)

var restrictedRoute jwt.Auth

var restrictedHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  w.Write([]byte("Welcome to the secret area!"))
})

var regularHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  w.Write([]byte("Hello, World!"))
})

func main() {
  authErr := jwt.New(&restrictedRoute, jwt.Options{
    SigningMethodString:   "RS256",
    PrivateKeyLocation:    "keys/app.rsa",     // `$ openssl genrsa -out app.rsa 2048`
    PublicKeyLocation:     "keys/app.rsa.pub", // `$ openssl rsa -in app.rsa -pubout > app.rsa.pub`
    RefreshTokenValidTime: 72 * time.Hour,
    AuthTokenValidTime:    15 * time.Minute,
    Debug:                 false,
    IsDevEnv:              true,
  })
  if authErr != nil {
    log.Println("Error initializing the JWT's!")
    log.Fatal(authErr)
  }

  http.HandleFunc("/", regularHandler)
  // this will never be available because we never issue tokens
  // see login_logout example for how to provide tokens
  http.Handle("/restricted", restrictedRoute.Handler(restrictedHandler))

Goals

It is important to understand the objective of this auth architecture. It certainly is not an applicable design for all use cases. Please read and understand the goals, below, and make changes to your own workflow to suit your specific needs.

  1. Protection of non-critical api's (e.g. not meant for financial, healthcare, gov't, etc. services)
  2. Stateless
  3. User sessions
  4. CSRF protection
  5. Web and/or mobile

Design

The design of this auth system is based around the three major components, listed below.

  1. Short-lived (minutes) JWT Auth Token
  2. Longer-lived (hours / days) JWT Refresh Token
  3. CSRF secret string

1. Short-lived (minutes) JWT Auth Token

The short-lived jwt auth token allows the user to make stateless requests to protected api endpoints. It has an expiration time of 15 minutes by default and will be refreshed by the longer-lived refresh token.

2. Longer-lived (hours/days) JWT Refresh Token

This longer-lived token will be used to update the auth tokens. These tokens have a 72 hour expiration time by default which will be updated each time an auth token is refreshed.

These refresh tokens contain an id which can be revoked by an authorized client.

3. CSRF Secret String

A CSRF secret string will be provided to each client and will be identical the CSRF secret in the auth and refresh tokens and will change each time an auth token is refreshed. These secrets will live in an "X-CSRF-Token" response header, by default, but the header key can be set as an option. These secrets will be sent along with the auth and refresh tokens on each api request.

When request are made to protected endpoint, this CSRF secret needs to be sent to the server either as a hidden form value with a name of "X-CSRF-Token", in the request header with the key of "X-CSRF-Token", or in the "Authorization" request header with a value of "Bearer " + token. This secret will be checked against the secret provided in the auth token in order to prevent CSRF attacks. It will be refreshed each time the auth token is refreshed from the refresh token.

Cookies or Bearer Tokens?

This API is setup to either use cookies (default) or bearer tokens. To use bearer tokens, set the BearerTokens option equal to true in the config settings.

When using bearer tokens, you'll need to include the auth and (optionally [the]) refresh jwt's (along with your csrf secret) in each request. Include them in the request headers. The keys can be defined in the auth options, but default to "X-Auth-Token" and "X-Refresh-Token", respectively. See the bearerTokens example for sample code of both.

Ideally, if using bearer tokens, they should be stored in a location that cannot be accessed with javascript. You want to be able to separate your csrf secret from your jwt's. If using web, I suggest using cookies. If using mobile, store these in a secure manner!

If you are using cookies, the auth and refresh jwt's will automatically be included. You only need to include the csrf token.

API

Create a new jwt middleware

var restrictedRoute jwt.Auth

JWT middleware options

type Options struct {
  SigningMethodString   string // one of "HS256", "HS384", "HS512", "RS256", "RS384", "RS512", "ES256", "ES384", "ES512"
  PrivateKeyLocation    string // only for RSA and ECDSA signing methods; only required if VerifyOnlyServer is false
  PublicKeyLocation     string // only for RSA and ECDSA signing methods
  HMACKey               []byte // only for HMAC-SHA signing method
  VerifyOnlyServer      bool // false = server can verify and issue tokens (default); true = server can only verify tokens
  BearerTokens          bool // false = server uses cookies to transport jwts (default); true = server uses request headers
  RefreshTokenValidTime time.Duration
  AuthTokenValidTime    time.Duration
  AuthTokenName         string // defaults to "AuthToken" for cookies and "X-Auth-Token" for bearer tokens
  RefreshTokenName      string // defaults to "RefreshToken" for cookies and "X-Refresh-Token" for bearer tokens
  CSRFTokenName         string // defaults to "X-CSRF-Token"
  Debug                 bool // true = more logs are shown
  IsDevEnv              bool // true = in development mode; this sets http cookies (if used) to insecure; false = production mode; this sets http cookies (if used) to secure
}

