I am pleased to announce NNCP 2.0 release availability!

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

This utilities are intended to help build up small size (dozens of
nodes) ad-hoc friend-to-friend (F2F) statically routed darknet networks
for fire-and-forget secure reliable files, file requests and Internet
mail transmission. All packets are integrity checked, end-to-end
encrypted (E2EE), explicitly authenticated by known participants public
keys. Onion encryption is applied to relayed packets. Each node acts
both as a client and server, can use push and poll behaviour model.

Out-of-box offline sneakernet/floppynet, dead drops, sequential and
append-only CD-ROM/tape storages, air-gapped computers support. But
online TCP daemon with full-duplex resumable data transmission exists.

------------------------ >8 ------------------------

The main improvements for that release are:

* *Incompatible* encrypted/eblob packet format changes. Older versions
  are not supported.
* Twofish encryption algorithm is replaced with ChaCha20. It is much
  more faster. One cryptographic primitive less.
* HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
  another cryptographic primitive less (assuming that BLAKE2X is nearly
  identical to BLAKE2).
