Discuss how you would implement authentication and authorization in a Go-based RESTful API.

  • Use Basic Authentication with API keys.
  • Implement OAuth 2.0 with JWT (JSON Web Tokens).
  • Utilize OpenID Connect for user authentication.
  • Use HMAC (Hash-based Message Authentication Code) for API security.
Implementing authentication and authorization in a Go-based RESTful API is a crucial aspect of security. Using OAuth 2.0 with JWT (JSON Web Tokens) is a common and secure approach. It allows for user authentication and authorization by issuing tokens, which are sent with each API request. OAuth 2.0 provides fine-grained control over access, and JWTs are self-contained, making them suitable for stateless APIs. This method ensures that only authenticated and authorized users can access protected resources, enhancing the security of your API.