ClaimsType

type ClaimsType struct {
  // Standard claims are the standard jwt claims from the ietf standard
  // https://tools.ietf.org/html/rfc7519
  jwt.StandardClaims
  Csrf               string
  CustomClaims       map[string]interface{}
}

Note that there is a "CustomClaims" map that allows you to set whatever you want. See "IssueTokenClaims" and "GrabTokenClaims", below, for more.

Initialize new JWT middleware

authErr := jwt.New(&restrictedRoute, jwt.Options{
  SigningMethodString:   "RS256",
  PrivateKeyLocation:    "keys/app.rsa",     // `$ openssl genrsa -out app.rsa 2048`
  PublicKeyLocation:     "keys/app.rsa.pub", // `$ openssl rsa -in app.rsa -pubout > app.rsa.pub`
  RefreshTokenValidTime: 72 * time.Hour,
  AuthTokenValidTime:    15 * time.Minute,
  Debug:                 false,
  IsDevEnv:              true,
})
if authErr != nil {
  log.Println("Error initializing the JWT's!")
  log.Fatal(authErr)
}

Handle a restricted route (see below for integration with popular frameworks)

// outside of main()
var restrictedHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  csrfSecret := w.Header().Get("X-CSRF-Token")
  claims, err := restrictedRoute.GrabTokenClaims(r)
  log.Println(claims)
  
  if err != nil {
    http.Error(w, "Internal Server Error", 500)
  } else {
    templates.RenderTemplate(w, "restricted", &templates.RestrictedPage{ csrfSecret, claims.CustomClaims["Role"].(string) })
  }
})

func main() {
  ...
  http.Handle("/restricted", restrictedRoute.Handler(restrictedHandler))

  log.Println("Listening on localhost:3000")
  http.ListenAndServe("127.0.0.1:3000", nil)
}

Issue new tokens and CSRF secret (for instance, when a user provides valid login credentials)

// in a handler func
claims := jwt.ClaimsType{}
claims.StandardClaims.Id = "fakeTokenId123"
claims.CustomClaims = make(map[string]interface{})
claims.CustomClaims["Role"] = "user"

err := restrictedRoute.IssueNewTokens(w, &claims)
if err != nil {
  http.Error(w, "Internal Server Error", 500)
}

w.WriteHeader(http.StatusOK)

Note: a token Id must be provided if you'd later like the ability to revoke this token!

Get a CSRF secret from a response

// in a handler func
// note: this works because if the middleware has made it this far, the JWT middleware has written a CSRF secret to the response writer (w)
csrfSecret := w.Header().Get("X-CSRF-Token")

Get the expiration time of the refresh token, in Unix time

// in a handler func
// note: this works because if the middleware has made it this far, the JWT middleware has written this to the response writer (w)
// note: also, this won't be exact and may be a few milliseconds off from the token's actual expiry
refreshExpirationTime := w.Header().Get("Refresh-Expiry")

Get the expiration time of the auth token, in Unix time

// in a handler func
// note: this works because if the middleware has made it this far, the JWT middleware has written this to the response writer (w)
// note: also, this won't be exact and may be a few milliseconds off from the token's actual expiry
authExpirationTime := w.Header().Get("Auth-Expiry")

Get claims from a request

// in a handler func
claims, err := restrictedRoute.GrabTokenClaims(r)
log.Println(claims)

Nullify auth and refresh tokens (for instance, when a user logs out)

// in a handler func
err = restrictedRoute.NullifyTokens(w, r)
if err != nil {
  http.Error(w, "Internal Server Error", 500)
  return
}

http.Redirect(w, r, "/login", 302)

Token Id checker

A function used to check if a refresh token id has been revoked. You can either use a blacklist of revoked tokens, or a whitelist of allowed tokens. Your call. This function simply needs to return true if the token id has not been revoked. This function is run everytime an auth token is refreshed.

