I'm trying to discover what cipher suites are being offered by my corporate proxy. It's set up as a man in the middle so my "secure" connections are to it, and it attempts to create a secure connection to my target.
Specifically, I'm looking to view the list of ciphers presented by the proxy in the ClientHello message of the secure connection negotiation.
I don't have the ability to run a network sniffer on outbound traffic from the proxy.
I appreciate that this is information that might be difficult to obtain since it is sent prior to the establishment of a connection, but thought that there might be a website out there for just such a need that I can't seem to find via search engine. Every other facet of the negotiation seems accessible.
The fallback plan is to expose a server running Apache and run a network sniffer on it, hit said box from the corporate network and sort through the results. There are issues that make this less than desirable.
