This semester, I have taken a course on Information Security and my project for this course is to implement an SQL injection to obtain admin privileges. For this I first download Havij software (Advanced SQL Injection Tool) to study how it works.
After some time and tests, I know how to hack some of the information of a website. Now, I want to create my own page of the same kind as I found in the example of Havij software at http://www.target.com/index.asp?id=123. How can I make my own page to study penetration testing and hacking of my own information so that I can learn more from it?
