Crate cyphernet

Cyphernet is a set of libraries for privacy-preserving networking & internet applications.

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). The library provides three main components, structured as modules:

• Network addresses (module addr), 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 (module noise) for end-to-end encrypted network communications.

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:

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