C#中SslStream测试ssl协议握手
我想知道对于服务器端的证书(只验证服务器身份),该如何操作才可以使用呢,我用了makecert自己创建了,可是后续的步骤不知道该怎么做,证书要注册到机器上?还是该怎么做呢? --------------------编程问答-------------------- 你说具体点??????帮你顶顶帖子,学习一下
--------------------编程问答-------------------- 下面是客户端进程代码,ssl协议的握手过程全靠这个sslStream.AuthenticateAsClient(serverName)函数的调用实现吗?大侠帮我解答下~

问题可能是两个
一. sslStream.AuthenticateAsClient(serverName);
SslStream.AuthenticateAsClientd的targetHost参数为客户端验证的服务端证书名称,就是服务器认证证书的“颁发给“字段。这里一定要写对,既不是CA的服务器地址,也不是类似http://ms-onlytiancai/certsrv/的字符串,也不是TcpServer的地址(实际上是TcpServer的netbios名称或dns名称,和申请服务器证书时的姓名字段是一个,必须相同)。如果填写其它字符串,在客户端验证的时候会出RemoteCertificateNameMismatch错误
二. 就是ssl服务器模式必须使用关联的私钥密码的证书 证书的格式应该为pfx格式 你可以用crt文件在控制台里面将其导成pfx格式
不知道你的证书是怎么导进去的 所以具体还要看看问题是出在哪个地方
补充:.NET技术 , C#
