const bcrypt = require('bcrypt');
const jwt = require('jsonwebtoken');

async function hashPassword(plainText) {
    const saltRounds = 12;
    return await bcrypt.hash(plainText, saltRounds);
}

function generateToken(user) {
    return jwt.sign(
        { userId: user.id, email: user.email },
        process.env.JWT_SECRET,
        { expiresIn: '24h' }
