Written by Pankaj Rawat

From rarPasswordCracker: WinRAR Password Cracker allows you to recover/crack your lost password for WinRAR/RAR files easily and effectively. The application tries to unlock your WinRAR file by two different ways. One is brute-force password recovery, which will test all possible combinations of characters. The other way is dictionary password recovery, which will test passwords from a carefully defined password lists. It is pretty easy to use, no skill needed.


I had to brute-force a rar file in a ctf so wrote some ad-hoc code in python. Works in Linux/Windows.

This program is intended to recover lost passwords for RAR/WinRAR archives of versions 2.xx and 3.xx. The program finds by the method of exhaustive search all possible combinations of characters (“brute-force” method) or using passwords from lists (“wordlist” or “dictionary” method). Self-extracting archives and multivolume archives are supported. The program is able to save a current state (you can interrupt the program at any time, and restart from the same state later).
