jwt

jwt-auth

Authenticate requests with jwt, extensible claims and a specific jwks-set.

This library provides a way to decode a jwt-token with self-defined claims. Additionally one can specify a function to retrieve the JWKS. See here for further information about JWKS.

Installation

• with go-get: go get github.com/fr3dch3n/jwt-auth
• with dep: dep ensure --add github.com/fr3dch3n/jwt-auth

Usage example

Initialization

First the JWKS has to be initialized via one of the following ways:

Initialize jwk-set from json in AWS-SSM

jwt.NewAuth("/path/in/ssm", auth.FetchJwksConfigurationFromSSM)

Initialize jwk-set from local json-file

jwt.NewAuth("file/to/local/jwks.json", auth.FetchJwksConfigurationFromFS)

Authorizing requests

Then the jwt-component can be used to authenticate requests. To use specific claims, just extend the jwtgo.StandardClaims.

package handler

import (
	"fmt"
	jwtgo "github.com/dgrijalva/jwt-go"
	"github.com/fr3dch3n/jwt-auth"
	"net/http"
)

func MyAuthenticatedHandler(w http.ResponseWriter, r *http.Request) {
	authHeader := r.Header.Get("Authorization")
	token, err := jwt.DecodeToken(authHeader, &jwtgo.StandardClaims{})
	if err != nil {
	    fmt.Println(err)
	}
	fmt.Println(token)
}
