RDFJS Sign

A set of utilities for signing RDF. :warning: Not for production use :warning:

Usage

import { DataFactory } from 'n3';
import {
  generateKeyPair, exportKey, signQuads, verifyQuads, importKey,
} from '@jeswr/rdfjs-sign';

const { quad, namedNode } = DataFactory;

const q1 = quad(namedNode('http://example.org/s'), namedNode('http://example.org/p'), namedNode('http://example.org/o1'));
const q2 = quad(namedNode('http://example.org/s'), namedNode('http://example.org/p'), namedNode('http://example.org/o2'));
const q3 = quad(namedNode('http://example.org/s'), namedNode('http://example.org/p'), namedNode('http://example.org/o3'));
const keyPair = await generateKeyPair();
const signature = await signQuads([q1, q2], keyPair.privateKey);

// true
await verifyQuads([q2, q1], signature, keyPair.publicKey);

// false
await verifyQuads([q1, q3], signature, keyPair.publicKey);

// true
await verifyQuads([q2, q1], signature, await importKey(await exportKey(keyPair.publicKey)));

CLI Usage
