Secret Manager

The SecretManager class securely manages secrets and private keys, deriving a P256 key through an EIP-712 signature. The signature is hashed using SHA-256 to produce the key, ensuring security and compatibility. It extends the EventBroker class and the events are:

  • initialized: Fired when the SecretManager is successfully initialized.

Usage​

import { SecretManager } from './SecretManager';

Constructor​

new SecretManager(privKey?: string, walletClient?: WalletClient)

Parameters:

  • privKey (string,optional): The private key to use for signing transactions.
  • walletClient (WalletClient,optional): The wallet client to use for signing transactions.

Initiation​

static fromPrivKey(privKey: string): SecretManager
(or)
static fromWalletClient(walletClient: WalletClient): SecretManager

Returns:

Methods​

initialize​

async initialize(): Promise<AsyncResult<string, string>>

Initializes the SecretManager, deriving the p256 key if necessary and emitting the initialized event.

Returns:

  • AsyncResult<string, string>

generateSecret​

async generateSecret(nonce: number): Promise<AsyncResult<{ secret: string; secretHash: string }, string>>

Generates a secret and its hash using a given nonce.

Parameters:

  • nonce (number): The nonce to use for generating the secret.

Returns:

  • AsyncResult<{ secret: string; secretHash: string }, string>

getMasterPrivKey​

async getMasterPrivKey(): Promise<AsyncResult<string, string>>

Retrieves the p256 key. If it hasn't been derived yet, it will attempt to derive it from the wallet client.

Returns:

  • AsyncResult<string, string>
