Zig Authentication API
Building an Authentication API
Zig authentication API uses JWT for secure endpoints.
Understanding JWT in Zig
JSON Web Tokens (JWT) are a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. In the context of the Zig authentication API, JWT is used to secure endpoints by ensuring that each request is authenticated.
Setting Up a Zig Project for JWT
To get started with JWT in Zig, you need to set up a Zig project. Ensure you have the latest version of Zig installed. You can initialize a new Zig project using:
This command creates a new Zig executable project with the necessary files and directory structure.
Installing Required Packages
For JWT handling, you might need to use third-party libraries. Zig's package manager can be used to include these dependencies. For instance, to include a hypothetical JWT library, modify your build.zig file:
Creating a JWT Token
Once your project is set up, you can create a JWT token. The following example demonstrates how to create a token with a payload:
Verifying a JWT Token
Verification of a JWT token is crucial to ensure that the token is valid and has not been tampered with. Here’s how you can verify a JWT token:
Securing Endpoints with JWT
To secure endpoints in your Zig application, you need to ensure that each request is accompanied by a valid JWT token. This can be done by extracting the token from the request headers and verifying it before processing the request:
