python判断密码强度_python – 检查密码的强度(如何检查条件)

你好

最好的方法是使用正则表达式搜索

这是我目前使用的功能

def password_check(password):

"""

Verify the strength of 'password'

Returns a dict indicating the wrong criteria

A password is considered strong if:

8 characters length or more

1 digit or more

1 symbol or more

1 uppercase letter or more

1 lowercase letter or more

"""

# calculating the length

length_error = len(password) < 8

# searching for digits

digit_error = re.search(r"\d", password) is None

# searching for uppercase

uppercase_error = re.search(r"[A-Z]", password) is None

# searching for lowercase

lowercase_error = re.search(r"[a-z]", password) is None

# searching for symbols

symbol_error = re.search(r"[ !#$%&'()*+,-./[\\\]^_`{|}~"+r'"]', password) is None

# overall result

password_ok = not ( length_error or digit_error or uppercase_error or lowercase_error or symbol_error )

return {

'password_ok' : password_ok,

'length_error' : length_error,

'digit_error' : digit_error,

'uppercase_error' : uppercase_error,

'lowercase_error' : lowercase_error,

'symbol_error' : symbol_error,

}

编辑：

在这里提出Lukasz的建议是对特殊符号条件验证的更新

symbol_error = re.search(r"\W", password) is None
