第一次使用csdn写文章,写得不好还请见谅。(运行环境:python3.6)
下了一个带密码的压缩包文件,作为一个刚学python的新手,想着能不能用python暴力破解它,于是在网上搜了很多资料,看着似乎并不是很麻烦,也想试着自己写一个可以暴力破解的程序,在写的过程中却遇到了各种各样的问题,希望大手们能带带我。遇到的问题如下:
- zipfile和zipfile2似乎都不支持AES解密(https://bugs.python.org/issue9170)
- 在用rarfile暴力破解时即使密码错误也不抛出异常,因此无法用try,except捕获密码
本来是想写一个可以同时暴力破解zip和rar的程序,在试了半天解密zip却一直提示密码错误之后放弃了zip,想着能不能写一个暴力破解rar的程序。
首先是生成字典:要用到itertools模块

import itertools as its import string def createDict(path,repeats,words): dict = its.product(words,repeat = repeats) '''这里的words是要迭代的字符串,repeats是生成的密码长度,生成的dict是一个返回元组的迭代器''' f = open (path, 'a' ) for cipher in dict : f.write(' '.join(cipher) + ' \n') f.close() def main(): numbers = string.digits #包含0-9的字符串 path = '输入你的字典路径' length = 你要迭代的密码长度 for i in range ( 1 ,length): createDict(path,i,numbers) if __name__ = = "__main__" : main() |
到这里我们的字典已经生成完毕了,接下来开始暴力破解rar

from threading import Thread from unrar import rarfile import os '''首先我们要读取字典,字典可能太大因此我们采用迭代器''' 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) ''' 事实上我在尝试时似乎从来没有到达过else,这样可能是得不到解压密码的。我的 一种得到密码的想法如下,但是运行效率可能会降低 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可以设置为fp.namelist()[0] 并且该方法不能使用多线程,因此速度会降低很多 ''' def main(): extract_path = '你要解压的路径' dict_path = '你的字典路径' filename = '你的rar路径' fp = rarfile.RarFile(filename) pwds = get_pwd( dict ) '''使用多线程可提高速度''' for pwd in pwds: t = Thread(target = rar_file,args = (fp,pwd,extract_path)) t.start() |
以上是写程序的思路和遇到的各种坑,代码是手敲的,可能有一些错误,希望能得到谅解和帮助。
下面是一个图形界面的rar解密源代码:(图形只是想练习,运行较慢,建议直接运行上面的函数)
