概述

一种检查特定密码短语的密码强度的简单方法。基于Javascript RegEx的密码强度检查器(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions).

内网在线DEMO

安装

通过程序包管理器安装

npm i @cmss/check-password-strength --save

设置和基本用法

const { passwordStrength } = require('check-password-strength')
// OR
import { passwordStrength } from 'check-password-strength'

console.log(passwordStrength('asdfasdf').value)
// Too weak (It will return Too weak if the value doesn't match the RegEx conditions)

console.log(passwordStrength('asdf1234').value)
// Weak

console.log(passwordStrength('Asd1234!').value)
// Medium

console.log(passwordStrength('A@2asdF2020!!*').value)
// Strong

其他信息

默认密码强度设置

PropertyDesc.
id0 = Too weak, 1 = Weak & 2 = Medium, 3 = Strong
valueToo weak, Weak, Medium & Strong
containslowercase, uppercase, symbol and/or number

console.log(passwordStrength('@Sdfasd2020!@#$'))
// output 
{ 
    "id": 1, 
    "value": "Strong",
    "contains": ['lowercase', 'uppercase', 'symbol', 'number'],
    "length": 15
}

默认选项

options

[
  {
    id: 0,
    value: "Too weak",
    minDiversity: 0,
    minLength: 0
  },
  {
    id: 1,
    value: "Weak",
    minDiversity: 2,
    minLength: 6
  },
  {
    id: 2,
    value: "Medium",
    minDiversity: 4,
    minLength: 8
  },
  {
    id: 3,
    value: "Strong",
    minDiversity: 4,
    minLength: 10
  } 
]

要覆盖默认选项,只需将自定义数组作为第二个参数传递:

  • id:对应于return id属性。
  • value:对应返回值属性。
  • minDiversity:介于0和4之间,对应于传递密码强度所应满足的不同条件(“小写”、“大写”、“符号”、“数字”)的最小值
  • minLength:传递密码强度时应满足的密码的最小长度

不能重写第一个元素的“minDiversity”和“minLength”参数(在方法开始时设置为0)。因此,第一个元素应该总是对应于一个“太弱”的选项。

allowedSymbols

允许的特殊字符

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

sensitiveWords

敏感词,默认内置敏感词,可通过传参添加

'admin', 'root', 'cmcc', 'cmss', 'linux'

使用

passwordStrength('myPassword', yourCustomOptions, allowedSymbols, sensitiveWords)

RegEx

Strong

 ^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#$%^&*"'()+,-./:;<=>?[\]^_`{|}~])(?=.{10,})

Medium Password RegEx used:

RegExDesc.
^The password string will start this way
(?=.*a-z)The string must contain at least 1 lowercase alphabetical character
(?=.*A-Z)The string must contain at least 1 uppercase alphabetical character
(?=.*0-9)The string must contain at least 1 numeric character
(?=.[!"#$%&\'()*+,-./:;<=>?@\\\^_`{|}~])) | The string must contain at least one special character
(?=.{10,})The string must be eight characters or longer for Strong strength
(?=.{8,})The string must be eight characters or longer for Medium strength
