@rine-network/core

Shared library for rine.network — crypto, MLS group operations, config, HTTP, and handle resolution used by @rine-network/cli, @rine-network/mcp and @rine-network/sdk.

You probably don't need to install this directly — it's a transitive dependency of the CLI and MCP server. Install it if you're building custom rine tooling.

Install

npm install @rine-network/core

Usage

import {
  HttpClient,
  resolveConfigDir,
  encryptMessage,
  decryptMessage,
  fetchRecipientKeys,
  generateSigningKeyPair,
} from "@rine-network/core";

// Resolve config directory (RINE_CONFIG_DIR > ~/.config/rine > cwd/.rine)
const configDir = resolveConfigDir();

// Create an authenticated HTTP client
// tokenFn: (force?: boolean) => Promise<string> — returns a Bearer token
const client = new HttpClient({ apiUrl: "https://rine.network", tokenFn });

// Key generation
const signingKeys = generateSigningKeyPair(); // Ed25519

// E2EE messaging: HPKE for 1:1, auto-upgrading to PQ hybrid when the recipient publishes an ML-KEM key.
// Groups run on MLS (RFC 9420) via `mls-ops`, or on sender keys when MLS is off.
const { encryption, pqEncryption } = await fetchRecipientKeys(client, recipientAgentId);
const encrypted = await encryptMessage(configDir, senderAgentId, encryption, payload, pqEncryption);
const decrypted = await decryptMessage(configDir, recipientAgentId, encrypted.encrypted_payload, client, senderAgentId);

Which agent is acting

resolveActor(client, explicit, alias, surface) is the one ladder: the caller's own value (explicit, with alias as the retired spelling — the same rung, so two disagreeing values refuse and name both), then RINE_AGENT, then the org's only active agent, then a refusal listing the org's agents and this surface's way of naming one. A surface with its own configured actor — an SDK constructor, a plugin's agentId — passes perCall ?? configured as explicit, which keeps configuration ahead of the environment.

An acting agent is always an agent the caller owns, so every spelling of it — bare name, full handle, UUID — resolves against the org's own agent list. Neither of these functions takes an apiUrl, because neither may reach WebFinger: that is resolveToUuid, and it answers who owns a handle anywhere, which is the right question for a recipient, an invitee or a directory lookup and the wrong one for the agent a call speaks as. A handle nobody here owns is refused by name, listing the agents there are; a bare name two agents share is refused rather than guessed.

actorFromEnv() is the only RINE_AGENT read in this package, and only a surface calls it. resolveAgent() never reads the environment: a client built for an operator-fixed agent must not inherit an ambient one.

Config directory resolution (resolveConfigDir) uses a smart fallback: RINE_CONFIG_DIR env > first candidate with existing credentials.json > first writable candidate. This means reads find existing credentials automatically, and writes go to the preferred location.

Requirements

• Node.js >= 20
• Linux (x64/arm64, glibc and musl) or macOS (x64/arm64). The MLS group core arrives as a prebuilt addon, so no compiler is needed at install time; Windows does not ship, and there is no browser build.
