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

def get_pwd(dict_path):

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)
