(a nice addon for this is that u can add Versions to it when the user have a old version of ur software they download a new one i have that working )

a TCP system liek this is allmost not bypassable... so that works the best for u i think

and yes i can give u an example

Start making something using _StringEncrypt and DriveGetSerial

EDIT: Lol at the advice about setting up an authenticating server. Way to go overboard ! Besides it's not difficult to crack that as well.
