RarFile Python Module

Question

I am trying to make a simple bruteforcer for rar files. My code is...

import rarfile

file = input("Password List Directory: ")
rarFile = input("Rar File: ")

passwordList = open(file,"r")


for i in passwordList:

    try :
        rarfile.read(rarFile, psw=i)
        print('[+] Password Found: '+i)

    except Exception as e:
        print('[-] '+i+' is not a password ')

passwordList.close()

I think this has to do with my use of the module, because when I input a password list that I am 10000% sure contains the password to the rarFile, it prints the exception.

Answer 1

The real problem here is that you are catching all exceptions, not just the one you want. So use except rarfile.PasswordRequired: That will show you that the error is not a missing password. Instead there is no function read in the rarfile module.

Have a look at some Documentation. Rar encryption is per file, not per archive.

You need to create a object from the RarFile class and try the password on each file in the archive. (or just the first if you know that is encrypted)

import rarfile

file = input("Password List Directory: ")
rarFilename = input("Rar File: ")

rf = rarfile.RarFile(rarFilename)
passwordList = open(file,"r")
first_file =  next(rf.infolist)

for i in passwordList:
    password = i.rstrip()        
    try:
        rf.open(first_file, psw=password)
        print(password, "found")
    except rarfile.PasswordRequired:
        print(password,"is not a password")

When you open and read lines from a file, the "new line" character is kept at the end of the line. This needs to be stripped from each line.

for i in passwordList:
    password = i.rstrip()
    try :
        rarfile.read(rarFile, psw=password)
        print('[+] Password Found: '+password)
