第一次使用csdn寫文章,寫得不好還請見諒。(執行環境:python3.6)

下了一個帶密碼的壓縮包檔案,作為一個剛學python的新手,想著能不能用python暴力破解它,於是在網上搜了很多資料,看著似乎並不是很麻煩,也想試著自己寫一個可以暴力破解的程式,在寫的過程中卻遇到了各種各樣的問題,希望大手們能帶帶我。遇到的問題如下:

  • zipfile和zipfile2似乎都不支援AES解密(https://bugs.python.org/issue9170)
  • 在用rarfile暴力破解時即使密碼錯誤也不丟擲異常,因此無法用try,except捕獲密碼

本來是想寫一個可以同時暴力破解zip和rar的程式,在試了半天解密zip卻一直提示密碼錯誤之後放棄了zip,想著能不能寫一個暴力破解rar的程式。

首先是生成字典:要用到itertools模組

import itertools as its
import string

def createDict(path,repeats,words):
	dict = its.product(words,repeat=repeats) 
	'''這裡的words是要迭代的字串,repeats是生成的密碼長度,生成的dict是一個返回元組的迭代器'''
	f = open(path,'a')
	for cipher in dict:
		f.write(''.join(cipher) + '\n')
	f.close()

def main():
	numbers = string.digits  #包含0-9的字串
	path = '輸入你的字典路徑'
	length = 你要迭代的密碼長度
	for i in range(1,length):
		createDict(path,i,numbers)

if __name__=="__main__":
	main()

到這裡我們的字典已經生成完畢了,接下來開始暴力破解rar

from threading import Thread
from unrar import rarfile
import os

'''首先我們要讀取字典,字典可能太大因此我們採用迭代器'''

def get_pwd(dict_path):
	with open(dict_path,'r') as f:
		for pwd in f:
			yield pwd.strip()

def decode_rar(fp,pwd,extract_path):
	try:
		fp.extractall(extract_path,pwd=pwd) 
	except:
		pass
	else:
		print('the pwd is>',pwd)
'''
事實上我在嘗試時似乎從來沒有到達過else,這樣可能是得不到解壓密碼的。我的
一種得到密碼的想法如下,但是執行效率可能會降低


def decode_rar(fp,pwd,check_file,extract_path):
	fp.extractall(extract_path,pwd=pwd)
	if os.path.exists(check_file):
		print('The pwd is:',pwd)
		exit(0)
其中check_file可以設定為fp.namelist()[0]
並且該方法不能使用多執行緒,因此速度會降低很多
'''

def main():
	extract_path = '你要解壓的路徑'
	dict_path = '你的字典路徑'
	filename = '你的rar路徑'
	fp = rarfile.RarFile(filename)
	pwds = get_pwd(dict)
	'''使用多執行緒可提高速度'''
	for pwd in pwds:
		t = Thread(target=rar_file,args=(fp,pwd,extract_path))
		t.start()

以上是寫程式的思路和遇到的各種坑,程式碼是手敲的,可能有一些錯誤,希望能得到諒解和幫助。
下面是一個圖形介面的rar解密原始碼:(圖形只是想練習,執行較慢,建議直接執行上面的函式)
