【原创】国网远程加密机认证软件开发2（认证步骤及代码）

这两天出了点问题，由于不会操作加密机，顺道学习了下加密机的硬件操作，不过已经实现了讲过网络加密机对新国网正式ESAM进行认证。

先把图片放出来吧

整个认证过程我没有对端口进行监听，也就略过了socket这部分内容，也许后续会完善进去，话不多说了，直接贴代码吧。有点乱，容我有时间整里下。

1.动态库函数调用

 [DllImport("SJJ1009forformalchip.dll")]//连接设备
        public static extern int ConnectDevice(string putIp, string putPortk, string putCTime);
 [DllImport("SJJ1009forformalchip.dll")]//关闭设备
        public static extern int CloseDevice();
 [DllImport("SJJ1009forformalchip.dll")]//身份认证
        public static extern int Meter_Formal_IdentityAuthentication(int Flag, string PutDiv, System.Text.StringBuilder OutRand, System.Text.StringBuilder OutEndata);

2.串口操作自行补脑，这里就不多解释了
