最近由于项目需要做一个url传参，并在页面显示参数内容的需求，这样就会遇到一个url地址可能会被假冒，
并传递非法内容显示在页面的尴尬情况
比如xxx.shtml?server=xxx是坏人&name=xxxoo
这个url被人篡改胡乱发出去，追究责任还是要追究到网站负责人的。
于是想起来用加密url参数的方法，最先想到的是用base64加密参数，但是这样有点钱的知识的人，在js里面看
到如何解密，就知道怎么加密了，url还是能胡乱伪造后来仔细思量加密，非对称加密，一闪而过，在网上找了
一下相关资料，发现有javascript版本的RSA非对称加密，大概看下如何使用，最终发现可用。
废话完毕，直接上代码：
