Re: RDP protocol details

lol, too funny.  I look forward to it and thanks.

That said I'm looking for where the client sends it's supported encryption
algos and methods.  I'm still learning the protocol, doesn't look like Bro
is parsing out the encryption methods or encoding methods.  Actually see
the Client security data commented out in rep-protocol.pac.

                #0xc002  -> client_security:   Client_Security_Data;

Looks like there's still more work to be done with parsing out the data?
