• Generate secp256k1 rotation keys and Ed25519 verification keys
• Encode/sign PLC operations with CBOR and multibase helpers
• Store DIDs, keys, and generic metadata locally

• Composer
• Extensions: curl, json

Installation

require_once 'vendor/autoload.php';

use FAIR\DID\DIDManager;
use FAIR\DID\PLC\PlcClient;
use FAIR\DID\Storage\KeyStore;

$store = new KeyStore(__DIR__ . '/keys.json');
$client = new PlcClient();
$manager = new DIDManager($store, $client);

$result = $manager->create_did(
	handle: 'example-package',
	service_endpoint: 'https://example.com/did-endpoint',
	type: 'package',
	metadata: ['owner' => 'Example Org'],
);

echo $result['did'] . PHP_EOL;
