function authenticateToken(req, res, next) { const authHeader = req.header('Authorization'); const token = authHeader && authHeader.split(' ')[1]; if (token == null) return res.status(401).send("Token required");
const isValidPassword = bcrypt.compareSync(req.body.password, user.password); if (!isValidPassword) return res.status(401).send("Invalid credentials");
jwt.verify(token, process.env.SECRET_KEY, (err, user) => { if (err) return res.status(403).send("Invalid token"); req.user = user; next(); }); } This example provides a basic illustration of secure authentication and protected routes. The actual implementation would require a more detailed approach, including frontend development for user interaction. The proposed feature aims to enhance the user experience of DiskInternals Linux Reader by providing a more secure and user-friendly serial key management system. By implementing encryption, auto-renewal reminders, and a secure login system, users can manage their serial keys more effectively while ensuring their data remains protected.
