Open Source / Free Tools For Password Recovery - 7z, Rar, Uif


Recommended Posts

Does anyone have any suggestions for open source / free password recovery tools for archived file systems?

7z, RAR, ZIP, UIF, Etc?

What I have tried so far is Backtrack 5s FCRACKZIP and from the internet RARCRACK-0.2.

Fcrackzip keeps erroring out on the file saying - "is not a zipfile ver 2.xx, skipping". And Rarcrack only seems to allow brute forcing. I have compiled a dictionary that I would like to use but have encountered the aforementioned problems.

Also, if I remember correctly their use to be demo's for password recovery programs that would tell you how long the recoverable password was and the first 3 or 4 characters. Does anyone remember or know if they still exist - it would make brute forcing more targeted.

Thank you,

I use Crark to recover .RAR, the nice thing about this utility is that it uses the CUDA architecture to speed up the recovery process.


On the other side of the scale we have ElcomSoft, cracks almost anything but its not free.
