使用Python產生隨機密碼的樣本分享

產生隨機密碼這件事情用python來幹確實相當的方便，優美的string方法加上choice簡直是絕配
make_password.py

###簡單幾行代碼執行即可產生記不住的字串###$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...

$ python make_passwd.py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU ...

代碼如下——注釋比代碼長

產生一些人似乎能好記一些的密碼(Qs4Wm84q這種密碼似乎除了複製粘貼沒有別的選擇，話說前年我使用shell產生的類似的密碼給ldap做預設密碼，我當時公司就真有員工把這樣的密碼背下來了，現在想想真心是厲害~~~)。

##這樣看起來是比上面的好記一點了吧，但需要提供一個字典檔案##$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...$ python make_dictpass.py 1 8 1 ipythosd$ python make_dictpass.py nahontchen chenyibfeo ipythoniue coreostche ...

代碼如下

#!/usr/bin/python #--coding:utf-8--# #------------------------------------------------------------------------------- # Name: make_dictpass # # Author: LiuSha # # Created: 28/12/2014 # Copyright: (c) WDZJ-SA 2014 #------------------------------------------------------------------------------- import random import stringclass passwd(): data = open('./word.txt').read().lower() def renew(self, n, maxmem=3): self.chars = [] for i in range(n): randspot = random.randrange(len(self.data)) self.data = self.data[randspot:] + self.data[:randspot] where = -1 locate = ''.join(self.chars[-maxmem:]) while where < 0 and locate: where = self.data.find(locate) locate = locate[1:] c = self.data[where+len(locate)+1] if not c.islower(): c = random.choice(string.lowercase) self.chars.append(c) def __str__(self): return ''.join(self.chars) if __name__ == '__main__': import sys ##如果帶參數的話可以定義產生密碼的次數，長度，追溯記錄## if len(sys.argv) > 1: dopass = int(sys.argv[1]) else: dopass = 8 if len(sys.argv) > 2: length = int(sys.argv[2]) else: length = 10 if len(sys.argv) > 3: memory = int(sys.argv[3]) else: memory = 3 onepass = passwd() for i in range(dopass): onepass.renew(length,memory) print onepass

##字典檔案(可以是各種單詞的組合)## $ cat word.txt chenyi itchenyi python ipython coreos coreos.me ipython.me
