Usage
const { KeyManager, deriveSeedFrom } = require('@holo-host/wasm-key-manager');
const crypto = require('crypto');
const seed = crypto.randomBytes( 32 );
const hha_id = new Uint8Array([
66, 123, 133, 136, 133, 6, 247, 116,
4, 59, 43, 206, 131, 168, 123, 44,
54, 52, 3, 53, 134, 75, 137, 43,
63, 26, 216, 191, 67, 117, 38, 142
]);
// or derive seed
const seed = deriveSeedFrom( hha_id, "someone@example.com", "Passw0rd!");
const message = "Hello World";
const keys = new KeyManager( seed );
const signature = keys.sign( message );
const verified = keys.verify( message, signature );
const public_key = keys.publicKey();
const verified = KeyManager.verifyWithPublicKey( message, signature, public_key );Bundle for web
