Python如何破解压缩包密码

来源：脚本之家时间：2022-05-21 12:00:42

简介：

破解rar和zip压缩包。Windows下使用PyCharm软件。

1.步骤

1.环境

指令pip install 安装。如果是rar文件需要把rar安装包下的Rar.exe和UnRar.exe，放在对应项目\venv\Scripts的路径下。import失败时，需要在File->Settings->Project Interpreter添加对应的模块。

2.判断文件格式

type = os.path.splitext(path)[-1][1:]
if type == "zip":
elif type == "rar":

3.判断是否有密码

type = os.path.splitext(path)[-1][1:]
        if type == "zip":
                fileGet = zipfile.ZipFile(path)
                with fileGet as z:
                    for l in z.infolist():
                        is_encrypted = l.flag_bits & 0x1
                        if is_encrypted:
                            print("have password ")
                            break
                        else:
                            pass
 
        elif type == "rar":
            fileGet = rarfile.RarFile(path)
            with fileGet as z:
                if z.needs_password():
                    print("have password ")
                else:
                    print("no password")
                    return

4.密码字典自己写或者下载相应的软件生成。

5.解压文件

1.zip和rar

fileGet = zipfile.ZipFile(path)

fileGet = rarfile.RarFile(path)

2.解压

fileExtr.extractall(pwd=password)

2.代码

import sys
import zipfile
import rarfile
import threading
import datetime
import os
import subprocess
import  getopt
i = 0
fileGet = ""
class MyThread(threading.Thread):
    def __init__(self, func, args, name=""):
        threading.Thread.__init__(self)
        self.name = name
        self.func = func
        self.args = args
        self.result = self.func(*self.args)
    def get_result(self):
        try:
            return self.result
        except Exception:
            return None
def extractFile(fileExtr, password, fileType):
    try:
        encodestr = str.encode(password)
        if (fileType == "zip"):
           fileExtr.extractall(pwd=str.encode(password))
        else:
            fileExtr.extractall(pwd=password)
        global i
        i = i + 1
        print("search count : %d,real password is : %s" % (i, password))
        return password
    except:
        i = i + 1
        print("search count : %d,test password : %s, err:%s" % (i, password, sys.exc_info()[0]))
        pass
def mainStep():
    path = input("please input path:")
    try:
        if os.path.exists(path) == False:
            print("%s : path error!"%(path))
            return
        type = os.path.splitext(path)[-1][1:]
        if type == "zip":
                fileGet = zipfile.ZipFile(path)
                with fileGet as z:
                    for l in z.infolist():
                        is_encrypted = l.flag_bits & 0x1
                        if is_encrypted:
                            print("have password ")
                            break
                        else:
                            pass
                fileGet = zipfile.ZipFile(path)
        elif type == "rar":
            fileGet = rarfile.RarFile(path)
            with fileGet as z:
                if z.needs_password():
                    print("have password ")
                else:
                    print("no password")
                    return
        else:
            print("file not right")
            return
        pwdLists = open("D:\Python工程\mutou.txt")
        startTime = datetime.datetime.now()
        for line in pwdLists.readlines():
            Pwd = line.strip("\n")
            t = MyThread(extractFile, (fileGet, Pwd, type))
            t.start()
            if (t.get_result() is Pwd):
                break
        endTime = datetime.datetime.now()
        timeSpan = endTime - startTime
        print("search time:%ss" % (timeSpan.total_seconds()))
    except:
       print("err:%s" % sys.exc_info()[0])
if __name__ == "__main__":
    mainStep()

1.在线调试

2.脚本运行

cmd 窗口打开方式：右键开始菜单，选择‘命令提示符（管理员）’即可。或者从开始菜单->运行->输入cmd，回车。关于 cd 命令：用于改变当前目录路径。使用方式：cd[空格][路径]。例如 cd d:/Python27/Mytest 转到该路径下。注意：如果当前盘符不是 D 盘，需要先转到 D 盘，输入 d: 回车即可。然后才可以使用 cd d:/Python27/Mytest 。输入python test.py。test.py是对应的文件名。
