PKI证书签发系统（web版）

这几天没事干，学校安排小学期做一个pki证书签发系统，班上的学霸美女一组，哈哈！虽然90%的活都是我做的，但是帮帮女生也是可以得嘛！扯远了！看看效果吧！用的是ssh框架做的一个签发证书网站，有普通用户申请证书，然后管理员利用密钥库生成证书！提供用户下载这个证书安装！看看效果图吧！不过对前台不精通的我也只能做一个这样的界面了，实验室专业做前台的给我改了改！看看效果吧！

效果差不多是这样的。
看看代码怎么实现的吧！首先是数据库，利用mysql数据库，
创建一个名字为pki的数据库！如下图是数据库表的基本字段
用户表和证书基本信息表
用户表

证书表

下面就是证书实现的的重点方法了！由于代码较多，就跳几个重要的贴上来吧！
首先是证书的action
