const { generateAddress, signMessage, verifySignature } = require('ethers-crypto');

// Generate Ethereum address const { address, privateKey } = generateAddress(); console.log('Generated Address:', address); console.log('Private Key:', privateKey);

// Sign message with private key const message = 'Hello, Ethereum!'; const signature = signMessage(message, privateKey); console.log('Message Signature:', signature);
