Ethereum Wallet Utils is a lightweight JavaScript library for managing Ethereum wallets. It provides functionalities for generating Ethereum wallets, encrypting and decrypting private keys, signing messages, and verifying signatures.

Features

• Generate a new Ethereum wallet (address, private key, and mnemonic)
• Encrypt and decrypt private keys securely
• Sign messages using a private key
• Verify signed messages
• Built using ethers.js

Installation

You can install the package using npm:

npm install ethereum-wallet-utils

Or using yarn:

yarn add ethereum-wallet-utils

Usage

Importing the Library

import {
    generateWallet,
    encryptPrivateKey,
    decryptPrivateKey,
    signMessage,
    verifyMessage
} from 'ethereum-wallet-utils';

Generate a New Ethereum Wallet

const wallet = generateWallet();
console.log(wallet);
// Output: { address: '0x...', privateKey: '0x...', mnemonic: '...' }

Encrypt a Private Key

const encryptedKey = await encryptPrivateKey(wallet.privateKey, 'your-secure-password');
console.log(encryptedKey);

Decrypt a Private Key

const privateKey = await decryptPrivateKey(encryptedKey, 'your-secure-password');
console.log(privateKey);

Sign a Message

const message = "Hello, Ethereum!";
const signature = await signMessage(wallet.privateKey, message);
console.log(signature);

Verify a Signed Message
