c# – ssl证书代码中的异常

作者:互联网

我使用sslStream创建了一个客户端服务器套接字连接,但是当代码到达我在Internet上搜索过的AuthenticateAsServer行时,服务器上有一个异常,但我找不到一个好的答案.
我在我的项目中制作了.pfx测试文件,并为它制作了一个简单的密码.我不知道问题是否来自文件.

异常是在行:sslStream.AuthenticateAsServer(certificate);

基本的例外是:对sspi的调用失败

内部异常是:客户端和服务器无法通信,因为它们不具备通用算法

服务器有点长,我添加了异常发生的代码部分和所有客户端代码:

这是服务器:

 public void AcceptCallBack(IAsyncResult ar) 
        {
        //    clients.Add(new myClient(server.EndAccept(ar)));
        //    try
       //     {
                myClient c = new myClient();

               // Socket handle = (Socket)ar.AsyncState;
                TcpListener handle = (TcpListener)ar.AsyncState;
                byte[] buff=new byte[2048] ;
               // Socket hand = handle.EndAccept(out buff,ar);
                TcpClient hand = handle.EndAcceptTcpClient(ar);
                dowork.Set();
                c.tcp = hand;
                clients.Add(c);
               // hand.BeginReceive(c.buffer, 0, c.buffer.Length, SocketFlags.None, new AsyncCallback(receiveIDCallBack), c);
                using (SslStream sslStream = new SslStream(hand.GetStream()))
                {
                    sslStream.AuthenticateAsServer(certificate);
                    // ... Send and read data over the stream
                    sslStream.BeginWrite(buff,0,buff.Length,new AsyncCallback(sendCallBack),c);
                    count++;
                    sslStream.BeginRead(c.buffer,0,c.buffer.Length,new AsyncCallback(receiveIDCallBack),c);
                }
       //     }
         //   catch(Exception)
          //  {

         //   }
        }//end of acceptcallback function

这可能是vs或Windows选项中生成的证书文件的问题吗?

我在互联网上搜索了一下,我认为应该存在我用于证书文件的算法不匹配的可能性以及Windows 8.1可以理解的内容.我真的不知道….

vs让我为我的证书制作的算法是“sha256RSA”和“sha1RSA”
谢谢你的帮助

解决方法:

i made the .pfx testfile in my project

那是一面大红旗.在不了解您使用的工具的情况下,最好的猜测是您创建了签名证书.它不适合密钥交换.此blog post涵盖的故障模式.

在不了解您的操作系统的情况下,我不得不猜测您使用的是Linux.在这种情况下this question应该是有帮助的.如果这是一个错误的猜测,那么通过谷歌搜索“创建自签名的ssl证书,添加适当的关键字来选择您的操作系统和/或工具链来帮助自己.
