The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Software security Pen Test

Asked by AldwinM in Software/Systems Design

Tags: , ,

Hello Experts.

I am rather new to security key development and have attempted to develop a security module that protects my (.NET Win32) application via the use of encrypted System ID and User ID combinations.  The System ID is basically generated by looking at a combination of the system's CPU ID and HD Serial number. The info is broken down into 5 blocks consisting of 4-8 alphanumeric characters encrypted by 128 bit blowfish. The unique User ID is generated based on this System ID and will obviously be different for each system.  The encrypted info is stored distributively across the system registry and a few files.

I developed the module from scratch so I am not sure as to how effective it will be to thwart would be piraters.  My 2 questions are:  

1. If someone were to get hold of a few valid System ID and User ID combinations (by purchasing a few copies of the software for example), are there any tools readily available that will let them analyze the cipher and create a keygenerator of some sort? - You see these all the time for big name commercial software and I would be very naive to think that my copy protection system will be immune to this.  Please give examples.

2. Are there any utilities that allow a user to take a snapshot of a system before software is installed and then give a report of what files and registry keys were modified after a program is installed? I would like to see how easily my encrypted key information is to detect, pehaps this will help me hide it better. Again, please give examples.

Thanks in advance.
