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
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
package com.ruoyi.common.utils.sm2Encrypt;

}
public void setPublicKey(String publicKey) {
this.publicKey = publicKey;
}
public String getPrivateKey() {
return 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
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)
