我想向客户展示我的客户端/服务器应用程序正在使用具有相互身份验证的安全连接。
我的服务器应用程序是使用 C# 实现的，客户端使用 C 和 OpenSSL。他们可以互相交谈并且工作正常。我正在尝试使用以下两种解决方案进行演示，但我对结果不满意。
使用监控连接SSLDump :
The output is listed below, seems to be nothing wrong with it, but not sure about that. Please help me with this.
使用Wireshark 和 监控连接Unsniff ,
A network analysis tool, that can give me some kind of high level analysis result, could be very helpful with my demonstration. But when I watch the connection with these two tools, they all show me that the protocol is TCP, and I want they show me that protocol of the connection is SSL/TLS.
有什么想法吗？
Output from SSLDump:
fan@ubuntu:~/Desktop$ sudo ssldump -i eth0 port 9527 and host fan

最佳答案
这看起来像是与客户端和服务器证书交换的正常 SSL/TLS 协商。但是至少客户端和服务器看起来像是在运行 TLS 1.0。根据您的安全要求，使用 TLS 1.2 和更安全的 block 密码可能会更好。
