Wireshark-dev: Re: [Wireshark-dev] Decrypting SSL in dissector

That was exactly it. Thank you!

I'm now seeing a much less critical issue:

The amp protocol starts off unencrypted, and then switches to SSL after some negotiation. When I first start wireshark (without providing a decryption key), I see the two AMP negotiation packets, and then SSLv3 packets. When I add the decryption key, the initial two handshake packets get re-decoded as "SSL Continuation Data" and I lose the unencrypted handshake information. The encrypted traffic then dissects correctly.

Is this expected? Is it possible to view both the encrypted and unencrypted portions of the protocol on the same port?

do you have a new_register_dissector("amp", ...) in the proto_register_amp()
