壓縮包密碼破解樣本分享(類似典破解)

昨天翻硬碟，找到一個好東西，可惜自己加了密碼自己不記得了。試了幾個常用的沒試出來，於是寫了這麼個小指令碼來替我嘗試。。呵呵，還真給解出來了。
python指令碼內容如下，跑跑自己加密的壓縮包還不錯

代碼如下:

# -*- coding: utf-8 -*-

import sys,os

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

return True

def GenPswList():
"""
要求使用者輸入詞，並根據單片語合密碼，只嘗試四個單詞來組合，並限制密碼長度為20。寫的比較挫
"""
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):
"""
嘗試用密碼來解壓壓縮包
"""

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'
print 'example:test_7z_psw.py 1.7z'
sys.exit(1)

main(sys.argv[1])
