   1 NNCP (Node to Node copy) is a collection of utilities simplifying
   2 secure store-and-forward files and mail exchanging.

   6 This utilities are intended to help build up small size (dozens of
   7 nodes) ad-hoc @url{https://en.wikipedia.org/wiki/Friend-to-friend,
   8 friend-to-friend} (F2F) statically routed
   9 @url{https://en.wikipedia.org/wiki/Darknet, darknet} networks for
  10 fire-and-forget secure reliable files, file requests and Internet mail
  11 transmission. All packets are integrity checked,
  12 @url{https://en.wikipedia.org/wiki/End-to-end_encryption, end-to-end}
  13 encrypted, explicitly authenticated by known participants public keys.
  14 @url{https://en.wikipedia.org/wiki/Onion_routing, Onion encryption} is
  15 applied to relayed packets. Each node acts both as a client and server,
  16 can use push and poll behaviour model.

  18 Out-of-box offline @url{https://en.wikipedia.org/wiki/Sneakernet,
  19 sneakernet/floppynet}, @url{https://en.wikipedia.org/wiki/Dead_drop,
  20 dead drops} and @url{https://en.wikipedia.org/wiki/Air_gap_(networking),
  21 air-gapped} computers support. But online TCP daemon with full-duplex
  22 resumable data transmission exists.

  24 Look for possible @ref{Use cases, use cases}!

  26 NNCP is @url{https://www.gnu.org/philosophy/pragmatic.html, copylefted}

  28 licenced under @url{https://www.gnu.org/licenses/gpl-3.0.html, GNU GPLv3+}.
  29 It should work on all @url{https://en.wikipedia.org/wiki/POSIX,
  30 POSIX}-compatible systems. Easy @ref{Integration, integration} with existing
  31 @url{https://en.wikipedia.org/wiki/SMTP, SMTP} servers. Single
  32 @url{http://yaml.org/, YAML} configuration file.

  34 Why create yet another store-and-forward solution when UUCP, FTN and
  35 even SMTP exists? Look in @ref{Comparison, comparison} section!
  36 Simplicity, cryptographic security, sneakernet compatibility and easy
  37 integration with current SMTP servers are the reasons.
