3.3.5.2.4 Receive Hello + Password Message
If the Hello + Password message is received when the Authenticator is not in the "TLS Connected" state, the message MUST be silently discarded and the connection MUST be terminated.
If the Hello + Password message is received when the Authenticator is in the "TLS Connected" state, it MUST be processed with the following steps:
The local node MUST validate that the Password message has Password Length 0x0. If not, the connection MUST be terminated.
Otherwise, if the local GMC is still valid, the local node MUST:
Build a Hello message and a MyGMC message containing the local GMC chain.
Pass it to the TLS layer for processing.
Pass the message returned by the TLS layer to P2P Graphing to be sent.
Set the state to "Hello Sent".
Otherwise, if the local GMC is expired, the connection MUST be terminated.
