1、单线程破解纯数字密码

注意：不包括数字0开头的密码

import zipfile,time,sys
start_time = time.time()
def extract():
  zfile = zipfile.ZipFile('IdonKnow.zip')#读取压缩包，如果用必要可以加上'r'
  for num in range(1,99999,1):
    try:
      pwd = str(num)
      zfile.extractall(path='.',pwd=pwd.encode('utf-8'))
      print ("当前压缩密码为：",pwd)
      end_time = time.time()
      print ('单线程破解压缩包花了%s秒'%(end_time-start_time))
      sys.exit(0)
    except Exception as e:
      pass
if __name__=="__main__":
  extract()

破解结果：

2、多线程破解纯数字密码

注意：不包括数字0开头的密码

import zipfile,time,threading

start_time = time.time()
flag = True # 用于判断线程是否需要终止，为True时程序执行

def extract(password, file):
  try:
    password = str(password)
    file.extractall(path='.', pwd=password.encode('utf-8'))
    print ("当前压缩密码为：",password)
    end_time = time.time()
    print ('多线程破解压缩包花了%s秒'%(end_time-start_time))
    global flag
    flag = False#成功解压其余线程终止
  except Exception as e:
    pass
def main():
  zfile = zipfile.ZipFile("test.zip", 'r')
  for number in range(1, 99999,1):
    if flag:
      thr1 = threading.Thread(target=extract, args=(number, zfile))
      thr2 = threading.Thread(target=extract, args=(number, zfile))
      
      thr1.start()
      thr2.start()
      
      thr1.join()
      thr2.join()
if __name__ == '__main__':
  main()

破解结果：

提示：多线程对数字型的运算没有多大帮助

3、破解英文+数字型的密码

import random,zipfile,time,sys

class MyIter():
  cset = 'abcdefghijklmnopqrstuvwxyz0123456789'
  def __init__(self,min,max):#迭代器实现初始方法，传入参数
    if min < max:
      self.minlen = min
      self.maxlen = max
    else:
      self.ninlen = max
      self.maxlen = min
  def __iter__(self):#直接返回slef实列对象
    return self
  def __next__(self):#通过不断地轮循，生成密码
    rec = ''
    for i in range(0,random.randrange(self.minlen,self.maxlen+1)):
      rec += random.choice(MyIter.cset)
    return rec
def extract():
  start_time = time.time()
  zfile = zipfile.ZipFile('test1.zip','r')
  for password in MyIter(1,4):#随机迭代出1~4位数的密码，在不明确位数的时候做相应的调整
    if zfile:
      try:
        zfile.extractall(path='.',pwd=str(password).encode('utf-8'))
        print ("当前压缩密码为：",password)
        end_time = time.time()
        print ('当前破解压缩包花了%s秒'%(end_time-start_time))
        sys.exit(0)
      except Exception as e:
        print ('pass密码：',password)
        pass
if __name__=="__main__":
  extract()

破解结果：
