Python 生成随机密码
亿网生成随机密码这件事情用python来干确实相当的方便，优美的string方法加上choice简直是绝配
make_password.py
###简单几行代码执行即可生成记不住的字符串###
| 1 2 3 4 5 6 7 | $ python make_passwd . py DLrw9EiT Qs4Wm84q RQwl4L2L u9g0LgwW jHPtYdyU . . . |
代码如下——注释比代码长
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | #!/usr/bin/python #–coding:utf-8–# #——————————————————————————- # Name: make_passwd # # Author: LiuSha # # Created: 28/12/2014 # Copyright: (c) WDZJ-SA 2014 #——————————————————————————- from random import choice import string def Makepass ( length = 8 , chars = string . letters + string . digits ) : return ” . join ( [ choice ( chars ) for i in range ( length ) ] ) if __name__ == ‘__main__’ : for i in range ( 10 ) : print Makepass ( ) ##下例基本上就是这个小脚本的所有工作核心了，使用random模块的choice方法取string模块生成的字符串## >>> string . letters ‘abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ’ >>> string . digits ‘0123456789’ >>> choice ( string . digits ) ‘4’ >>> choice ( string . letters ) ‘T’ ##有关生成器可参考:http://www.trustauth.cn/python/python-generator.html## |
生成一些人似乎能好记一些的密码(Qs4Wm84q这种密码似乎除了复制粘贴没有别的选择，话说前年我使用shell生成的类似的密码给ldap做默认密码，我当时公司就真有员工把这样的密码背下来了，现在想想真心是厉害~~~)。
##这样看起来是比上面的好记一点了吧，但需要提供一个字典文件##
| 1 2 3 4 5 6 7 8 | $ python make_dictpass . py 1 8 1 ipythosd $ python make_dictpass . py nahontchen chenyibfeo ipythoniue coreostche . . . |
代码如下
