如何测试与服务器的Milo客户端连接是否实际使用加密?

[英]How can I test if a Milo client connection to a server is actually using encryption?

When using Eclipse Milo as a client, I want to test, after the connection has been established, if the connection is actually using encryption. 当使用Eclipse Milo作为客户端时,我想在建立连接后测试该连接是否实际上在使用加密。

What is the best approach to do so? 这样做的最佳方法是什么?

To truly verify you would need to look at Wireshark. 要真正进行验证,您需要查看Wireshark。 Wireshark understands OPC-UA, so after configuring it to interpret the port of the server you're connected to as UA, you'll see all the messages show up as "UA Secure Conversation Message" or something along those lines. Wireshark理解OPC-UA,因此在将其配置为将您连接的服务器的端口解释为UA之后,您会看到所有消息都显示为“ UA安全对话消息”或类似的内容。 When encryption is not used you can actually see the type, full structure, and content of every message between client and server. 当不使用加密时,您实际上可以看到客户端和服务器之间每条消息的类型,完整结构和内容。