var restrictedRoute jwt.Auth

// create a database of refresh tokens
// map key is the jti (json token identifier)
// the val doesn't represent anything but could be used to hold "valid", "revoked", etc.
// in the real world, you would store these in your db. This is just an example.
var refreshTokens map[string]string

restrictedRoute.SetCheckTokenIdFunction(CheckRefreshToken)

func CheckRefreshToken(jti string) bool {
  return refreshTokens[jti] != ""
}

Token Id revoker

A function that adds a token id to a blacklist of revoked tokens, or revokes it from a whitelist of allowed tokens (however you'd like to do it).

var restrictedRoute jwt.Auth

// create a database of refresh tokens
// map key is the jti (json token identifier)
// the val doesn't represent anything but could be used to hold "valid", "revoked", etc.
// in the real world, you would store these in your db. This is just an example.
var refreshTokens map[string]string

restrictedRoute.SetRevokeTokenFunction(DeleteRefreshToken)

func DeleteRefreshToken(jti string) error {
  delete(refreshTokens, jti)
  return nil
}

500 error handling

Set the response to a 500 error.

var restrictedRoute jwt.Auth

restrictedRoute.SetErrorHandler(myErrorHandler)

var myErrorHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  http.Error(w, "I pitty the fool who has a 500 internal server error", 500)
  return
})

401 unauthorized handling

Set the response to a 401 unauthorized request

var restrictedRoute jwt.Auth

restrictedRoute.SetUnauthorizedHandler(MyUnauthorizedHandler)

var MyUnauthorizedHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  http.Error(w, "I pitty the fool who is unauthorized", 401)
  return
})

Integration with popular goLang web Frameworks (untested)

The architecture of this package was inspired by Secure, so I believe the integrations, below, should work. But they are untested.

    usage of log instead of myLog in auth-util.go

    Hey you used the function log instead of using myLogline 84-85 of the file auth-util.go. Due to that even if you set the options.Debug to false it keeps displaying logs. It's not a big issue but it can get quite annoying as this the concerned function is called quite often ;)

  • Echo example and odd behaviour

    Echo example and odd behaviour

    Hi,

    First of all, echo example seems kind of outdated. I need to use something like this, to make things work (with echo v3):

    e.Use(echo.WrapMiddleware(restrictedRoute.Handler))
    

    and (with echo v2):

    e.Use(standard.WrapMiddleware(restrictedRoute.Handler))
    

    Second, it seems that this thing works really weird in here. When i define routes:

    /foo
    /bar
    --- here, i'm using restrictedRoute handler as middleware ----
    /baz
    /bam
    

    Instead of "protecting" routes /baz and /bam it goes global and includes routes /foo and /bar. Why is that?

  • Refresh token being sent in each request?

    Refresh token being sent in each request?

    When using bearer tokens, you'll need to include the auth and refresh jwt's (along with your csrf secret) in each request.

    The whole point of the auth token is so that we don't need to send the refresh token each time?

  • Nice package!

    Nice package!

    Looked through the code and examples, this is a nice looking JWT package. I do have a suggestion though: rename the /src directory to /jwt so the package name is jwt. A package name of "src" is very confusing, and not idiomatic in Go. I'm looking forward to playing with this.

  • Tokens in Context

    Tokens in Context

    It would be useful to have AuthToken, RefreshToken, X-Csrf-Token and expiration in the request.Context(). This is useful if you need to send tokens in request body or do something else with tokens

        authTokenString := jwtauth.GetAuthTokenFromContext(r.Context())
        refreshTokenString := jwtauth.GetRefreshTokenFromContext(r.Context())
        csrfTokenString := jwtauth.GetCSRFTokenFromContext(r.Context())
    
        // do stuffs with tokens

  • Invalidation of cookies does not work

    Invalidation of cookies does not work

    Hi there

    In the NullifyTokens() func you want to delete / invalidate the authCookie and refreshCookie. Unfortunately this does not work if the cookie has no value for the path attribute. The browsers ignores the Set-Cookie headers and the cookies are preserved.

    Kind Regards

  • Nil pointer reference, if refreshtoken is expired or not sent with request

    Nil pointer reference, if refreshtoken is expired or not sent with request

    Hello there

    Although this is a quite unlikely scenario, the auth.Handler will panic, caused by line 412 in auth.go, if the refresh token is not sent with the request.

    Maybe error branching after calling err := auth.Process() instead of just checking for not err != nil would be a viable solution?

    Kind Regards
