rift-core

Core types, identity, cryptography, and invites for the riftd P2P protocol.

Part of the riftd project — serverless P2P voice + text chat over UDP.

What's in this crate?

rift-core provides the foundational building blocks used by all other rift crates:

• Identity — Ed25519 keypair generation and management
• PeerId — Unique peer identifiers derived from public keys
• Key Exchange — X25519 for establishing shared secrets
• Noise Protocol — Session establishment helpers
• Invites — Token generation and parsing for peer discovery
• Key Derivation — HKDF-based key derivation utilities

Usage

use rift_core::{Identity, PeerId};

// Generate a new identity
let identity = Identity::generate();
let peer_id = identity.peer_id();

// Or load from disk
let identity = Identity::load_or_generate()?;
