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).

安装

$3

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

设置和基本用法

``javascript
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

$3

| Property | Desc. |
| -------- | --------------------------------------------------------------- |
| id | 0 = Too weak, 1 = Weak & 2 = Medium, 3 = Strong |
| value | Too weak, Weak, Medium & Strong |
| contains | lowercase, uppercase, symbol and/or number |
| length | length of the password |

| Name | Mininum Diversity | Mininum Length |
| -------- | ----------------- | -------------- |
| Too weak | 0 | 0 |
| Weak | 2 | 6 |
| Medium | 4 | 8 |
| Strong | 4 | 10 |

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

| RegEx | Desc. |
| ---------------------------------- | ------------------- |
| ^[0-9]*$ | all numbers |
| ${sensitiveWords.join('/\|')}/i | sensitive words |
| isKeyBoardContinuousChar function | keyboard continuous |

options

`javascript
[
{
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

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

敏感词，默认内置敏感词，可通过传参添加

`javascript
'admin', 'root', 'cmcc', 'cmss', 'linux'
`

$3

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

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

Medium Password RegEx used:

`
^(?=.[a-z])(?=.[A-Z])(?=.[0-9])(?=.[!@#$%^&*"'()+,-./:;<=>?[\]^_{|}~])(?=.{8,})
``

| RegEx | Desc. |
| ----------------------------------------- | ------------------------------------------------------------------- |
| ^ | 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 |
| (?=.{6,}) | Mininum of 6 characters for Weak strength |
