Node to Node copy http://www.nncpgo.org/ 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, 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. Main difference from existing UUCP and FTN solutions, except encryption and authentication, is out-of-box offline sneakernet/floppynet, dead drops and air-gapped computers support. But online TCP daemon with full-duplex resumable data transmission exists and is built on top of Noise protocol http://noiseprotocol.org/. Where can it be useful? Occasional connection between mail servers, slow/unreliable/expensive communication links, high-volume data transfer, extreme terrestrial environments with no link, building of private, isolated MitM-resistant networks, highly secure isolated air-gap computers, network censorship bypassing, and even Reconnaissance, spying and intelligence.
