若依SpringBoot框架前后端分离用户名密码采用RSA加密传输

因安全测试扫描到框架的登录借口使用的是明文传输，现集成jsencrypt实现用户名密 码RSA方式加密传输。（只针对漏洞进行简单修改）

---

一、前端改动

1.在前端工程utils目录新增 jsencrypt.min.js

下载链接: https://pan.baidu.com/s/13JVC9jm-Dp9PfHdDDylLCQ 提取码: y9jt

2.utils目录新增jsencrypt.js

可在线生成密钥对

import JSEncrypt from '@/utils/jsencrypt.min'

// 密钥对生成 http://web.chacuo.net/netrsakeypair

const publicKey = ''

const privateKey = ''

// 加密
export function encrypt(txt) {
  const encryptor = new JSEncrypt()
  encryptor.setPublicKey(publicKey) // 设置公钥
  return encryptor.encrypt(txt) // 对数据进行加密
}

// 解密
export function decrypt(txt) {
  const encryptor = new JSEncrypt()
  encryptor.setPrivateKey(privateKey) // 设置私钥
  return encryptor.decrypt(txt) // 对数据进行解密
}

3.登录接口调用时对用户名和密码参数加密

修改  store/modules/user.js 文件

1）导入加密方法

import { encrypt, decrypt } from '@/utils/jsencrypt'

2）对username、password参数进行加密

 // 登录
    Login({ commit }, userInfo) {
      const username = encrypt(userInfo.username.trim())
      const password = encrypt(userInfo.password)
      const code = userInfo.code
      const uuid = userInfo.uuid
      return new Promise((resolve, reject) => {
        login(username, password, code, uuid).then(res => {
          setToken(res.token)
          commit('SET_TOKEN', res.token)
          resolve()
        }).catch(error => {
          reject(error)
        })
      })
    },

二、后端改动

1.新增RsaUtils加密工具类

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.collections4.MapUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

import javax.crypto.Cipher;
import java.security.*;
import java.security.interfaces.RSAPrivateKey;
import java.security.interfaces.RSAPublicKey;
import java.security.spec.PKCS8EncodedKeySpec;
import java.security.spec.X509EncodedKeySpec;

@Component
public class RsaUtils {
    // Rsa 私钥 固定秘钥对和前端js文件中对应
    private static String publicKeyStr = "";
    private static String privateKeyStr ="";
    private static final RsaKeyPair rsaKeyPair = new RsaKeyPair();

    /**
     * 私钥解密
     *
     * @param text 待解密的文本
     * @return 解密后的文本
     */
    public static String decryptByPrivateKey(String text) throws Exception {
        return decryptByPrivateKey(privateKeyStr, text);
    }

    /**
     * 公钥解密
     *
     * @param publicKeyString 公钥
     * @param text            待解密的信息
     * @return 解密后的文本
     */
    public static String decryptByPublicKey(String publicKeyString, String text) throws Exception {
        X509EncodedKeySpec x509EncodedKeySpec = new X509EncodedKeySpec(Base64.decodeBase64(publicKeyString));
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PublicKey publicKey = keyFactory.generatePublic(x509EncodedKeySpec);
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.DECRYPT_MODE, publicKey);
        byte[] result = cipher.doFinal(Base64.decodeBase64(text));
        return new String(result);
    }

    /**
     * 私钥加密
     *
     * @param privateKeyString 私钥
     * @param text             待加密的信息
     * @return 加密后的文本
     */
    public static String encryptByPrivateKey(String privateKeyString, String text) throws Exception {
        PKCS8EncodedKeySpec pkcs8EncodedKeySpec = new PKCS8EncodedKeySpec(Base64.decodeBase64(privateKeyString));
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PrivateKey privateKey = keyFactory.generatePrivate(pkcs8EncodedKeySpec);
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.ENCRYPT_MODE, privateKey);
        byte[] result = cipher.doFinal(text.getBytes());
        return Base64.encodeBase64String(result);
    }

    /**
     * 私钥解密
     *
     * @param privateKeyString 私钥
     * @param text             待解密的文本
     * @return 解密后的文本
     */
    public static String decryptByPrivateKey(String privateKeyString, String text) throws Exception {
        PKCS8EncodedKeySpec pkcs8EncodedKeySpec5 = new PKCS8EncodedKeySpec(Base64.decodeBase64(privateKeyString));
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PrivateKey privateKey = keyFactory.generatePrivate(pkcs8EncodedKeySpec5);
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.DECRYPT_MODE, privateKey);
        byte[] result = cipher.doFinal(Base64.decodeBase64(text));
        return new String(result);
    }

    /**
     * 公钥加密
     *
     * @param publicKeyString 公钥
     * @param text            待加密的文本
     * @return 加密后的文本
     */
    public static String encryptByPublicKey(String publicKeyString, String text) throws Exception {
        X509EncodedKeySpec x509EncodedKeySpec2 = new X509EncodedKeySpec(Base64.decodeBase64(publicKeyString));
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        PublicKey publicKey = keyFactory.generatePublic(x509EncodedKeySpec2);
        Cipher cipher = Cipher.getInstance("RSA");
        cipher.init(Cipher.ENCRYPT_MODE, publicKey);
        byte[] result = cipher.doFinal(text.getBytes());
        return Base64.encodeBase64String(result);
    }

    public static String getPublicKey() {
        return publicKeyStr;
    }

    public static String getPrivateKey() {
        return privateKeyStr;
    }

    public static RsaKeyPair rsaKeyPair() {
        return rsaKeyPair;
    }

    /**
     * RSA密钥对对象
     */
    public static class RsaKeyPair {
        private String publicKey;
        private String privateKey;

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

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

        public RsaKeyPair() {

        }

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

        public String getPublicKey() {
            return publicKey;
        }

        public String getPrivateKey() {
            return privateKey;
        }
    }

2.修改登录接口 ，SysLoginService.java的login方法

增加以下代码

 try {
   username = RsaUtils.decryptByPrivateKey(username);
   password = RsaUtils.decryptByPrivateKey(password);
 } catch (Exception e) {
   throw new RuntimeException(e);
 }

三、测试

查看登录时接口参数是否加密

能够成功登录即可，修改完成。
