Node Zero — Cryptographic Mesh Node

What it is

Ed25519-equivalent keypair generation entirely in the browser via WebCrypto. Cryptographic Mesh Node is a core component of the P31 Labs sovereign cognitive infrastructure stack — built to run offline, deployed to the edge, and designed without dark patterns.

Pure TypeScript compiled to a single-file HTML. WebCrypto SubtleCrypto handles all key operations. IndexedDB stores only encrypted blobs — the plaintext key is only in-memory during active use.

Core features

Ed25519-equivalent keypair generation entirely in the browser via WebCrypto

Encrypted IndexedDB vault: private key never touches plaintext storage

Channel management: create, rotate, and revoke named communication channels

Transport adapters: WebSocket, BroadcastChannel, and localhost HTTP

Identity export: portable encrypted bundle for cold storage

How to use

1Generate a keypair on first open — public key displays as a QR code for sharing

2Create a channel: name it, choose a transport, and share the channel ID

3Export your identity bundle: set a passphrase, download the encrypted JSON
