Description

TLS/SSL
At this moment moloch shows only TLS version, negotiated cipher and some certificate data.

Previous task version
https://redmine.openinfosecfoundation.org/issues/2939

The Illustrated TLS Connection
https://tls.ulfheim.net/

For Suricata TLS plugin I suggest to include this values in the moloch screen

Client Hello - Cipher Suites proposals, Compression Methods, Extension - Supported Groups, Extension - EC Point Formats, Extension - Signature Algorithms, Extension - Renegotiation Info, Diffie-Hellman server parameters proposals

Server Hello - Cipher Suite, Compression Method, Diffie-Hellman server parameters (signal-Screenshot_20190327_212101.png)

Server Key Exchange - Curve Info, Public Key, Signature

I will try to find similar illustrated guide for IKEvX and SSH and describe similar proposals for IKEv1, IKEv2, IKEv3 and SSH.

I also uploaded my signatures for TLS inspection.

Phrase
alert tls any !10050:10051

Suricata code location - Moloch, Suricata plugins

I will be glad to cooperate on this projects

https://redmine.openinfosecfoundation.org/issues/2962

But, I can't locate the right part of the code in the repository (means Moloch and Suricata plugins)

Can you give me a contact to a responsible person, who will help me to
find the right part of Suricata plugin and Moloch code?

Thank you very much

May be Pierre Chifflier (pollux on #suricata IRC) could help with some guidance with respect to the Suricata code.
