199865 RAR Password Recovery

I would like a piece of software that would enable the user to recover the password for WinRar/ Rar files. The software must be branded with my logo. I would like the piece of software to be similar to the ones listed here : [login to view URL] [login to view URL] However, the above two examples take far too long so therefore, I would like the software to be able to run in 3 ways. Firstly, I would like the software to have the option of running at maximum priority, and therefore very fast. I wouldn't mind if this consumed a lot of memory, as long as it completes the task as fast as possible. I would also like it to have the option of running at medium priority, and low priority, where it can take a long time for the task to be completed, but consumes very little memory. I would like for the software to include the estimated time remaining until completion. I would also require the software have the option of running two different ways. The password can be found via the "bruteforce" method - where all password combinations possible can be checked, or by using passwords from the english dictionary. (which must be included). For instance, before selecting a .rar file f the password to be found.. The user can select whether he/she would like to try dictionary words first. I would also require both a demo and full version. In the demo version, I would like there to be a limitation so that the software may only find 3 characters of the password... (not all of it).. and the full version must be fully functional with no limitations. Finally, I would like the software to eb neatly designed, and I am up for additional suggestions as to how the softare could be improved further. Thanks for reading, If you require more informationm, please feel free to reply.
