Building Secure REST APIs in Go: User Authentication with JWT

Building a REST API is only the first step; securing it against unauthorized access is critical for any production-ready application. This text-based course guides you through the essential process of protecting your Go backend services. You will read clear explanations, study structured code snippets, and learn how to handle user registration, securely store passwords, and issue JSON Web Tokens (JWT) to manage user sessions safely. What you'll learn: - Understand the core concepts of REST API security, session management, and token-based authentication. - Implement secure password hashing using bcrypt to safely store user credentials. - Generate and validate JSON Web Tokens (JWT) for stateless user authentication. - Create custom middleware in Go to protect specific API endpoints and restrict access. - Handle user registration and login flows with structured input validation. - Apply modern Go practices, including context propagation and structured error handling, for clean backend architecture. The course starts with essential security terminology and foundational concepts of web authentication. You will then progress step-by-step through writing clean, modular Go code to handle user registration, secure credential storage, token generation, and route protection. This course is designed for beginner Go developers and backend enthusiasts who want to learn security fundamentals. No advanced cryptography experience is required; a basic understanding of Go syntax and REST principles is all you need to start. Start reading today to build secure and reliable APIs with Go.
