 1 | # Python RAR Cracker
 2 | A tiny python script for cracking rar file encrypted by a password
 3 | 
 4 | ### Dependencies
 5 | + [brute](https://github.com/rdegges/brute)
 6 | + [python-unrar](https://github.com/matiasb/python-unrar)
 7 | 
 8 | ### Usage
 9 | There are two working modes.  
10 | + In **dictionary** mode, the script loads each word in the dictionary and trys to decrypt the rarfile using that word.
11 | + In **brute** mode, the script trys every permutation of the given string set.
12 | ### Screenshot
