网站设计方案图互联网广告优化

一.VUE3代码实现

1.安装依赖

 npm install --save sm-crypto

2.导入sm2

 const sm2 = require('sm-crypto').sm2

3.定义公钥私钥

var privateKey = "私钥";//解密使用
var publicKey  = "公钥";//加密使用

4.设置加密模式

//cipherMode [加密模式 C1C3C2:1, C1C2C3:0]const cipherMode = 1;//默认是1

5.加密

 
页面代码直接@click绑定getphone即可单击实现data() {return {copyphone：'',phone:'123545687',}}
methods: {getphone（）{const sm2 = require('sm-crypto').sm2;var publicKey  = "公钥";//加密使用var encrText = 需要加密的字段;//例如var enxrText = this.phone;const cipherMode = 1;let decryptData = sm2.doEncrypt(encrText, publicKey, cipherMode) // 加密结果return '04' + decryptData;//04可不要具体看后端要求}}

6.解密

 页面代码直接@click绑定getphone即可单击实现data() {return {copyphone：'',}}
methods: {getphone（）{const sm2 = require('sm-crypto').sm2;//var privateKey = "私钥";var encrText = 需要解密的字段; //有04要截 var encrText = val.substring(2);val是后台传过来的加密字段，将‘04’截取掉const cipherMode = 1let decryptData = sm2.doDecrypt(encrText, privateKey, cipherMode) // 解密结果return decryptData ;this.copyphone = decryptData;//赋值方便处理console.log(this.copyphone);//直接打印出来看是否实现}}

二、springboot代码实现

1.导入maven依赖

        <dependency><groupId>org.bouncycastle</groupId><artifactId>bcprov-jdk15on</artifactId><version>1.70</version></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.9</version></dependency>

2.代码实现
