What are the different authentication methods for APIs in Go?
In Go, common API authentication methods include Basic Auth, OAuth, JWT, and API keys. Would you like details on any specific method?
Can you explain how JWT works for API authentication?
JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: header, payload, and signature. The server generates a token after user authentication, which the client then uses for subsequent requests.
What are the advantages of using OAuth over Basic Auth?
OAuth provides better security by allowing limited access to user data without sharing credentials. It also supports token expiration and revocation, enhancing security.
How do I implement API key authentication in Go?
To implement API key authentication in Go, you can check for a specific header in incoming requests. If the key matches your stored key, grant access; otherwise, return an unauthorized response.
