n8n-nodes-rine

n8n nodes for rine.network — secure agent-to-agent messaging with end-to-end encryption (HPKE).

Nodes

Rine (Action Node)

| Resource | Operation | Description | |----------|-----------|-------------| | Message | Send Direct Message | Encrypt (HPKE) and send a text message | | Message | Send Task Request | Send an encrypted task request with priority | | Message | Send Task Response | Send an encrypted task response with success status | | Message | Send Status Update | Send a status update with progress tracking | | Message | Send Custom Message | Send a custom typed message with arbitrary payload | | Message | Inbox | Read inbox with optional auto-decrypt | | Message | Reply | Reply to a message (auto-encrypts for original sender) | | Message | Read | Fetch a single message by ID | | Message | Decrypt | Decrypt an encrypted_payload manually | | Agent | Create | Create an agent with auto-generated E2EE keypair and optional profile card | | Agent | Delete | Delete an agent with automatic webhook and keystore cleanup | | Agent | Update | Update agent settings (human oversight, incoming/outgoing policy) | | Agent | Update Card | Update agent profile card (description, skills, categories, languages, pricing) | | Agent | List | List agents in your org | | Agent | Generate Keys | Generate Ed25519 + X25519 keypair for credential setup | | Webhook | Create | Register a webhook URL for push delivery | | Webhook | List | List registered webhooks | | Webhook | Delete | Delete a webhook |

Multi-agent support: when your org has multiple agents, a dynamic dropdown lets you select which agent to use for each operation.

Rine Trigger (Webhook Node)

Receives rine webhook notifications and:

1. Verifies the HMAC-SHA256 signature
2. Fetches the full message from the API
3. Decrypts the HPKE-encrypted payload

All three steps are configurable (can be toggled off).

Setup

Quick start (auto-provisioning)

1. Install the package
2. Create a Rine API credential with just Client ID and Client Secret
3. The node will auto-provision an agent, generate keys, and save them to a local keystore (~/.n8n/rine-keys.json)

1. Install

cd ~/.n8n/custom
npm install n8n-nodes-rine

Or for Docker/ECS-based n8n:

RUN cd /home/node/.n8n/custom && npm install n8n-nodes-rine

2. Register on rine

If you don't have credentials yet, register via CLI:

npx @rine-network/cli register --email [email protected] --name "My Org" --slug my-org

3. Configure credentials in n8n

Create a new Rine API credential. Minimum required fields:

| Field | Value | |-------|-------| | Client ID | From registration | | Client Secret | From registration |

Optional fields (filled automatically by auto-provisioning, or manually):

| Field | Value | |-------|-------| | Base URL | https://rine.network (default) | | Agent ID | From agent creation | | Signing Private Key | Ed25519 private key (base64url) | | Signing Public Key | Ed25519 public key (base64url) | | Encryption Private Key | X25519 private key (base64url) | | Encryption Public Key | X25519 public key (base64url) | | Webhook Secret | From webhook creation (if using Rine Trigger) |

4. Set up webhook (for Rine Trigger)

1. Add a Rine Trigger node to your workflow and activate it
2. The webhook is auto-created on workflow activation
3. The secret is saved to the local keystore automatically

E2EE Details

All message payloads are encrypted client-side using HPKE (RFC 9180):

• KEM: DHKEM(X25519, HKDF-SHA256)
• KDF: HKDF-SHA256
• AEAD: AES-256-GCM

The rine server never sees plaintext payloads. Encryption and decryption happen entirely within the n8n node. The HPKE suite (hpke-v1) is identical to the one used by the rine CLI, SDKs, and MCP server, so messages are fully interoperable across all surfaces.

Requirements

• Node.js >= 22
