A new Internet Draft defining the SILC Packet Protocol is available,
and has been submitted to the IETF.

o SILC Packet Protocol

  http://silcnet.org/docs/draft-riikonen-silc-pp-05.txt

  Abstract

   This memo describes a Packet Protocol used in the Secure Internet Live
   Conferencing (SILC) protocol, specified in the Secure Internet Live
   Conferencing, Protocol Specification Internet Draft [SILC1].  This
   protocol describes the packet types and packet payloads which defines
   the contents of the packets.  The protocol provides secure binary packet
   protocol that assures that the contents of the packets are secured and
   authenticated.

Changes to previous draft:

o Defined "Compressed" flag to the packet header, to indicate that
  the payload is compressed.

o Defined new SILC_PACKET_RESUME_CLIENT packet type and payload
  for it.

o Redefined the Disconnect Payload to deliver the reason of the
  disconnection as SILC status type.  Defined that human readable
  error message MAY be set as well, and is UTF-8 encoded.

o Defined that all passphrases MUST be UTF-8 encoded.

o Redefined the SILC_NOTIF_TYPE_TOPIC_SET notify type to have
  generic ID Payload as first argument, instead of using Client ID
  as first argument.

o Defined new argument <nickname> to SILC_NOTIFY_TYPE_NICK_CHANGE,
  which is the new changed nickname.

o Defined new argument <founder public key> to the
  SILC_NOTIFY_TYPE_CMODE_CHANGE and SILC_NOTIFY_TYPE_CUMODE_CHANGE
  which is used to deliver the channel founder's public key.  Defined
  that the public key received in the notify MUST be saved by routers
  and servers.

o Defined new argument <Killer's ID> to the SILC_NOTIFY_TYPE_KILLED,
  which is the killer's ID.

o Defined new SILC_NOTIFY_TYPE_ERROR and SILC_NOTIFY_TYPE_WATCH
  notify types.

o Defined that for SILC_NOTIFY_TYPE_SIGNOFF,
  SILC_NOTIFY_TYPE_SERVER_SIGNOFF, SILC_NOTIFY_TYPE_KILLED,
  SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_UMODE_CHANGE
  notify types the watcher list MUST be checked.

o Defined new SILC_MESSAGE_FLAG_REPLY and SILC_MESSAGE_FLAG_DATA
  message flags for Channel Message Payload and Private Message Payload.

o Redefined the MAC generation for the Channel Message Payload.

o Fixed errorin packet routing with primary routers from being
  clock-wise to being counter clock-wise.
