Comment (by yawning):
Another one.
* k_t used for the Session Ticket handshake HMACs is the result of 2.3
Key Derivation, instead of being the raw k_t. The obfsproxy
implementation is incorrect, but it's deployed so it wins, at least as far
as what goes into obfsclient.
{{{
log.debug("Redeeming stored session ticket.")
(masterKey, rawTicket) = storedTicket
self.deriveSecrets(masterKey)
self.circuit.downstream.write(ticket.createTicketMessage(rawTicket,
self.sendHMAC))
}}}
