The release of Node-to-Node CoPy (NNCP) has taken place; it is a set of utilities for secure file transfer, email, and command execution in store-and-forward mode. It operates on POSIX-compliant operating systems. The utilities are written in Go and distributed under the GPLv3 license. <\/p>\n

The utilities are designed to assist in building small peer-to-peer friend-to-friend networks (a dozen nodes) with static routing for secure file transfers in fire-and-forget mode, file requests, email, and command execution requests. All transmitted packets are encrypted (end-to-end) and explicitly authenticated using known public keys of acquaintances. Onion (as in Tor) encryption is applied to all intermediate packets. Each node can act both as a client and server<\/a> utilize both push and poll behavior models. <\/p>\n

The main distinction of NNCP from UUCP and FTN (FidoNet Technology Network), aside from the aforementioned encryption and authentication, is its out-of-the-box support for Floppynet networks and computers that are physically isolated (air-gapped) from unsecured local and public networks. Another feature of NNCP is its easy integration (on par with UUCP) with current email servers<\/a>systems, such as Postfix and Exim. <\/p>\n

Potential applications of NNCP include organizing the sending\/receiving of email on devices without a persistent internet connection, file transfers under unstable network conditions, secure transmission of very large data volumes on physical media, creating data transmission networks that are resistant to MitM attacks, and bypassing network censorship and surveillance. Since the decryption key is only with the recipient, regardless of the delivery paths for the packet over the network or through physical media, a third party cannot read the contents, even if they intercept the shipment. In turn, authentication via digital signature prevents the creation of a fraudulent shipment disguised as another sender. <\/p>\n

Among the innovations in NNCP 8.8.0, compared to the previous release (version 5.0.0): <\/p>\n
