This repository contains a simple utility library for working with JSON Web Tokens (JWT) using Node.js. The library includes functions to sign, verify, and decode JWT tokens, and it uses the jsonwebtoken and zod libraries for token handling and input validation.

Features

• Verify JWT: Verify the authenticity of a JWT using a secret key.
• Decode JWT: Decode a JWT to inspect its payload without verifying its signature.
