JS -RSA 明文加密--用户密码加密

news 2025/7/7 14:10:11

1 配置文件引入加密包 package.json

"jsencrypt": "^3.0.0-rc.1",

2 加密公钥配置

import { JSEncrypt } from 'jsencrypt'
import request from "@/utils/request";const RSA_PUBLIC_KEY = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCJVol0cJoJKA36lRJoCOe7IZNhWm/BY+zOumtVQ/uhw4+oIJQqbJ+xuAYED5VjUWGsKjqJWKAS1QuBpQNij+nUXUV1v7AB9r0ihBTwvvvVJSLOfEau6eeKEqnAW6X4bZvaexFKTxlAb7IumnlBoo8uP5bCyRt93BuseuHynoYrmwIDAQAB";//  加密
export function encryptedData(data) {// 新建JSEncrypt对象let encryptor = new JSEncrypt();// 设置公钥encryptor.setPublicKey(RSA_PUBLIC_KEY);// 加密数据return encryptor.encrypt(data);
};

3 前端请求加密传输敏感数据


import { encryptedData } from "@/utils/auth";handleSubmit(e) {const { $store } = this;e.preventDefault();this.form.validateFields(async (err, values) => {if (!err) {await $store.dispatch({type: "login/sumbitLogin",params: {userInfo: encryptedData(values.userName),password: encryptedData(values.password)}});this.$router.push({ path: "/home" });}});}

4 后端接口解密敏感数据

  final String loginName = RSAUtil.decrypt(userInfo, RSAUtil.DEFAULT_PRIVATE_KEY);
