RSA(非对称)+AES(对称加密)前后台交互

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

demo下载地址:/download/baidu_38990811/10809893

大致思路:

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。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。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,

第一步:创建spring boot项目过程省略,相关依赖:
