Hello everyone,

Is there anyway to decrypt SSL? We are tapping into traffic after leaving our proxy and we are trying to to decrypt https requests so we can see the request and response properly.

Thank you Russel for the quick response. We are intercepting traffic and we are using our own cert. So I was wondering if there is a place where i can configure the private key to decrypt traffic.... similar to Wireshark.

Depending on how your proxy is set up you *may* be able to inspect traffic there.  I say *may* because it will only work if your proxy is already Man In The Middle all your web traffic.

Moloch will extract certificate names which we find useful.

This may not be a current feature of Moloch, but it is possible to passively inspect SSL/TLS traffic if encrypted with a known private key and the session does not use Diffie-Hellman ephemeral keys, which uses symmetric "session keys" to provide forward secrecy if the asymmetric private key is ever compromised.
