springmvc 数据加密解密(2)------前端加解密

前沿

上一篇文章中，博主已经和大家介绍了如何在服务端进行加密解密，今天博主就和大家来交流一下前端如何完成与服务端加密解密。
App端的代码实现博主就不介绍了，就介绍一下前端网页的实现。

流程

根据上篇博客中提到，
1 我们得生成随机的AES秘钥
2 使用RSA公钥对AES秘钥进行加密，发送给服务端
3 服务端返回状态，可能还会返回一个临时会话号

工具

常言说得好，工欲善其事，必先利其器。为了完成上面的流程，我们先准备几个小工具，加密解密的工具如果大家看不上也可以用自己的工具哈，不强求，但我想应该找不到更好的了吧，???这些小工具在网上也可以找到，都是现成的，大家可以根据文件名称就可以搜索到。

1 生成AES的秘钥的工具

function randomString(len) {
   
   
    len = len || 32;
    var $chars = 'ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz23456789~!@#$%^&*()_+}{":?><';    /****默认去掉了容易混淆的字符oOLl,9gq,Vv,Uu,I1****/
    var maxPos = $chars.length;
    var pwd = '';
    for (i = 0; i < len; i++) {
   
   
        pwd += $chars.charAt(Math.floor(Math.random() * maxPos));
    }
    return pwd;
}
