      const validateInput = (schema) => (req, res, next) => {
        const { error } = schema.validate(req.body);
        if (error) {
          return res.status(400).json({ 
            error: error.details[0].message 
          });
        }
        next();
      };

      const hashPassword = async (password) => {
        return await bcrypt.hash(password, saltRounds);
      };

      // JWT token verification
      const verifyToken = (req, res, next) => {
        const token = req.headers.authorization?.split(' ')[1];
        if (!token) {
          return res.status(401).json({ error: 'Access denied' });
        }

        try {
          const decoded = jwt.verify(token, process.env.JWT_SECRET);
          req.user = decoded;
          next();
        } catch (error) {
          res.status(400).json({ error: 'Invalid token' });
        }
