Question

我正在创建一个程序来检查密码的强度。我想阻止某人输入常用密码的能力，例如密码1＆＃39;。我也在研究密码熵，并且无法弄清楚如何将其合并到我的代码中。我是python的新手并且一直在努力，所以请原谅我。也许你们中的一些人对我能做的事情有所了解。

import re

def password():
    print ('Hello and welcome to Austin’s Password Checker!\n\nThe password must be between 6 and 12 characters\n\nConsider a capital, lowercase and number for best results!\n')

while True:
    password = input('Enter a password:')
    if 6 <= len(password) < 12:
        break
    print ('The password must be between 6 and 12 characters.\nConsider having a capital, lowercase and a number for best results!')

password_scores = {0:'Terrible', 1:'Weak', 2:'Medium', 3:'Strong'}
password_strength = dict.fromkeys(['up', 'down', 'num','spcl'], False)
if re.search(r'[A-Z]', password):
    password_strength['up'] = True
if re.search(r'[a-z]', password):
    password_strength['down'] = True
if re.search(r'[0-9]', password):
    password_strength['num'] = True
score = len([b for b in password_strength.values() if b])

print ('Password is %s' % password_scores[score])

password()

您可以将密码转储到一个集合中（用于快速查找），并使用许多在线可用字典中的一个来实际使用密码。（他们中的大多数来自泄漏，所以它应该非常有效） https://github.com/danielmiessler/SecLists/tree/master/Passwords

passwords = set(line.strip() for line in open('mostUsedPasswords.txt'))

if "matrix" in passwords:
    print("This password is frequently used")
