Springboot實現(xiàn)密碼的加密解密

更新時間：2017年11月15日 10:10:26 作者：卡索的意志

這篇文章主要為大家詳細介紹了Springboot實現(xiàn)密碼的加密解密，具有一定的參考價值，感興趣的小伙伴們可以參考一下

現(xiàn)今對于大多數(shù)公司來說，信息安全工作尤為重要，就像京東，阿里巴巴這樣的大公司來說，信息安全是最為重要的一個話題，舉個簡單的例子：

就像這樣的密碼公開化，很容易造成一定的信息的泄露。所以今天我們要講的就是如何來實現(xiàn)密碼的加密和解密來提高數(shù)據(jù)的安全性。

在這首先要引入springboot融合mybatis的知識，如果有這方面不懂得同學，就要首先看一看這方面的知識：

推薦大家一個比較好的博客：程序猿DD-翟永超 http://blog.didispace.com/springbootmybatis/

為了方便大家的學習，我直接將源代碼上傳：

代碼的格式如下：

完成了這一步的話首先運行一下AppTest看是否出錯，如果有錯，自己找原因，這里就不和大家討論了，寫了這么多，才要要進入正題了

本文采取的是EDS的加密解密方法，方法也很簡單，不用添加額外的jar包，只需要在UserController上做出簡單的修改就可以了：

*****UserController.java

package com.controller;

import java.security.SecureRandom;

import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESKeySpec;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.dao.UserDao;
import com.entity.User;

@Controller
public class UserController {

   @Autowired
   private UserDao userDao;
   
   @RequestMapping("/regist")
   public String regist() {
     return "regist";
   }
   
   @RequestMapping("/login")
   public String login() {
     return "login";
   }
   
   /**
    * EDS的加密解密代碼
    */
   private static final byte[] DES_KEY = { 21, 1, -110, 82, -32, -85, -128, -65 };
    @SuppressWarnings("restriction")
    public static String encryptBasedDes(String data) {
      String encryptedData = null;
      try {
        // DES算法要求有一個可信任的隨機數(shù)源
        SecureRandom sr = new SecureRandom();
        DESKeySpec deskey = new DESKeySpec(DES_KEY);
        // 創(chuàng)建一個密匙工廠，然后用它把DESKeySpec轉(zhuǎn)換成一個SecretKey對象
        SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
        SecretKey key = keyFactory.generateSecret(deskey);
        // 加密對象
        Cipher cipher = Cipher.getInstance("DES");
        cipher.init(Cipher.ENCRYPT_MODE, key, sr);
        // 加密，并把字節(jié)數(shù)組編碼成字符串
        encryptedData = new sun.misc.BASE64Encoder().encode(cipher.doFinal(data.getBytes()));
      } catch (Exception e) {
        // log.error("加密錯誤，錯誤信息：", e);
        throw new RuntimeException("加密錯誤，錯誤信息：", e);
      }
      return encryptedData;
    }
    @SuppressWarnings("restriction")
    public static String decryptBasedDes(String cryptData) {
      String decryptedData = null;
      try {
        // DES算法要求有一個可信任的隨機數(shù)源
        SecureRandom sr = new SecureRandom();
        DESKeySpec deskey = new DESKeySpec(DES_KEY);
        // 創(chuàng)建一個密匙工廠，然后用它把DESKeySpec轉(zhuǎn)換成一個SecretKey對象
        SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
        SecretKey key = keyFactory.generateSecret(deskey);
        // 解密對象
        Cipher cipher = Cipher.getInstance("DES");
        cipher.init(Cipher.DECRYPT_MODE, key, sr);
        // 把字符串進行解碼，解碼為為字節(jié)數(shù)組，并解密
        decryptedData = new String(cipher.doFinal(new sun.misc.BASE64Decoder().decodeBuffer(cryptData)));
      } catch (Exception e) {
        throw new RuntimeException("解密錯誤，錯誤信息：", e);
      }
      return decryptedData;
    }
    
   @RequestMapping("/success")
   public String success(HttpServletRequest request) {
     String username = request.getParameter("username");
     String password = request.getParameter("password");
     String s1 = encryptBasedDes(password);
     userDao.save(username, s1);
     return "success";
   }
   
   @RequestMapping("/Loginsuccess")
   public String successLogin(HttpServletRequest request) {
     String username = request.getParameter("username");
     String password = request.getParameter("password"); ///123456
     User user = userDao.findByUname(username);
       if(decryptBasedDes(user.getPassword()).equals(password)) {
         return "successLogin";
       }
       return "failure";
   }
}

此時，直接運行Apptest.java,然后在瀏覽器輸入地址：localhost:8080/regist 注冊新的賬號(我輸入的是用戶名：小明密碼：123456)，如圖
