前端加密方案
- 参考文档 https://cryptojs.gitbook.io/docs/
- 使用AES对用户密码进行加密(支持可配置的加密秘钥进行加解密)
安装依赖包
引入crypto-js
bash
yarn add crypto-js
node示例
js
/**
* @see https://cryptojs.gitbook.io/docs/
*/
const CryptoJS = require('crypto-js')
var text = 'Message'
var key = 'xxxxxx'
var encrypted = CryptoJS.AES.encrypt(text, key).toString()
var decrypted = CryptoJS.AES.decrypt(encrypted, key).toString(CryptoJS.enc.Utf8)
console.log('text', text)
console.log('key', key)
console.log('AES-encrypted', encrypted)
console.log('AES-decrypted', decrypted)
输出结果
bash
text Message
key xxxxxx
AES-encrypted U2FsdGVkX18mFLck5J77h97l/m1gWKBIuXEFHdTphvo=
AES-decrypted Message

vue示例
为方便多处调用,实际使用中把加密解密方法写在一个文件中用于统一维护和使用
封装工具
cryptojs.ts
ts
/**
* @see https://cryptojs.gitbook.io/docs/
*/
import CryptoJS from 'crypto-js'
// AES秘钥,与后端约定保持一致
const keyWords = 'xxxxxx'
// 加密方法,登录和修改密码使用
export const encrypt = (pwd: string) :string => CryptoJS.AES.encrypt(pwd, keyWords).toString()
// 解密方法,验证旧密码使用
export const decrypt = (pwd: string) :string => CryptoJS.AES.decrypt(pwd, keyWords).toString(CryptoJS.enc.Utf8)
代码示例
vue
<template>
<input type="text" v-model="text" />
<p>AES加密:{{encrypt(text)}}</p>
<p>AES解密:{{decrypt(encrypt(text))}}</p>
</template>
<script setup lang="ts">
import { ref } from 'vue'
import { encrypt, decrypt } from './cryptojs' // 加密解密方法
const text = ref('Message')
</script>
