昨天翻硬盘，找到一个好东西，可惜自己加了密码自己不记得了。试了几个常用的没试出来，于是写了这么个小脚本来替我尝试。。呵呵，还真给解出来了。
python脚本内容如下，跑跑自己加密的压缩包还不错

复制代码 代码如下:

-- coding: utf-8 --

import sys,os

def IsElementUniq(list):
"""
判断list中的元素是否为唯一的
"""
for word in list:
if list.count(word)>1:
return False

return True  

def GenPswList():
"""
要求用户输入词，并根据单词组合密码，只尝试四个单词来组合，并限制密码长度为20。写的比较挫
"""
psw=raw_input('input a word>')
wordlist = []
while psw:
wordlist.append(psw)
psw=raw_input('input a word>')
print wordlist

global g_pswlist  
g_pswlist = []  
for word in wordlist:  
    g_pswlist.append(word)  

for word1 in wordlist:  
    for word2 in wordlist:  
        locallist = [word1, word2]  
        if IsElementUniq(locallist):  
            tmp = word1 + word2  
            if len(tmp) < 20:  
                g_pswlist.append(tmp)  

for word1 in wordlist:  
    for word2 in wordlist:  
        for word3 in wordlist:  
            locallist = [word1, word2, word3]  
            if IsElementUniq(locallist):  
                tmp = word1 + word2 + word3  
                if len(tmp) < 20:  
                    g_pswlist.append(tmp)  

for word1 in wordlist:  
    for word2 in wordlist:  
        for word3 in wordlist:  
            for word4 in wordlist:  
                locallist = [word1, word2, word3, word4]  
                if IsElementUniq(locallist):  
                    tmp = word1 + word2 + word3 + word4  
                    if len(tmp) < 20:  
                        g_pswlist.append(tmp)  

print 'gen psw is:', g_pswlist  

def TestUnZipPack(filename):

command = ""  
for psw in g_pswlist:  
    command = "7z e -p%s -y %s" %(psw,filename)  
    print command  
    ret = os.system(command)  
    if ret == 0:  
        print 'right psw is ', psw  
        break  

def main(filename):
GenPswList()
TestUnZipPack(filename)

if name == 'main':
if len(sys.argv) != 2:
print 'argv error'
