若依基于sm-crypto实现前后端登录密码加密

发布时间：2024年01月13日

上一节介绍了基于jsencrypt实现的密码加密解密登录功能，这次来介绍基于sm-crypto实现前后端登录密码加密，本次采用的是sm2进行的加密解密。

后端

首先从后端代码开始写起(因为公钥和私钥都是要从java代码中生成)：
首先需要引入sm-crypto的jar包，点击获取jar包，然后拷贝到下面的目录下
在这里插入图片描述
然后再pom.xml文件中引入依赖，然后刷新依赖

        <!--sm2jar包依赖-->
        <dependency>
            <groupId>com.sm2</groupId>
            <artifactId>sm2</artifactId>
            <version>1.0</version>
            <scope>system</scope>
            <systemPath>${basedir}/src/main/resources/lib/sm-crypto-0.3.2.jar</systemPath>
        </dependency>

然后就是新建一个工具类

        String[] split = str.split(",");

            if (keypair != null) {
                result[0] = keypair.getPublicKey(); //公钥
                smKeyPair.setPublicKey(keypair.getPublicKey());

        public SmKeyPair() {

        }

        public SmKeyPair(String publicKey, String privateKey) {
            this.publicKey = publicKey;
            this.privateKey = privateKey;

        }

        public void setPrivateKey(String privateKey) {
            this.privateKey = privateKey;
        }
    }

}

然后运行里面的main方法获取公钥和私钥，保存起来
在这里插入图片描述

然后再application.yml文件中加入一个配置：

#SM2解密私钥
SM_privateKey: 92b704fee9ac448ac27abfa537021ab42d0035151f01fdc03e49b0c2f5496148

最后在登录接口那里调用解密方法


    /**
     * 登录方法
     * 
     * @param loginBody 登录信息
     * @return 结果
     */
    @PostMapping("/login")
    public AjaxResult login(@RequestBody LoginBody loginBody) throws Exception
    {
        AjaxResult ajax = AjaxResult.success();
        // 生成令牌
        String token = loginService.login(loginBody.getUsername(), SM2Encryptor.decryptText(SM_privateKey, loginBody.getPassword()), loginBody.getCode(),
                loginBody.getUuid());
        ajax.put(Constants.TOKEN, token);
        return ajax;
    }

到此后端的工作就做完了

前端

前段需要先

npm i sm-crypto

在需要生成的模块，如common模块下新建一个工具类
前端代码：
在utils下新建smcrypto.js，把公钥和私钥放进来

import { sm2 } from 'sm-crypto'

const publicKey = "04b9fd451e0d0d5517069076edbc7dc83b3a885307bc8cf00185769f6818bcdf958f8dc4c8575f33dcfbe0bb18c4f651892a05a4fd923f01db2e3ad09fc4bf2878"
const privateKey = '92b704fee9ac448ac27abfa537021ab42d0035151f01fdc03e49b0c2f5496148'
const cipherMode=1

// sm2公钥加密
export function smEncryptor(password) {
  password = sm2.doEncrypt(password, publicKey, cipherMode)
  return password
}

// sm私钥解密
export function decrypt(txt) {
  return sm2.doDecrypt(txt, privateKey, cipherMode)
}

然后在登录的地方进行加密：

      const password = smEncryptor(userInfo.password)

最后就是测试效果
