这几天空闲时间就想研究一下加密，环境是web程序，通过js请求后台返回数据，我想做的事js在发送请求前将数据加密，服务端收到后解密，待服务端处理完请求后，将处理结果加密返回给客户端，客户端在解密，于是选择了RSA非对称加密，即客户端生成一对密钥，服务端生成一对密钥，两者分别将公钥给对方（页面第一次加载时请求一次服务器），但是，rsa加密，对加密的内容有长度限制，网上说可以分段加密，于是各种百度，代码都不行，而且分段加密后，服务器使用客户端的公钥无法解密了，于是换了一种思路，使用AES，但是AES要求加密解密都要使用相同的密钥，就是客户端密钥和服务器端密钥必须相同，那么问题来了，在服务器端生成密钥后，客户端js去请求获取密钥保存在本地的时候，这个过程是可以抓包的，这样别人就知道你服务器上和客户端上的密钥了，这个不安全，解决办法是客户端生成一对RSA密钥，通过js请求将公钥给服务器，服务器生成AES密钥后通过RSA公钥加密回传给客户端，这样就保证了即使抓包了，看到的数据也是rsa加密的，客户端在收到结果后，先通过RSA私钥解密，即可得到AES密钥，保存在本地session中，切勿保存在cookie中，因为抓包可以看到cookie，这样以后每次请求，服务器和客户端都将数据加密，上代码：

2.模拟客户端提交加密数据，服务端返回加密数据的服务端

3.客户端js获取到密钥后再发送请求模拟数据交互中的加密解密，可以将AES加密解密的方法封装一下，自行处理
