jwt VS jwt

There is a special type NumericDate (https://github.com/cristalhq/jwt/blob/main/numeric_date.go) to handle this, however if you have an example where it doesn't work with golang-jwt/jwt please share it, will be happy to add a test for this (or even a fix if something is wrong :( )

Authentication is one of the most important part of almost every web application. We must ensure that every user can create, read, update and delete only data for which it's authorized. For that purpose we will use JWT (JSON Web Token). Fortunately, there are various Golang modules specialized for this. One that will be used in this guide can be found in this GitHub repo. Current latest version is v3 which can ne installed by running go get github.com/cristalhq/jwt/v3.

To add JWT authentication to our ToDo application, we'll be using the Golang-jwt library. The golang-jwt package simplifies the implementation of JWTs in Go applications, offering a suite of convenient functions that abstract away the complexities associated with token creation, verification, and management.

To create a secure Role-based authentication scheme, we need to generate a unique token when the user authenticates. This is then used to track their assigned role as they consume the availed resources. In this project we are going to use the jwt-go package to generate a JWT token that will encapsulate the user details, assigned role and permissions.

Yes. Currently maintained version is here: https://github.com/golang-jwt/jwt

Libraries used bcrypt: https://pkg.go.dev/golang.org/x/crypto/bcrypt golang-jwt: https://github.com/golang-jwt/jwt Gin (Http framework): https://github.com/gin-gonic/gin

We will implement Golang JWT authentication using a go-jwt package.

Authorization jwt

At least template-wise, I've developed pongo2 mimicking Django's template engine which I use myself for various projects. For the rest I usually stick with the standard library (net/http), golang-jwt, the Gorilla toolkit (note that it's been archived recently) and some software architecture patterns for middlewares, database abstraction, etc.

Either way, you will need to validate the signature of the JWT. You can do this with the public key and a library such as https://github.com/golang-jwt/jwt.
