Cyphernet: privacy-preserving networking & internet applications

Build Tests Lints codecov

crates.io Docs Apache-2 licensed

This repository provides a set of libraries for privacy-preserving networking & internet applications written in rust.

The set of libraries supports mix networks (Tor, I2P, Nym), proxies, end-to-end encryption without central authorities/PKI (Noise-based encryption protocols like lightning wire protocol, NTLS etc).

Overview

The library provides three main components, structured as modules:

  • Network addresses (sub-crate cypheraddr), which allow simple use of
    • Tor, Nym, I2P and other mix networks and SOCKS proxies
    • P2P addresses with node public keys
    • May be used in a way that prevents using DNS names (outside mixnet scope).
  • Noise protocol framework (sub-crate noise-framework) for end-to-end encrypted network communications.
  • SOCKS5 client (sub-crate socks5-client) for accessing Tor and other mixnets via proxy.

All the components has a minimal set of non-optional dependencies and short compile times. For instance, SOCKS5 proxy and cyphernet addresses both have zero non-optional dependencies.

The library tries to minimize number of dependencies. Most of its functionality is available via non-default features, like:

  • noise: support for noise protocols;
  • mixnets: supports for mixnet network addresses, including tor, nym, i2p (may require additional crypto libraries for parsing public keys);
  • serde: encoding for addresses types;
  • dns: enable use of DNS names alongside IP addresses and mixnet names.

Network addresses provided by the library include the following types:

  • InetHost - IP addr or DNS name
  • HostName - IP, DNS, Tor, I2P, Nym host name (no port or proxy information)
  • NetAddr - any type of host name + port information
  • PartialAddr - any type of host name + optional port, which defaults to generic const if not provided
  • PeerAddr - any of the above addresses + node public key for authentication
  • ProxiedHost - host name + proxy (there are IP/DNS w/o proxy and with proxy)
  • ProxiedAddr - any of the above addresses + proxy (thus IP/DNS is always proxied)
