[Python] 记一次用python破解zip文件密码的经历

复制代码
import zipfile

# 创建文件句柄
file = zipfile.ZipFile("测试.zip", 'r')
# 提取压缩文件中的内容，注意密码必须是bytes格式，path表示提取到哪
file.extractall(path='.', pwd='123'.encode('utf-8'))

复制代码
import zipfile
import itertools
from concurrent.futures import ThreadPoolExecutor

def extract(file, password):
    if not flag: return
    file.extractall(path='.', pwd=''.join(password).encode('utf-8'))


def result(f):
    exception = f.exception()
    if not exception:
        # 如果获取不到异常说明破解成功
        print('密码为：', f.pwd)
        global flag
        flag = False


if __name__ == '__main__':
    # 创建一个标志用于判断密码是否破解成功
    flag = True
    # 创建一个线程池
    pool = ThreadPoolExecutor(100)
    nums = [str(i) for i in range(10)]
    chrs = [chr(i) for i in range(65, 91)]
    # 生成数字+字母的6位数密码
    password_lst = itertools.permutations(nums + chrs, 6)
    # 创建文件句柄
    zfile = zipfile.ZipFile("加密文件.zip", 'r')
    for pwd in password_lst:
        if not flag: break
        f = pool.submit(extract, zfile, pwd)
        f.pwd = pwd
        f.pool = pool
        f.add_done_callback(result)
