Key Manager

This package houses both the abstract Key Manager interface we expose to people so that they build their own KeyManager, and an actual KeyManager ready to use for handling account-related operations.

Installation

Install through your package manager of choice:

pnpm install @pokt-foundation/pocketjs-signer

Usage

import { AbstractSigner, KeyManager } from '@pokt-foundation/pocketjs-signer'

// For the AbstractSigner, just implement it!
class MySigner extends AbstractSigner {
 // Now override the required methods...
}

// For the KeyManager, there's a few ways you can initialize it:
// 1. Create a random (new) account with the KeyManager
const randomAccount = await KeyManager.createRandom()

// 2. Use a private key you own
const account = await KeyManager.fromPrivateKey(process.env.PRIVATE_KEY);

// 3. Use a Portable-Private-Key file, stringified.
// A PPK is generated by exporting an account through the `exportPPK` method.
const ppkAccount = await KeyManager.fromPPK({ password: process.env.PASS, ppk: process.env.PPK })

// Now, you can use it!
// Get your address
const address = account.getAddress()

// Get your public key 
const publicKey = account.getPublicKey()

// Sign a message
const signedCoffee = account.sign("0xcafe")
