HackBar is a toolkit to do day-to-day text-conversions and pentests
faster. It is not a quick-hack tool or something that will guide you
step by step. To use it with success you need to know what you are
doing and understand the vulnerabilities you are looking for.
There are some excellent tutorials on YouTube. I suggest you have a
look at those. (I.E. http://www.youtube.com/watch?v=7dLqyRCzx0U)
