Random password

对市面上的random password管理器不是很放心，还是自己写一个来的安心。

生成器：

#!/usr/bin/python
import random,sys

SPECIAL='~_+`-=!@#$%^&*(){}|\][:;<>,.?/'
PRINT='asdfghjklqwertyuiopzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM1234567890'

def get_next(s):
    return s[random.randrange(0, len(s))]

length=15
if (len(sys.argv) ==2): length=int(sys.argv[1])
p=''
for i in range(length):
    if random.random() > 0.8:
        p += get_next(SPECIAL)
    else:
        p += get_next(PRINT)
print ''
print p
print ''
