How to protect windows desktop application from being installed on different computer when using SerialNumberTemplate property for defining key pattern? How Can I bind particular key for only one user ,so that he can use it only once i.e. for one time setup only

Answer 1

I think you need to Crack-proof/Anti-cracking logic. I should say you can't do it by your own; but you can use other simple ways:

You can search for codes/libraries about Serial Number Generators based-on the Hardware serial Numbers.

For example, check the following Internet Address:

.NET Reactor and IntelliLock

As you know, Hardware Serial Numbers are UNIQUE for every Hardware; so, with this method, the used code will generate the Unique and Specific Serial Number based-on the Hardware Serial Numbers in each system.

But I must say something, working on the Crack-proof/Anti-cracking logic is very complicated, if you want to create your own logic as well. and I should say, using existing shared codes/libraries in the Internet is at your own risk; because they are public and shared. So, may be their Crack-proof/Anti-cracking logic is found by some bodies, and has shared in the Internet.

if you want to create your own logic, you need to know about Cracking and Anti-Cracking Methods. Today, developers use hybrid methods by combining several methods together. In the modern programs like MS Office, MS Windows OSes or etc. developers use many logic for preventing from cracking the software such as:

• Checking by the Internet and adding some codes to the updates for finding cracked parts of the program
• Checking the Hardware Serial Numbers for generating the UNIQUE Serial Number in a very secure and complex method
• Creating many JUNK Threads for hide and difficult to find the Data Flow Process of the License Information by Data Flow Checker, Disassembler or Debugger applications like SoftICE
• Creating some Licensing Services for run and check the running processes for detecting cracking software or check Licensing and other related things to prevent cracking
• And many other methods

A strong and powerful Cracker knows Assembly programing language, using Disassembler or Debugger applications, the Data Flow Process logic and the Internet connecting methods in the application programs and Targeted OSes, and so on as well.
