Generate random password in JS with webcrypto

hash_password.js

async function hashPassword(password) {
  const passwordBuffer = new TextEncoder().encode(password);
  const hashBuffer = await crypto.subtle.digest('SHA-256', passwordBuffer);
  const hashArray = Array.from(new Uint8Array(hashBuffer));
  const hashHex = hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
  return hashHex;
}

function generateRandomPassword(length) {
  const charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  let password = '';
  for (let i = 0; i < length; i++) {
    const randomIndex = Math.floor(Math.random() * charset.length);
    password += charset[randomIndex];
  }
  return password;
}

// Exemplo de uso
const password = generateRandomPassword(16);
const hashedPassword = await hashPassword(password);
console.log(`Senha aleatória: ${password}`);
console.log(`Senha hasheada: ${hashedPassword}`);
