学习加密(四)spring boot 使用RSA+AES混合加密,前后端传递参数加解密

技术标签： RSA  AES  RSA AES  混合加密  整合

 

前言:
   为了提高安全性采用了RSA,但是为了解决RSA加解密性能问题,所以采用了RSA(非对称)+AES(对称加密)方式,如果只考虑其中一种的,可以去看我前面两篇文章,专门单独写的demo,可以自行整合在项目中

大致思路:

1. 客户端启动，发送请求到服务端，服务端用RSA算法生成一对公钥和私钥，我们简称为pubkey1,prikey1，将公钥pubkey1返回给客户端。
2. 客户端拿到服务端返回的公钥pubkey1后，自己用RSA算法生成一对公钥和私钥，我们简称为pubkey2,prikey2，并将公钥pubkey2通过公钥pubkey1加密，加密之后传输给服务端。
3. 此时服务端收到客户端传输的密文，用私钥prikey1进行解密，因为数据是用公钥pubkey1加密的，通过解密就可以得到客户端生成的公钥pubkey2
4. 然后自己在生成对称加密，也就是我们的AES,其实也就是相对于我们配置中的那个16的长度的加密key,生成了这个key之后我们就用公钥pubkey2进行加密，返回给客户端，因为只有客户端有pubkey2对应的私钥prikey2，只有客户端才能解密，客户端得到数据之后，用prikey2进行解密操作，得到AES的加密key,最后就用加密key进行数据传输的加密，至此整个流程结束。

具体实践(前端请求加密,服务端解密,服务端响应加密,前端解密):

1.创建spring boot项目,导入相关依赖,
2.编写RSA加解密工具类,AES加解密工具类
3.编写自定义注解(让加解密细粒度)
4.编写自定义DecodeRequestAdvice和EncodeResponseAdvice
5.创建controller
6.创建jsp或者html,引入js(加密和解密的通用js),还有配置,配置文件
ps:因为这里没https证书,所有使用http, 考虑到前后端分离,使用json来传递数据,

    int number = random.nextInt(base.length());
81.  
    sb.append(base.charAt(number));
82.  
    }
83.  
    return sb.toString();
84.  
    }
85.  
     
86.  
    }

第五步:
 

1.  
   /**
2.  
   * 跳转RSA+AES双重加密页面
3.  
   *
4.  
   * @return
5.  
   */
6.  
    
7.  
   @RequestMapping("/test")
8.  
   public String goTest() {
9.  
   return "test";
10.  
    }
11.  
     
12.  
    /**
13.  
    * RSA+AES双重加密测试
14.  
    *
15.  
    * @return object
16.  
    */
17.  
    @RequestMapping("/testEncrypt")
18.  
    @ResponseBody
19.  
    @SecurityParameter
20.  
    public Persion testEncrypt(@RequestBody Persion info) {
21.  
    System.out.println(info.getName());
22.  
    String content = "内容";
23.  
    info.setName(content);
24.  
    return info;
25.  
    }

第六步: 其中random,js(生成一个16位数的随机字符串),是我自己定义的,其余的都可以去官方下载

后记:
     现在我要把这种混合加密方式,要整合进行到我的项目当中,到时候如果出现一些别的问题,我在更新帖,
                                                                                                                               ---没有绝对安全,只有相对安全!!!!
