A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](http://self-issued.info/docs/draft-jones-json-web-token.html)
**NOTICE:** We recently introduced a breaking change in the API. Please refer to [VERSION_HISTORY.md](VERSION_HISTORY.md) for details.
## What the heck is a JWT?
In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way.
The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used.
The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
## What's in the box?
This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are RSA256 and HMAC SHA256, though hooks are present for adding your own.
## Parse and Verify
Parsing and verifying tokens is pretty straight forward. You pass in the token and a function for looking up the key. This is done as a callback since you may need to parse the token to find out what signing method and key was used.
```go
token, err := jwt.Parse(myToken, func(token *jwt.Token) (interface{}, error) {
return myLookupKey(token.Header["kid"])
})
if err == nil && token.Valid {
deliverGoodness("!")
} else {
deliverUtterRejection(":(")
}
```
## Create a token
```go
// Create the token
token := jwt.New(jwt.SigningMethodHS256)
// Set some claims
token.Claims["foo"] = "bar"
token.Claims["exp"] = time.Now().Add(time.Hour * 72).Unix()
// Sign and get the complete encoded token as a string
tokenString, err := token.SignedString(mySigningKey)
```
## Project Status & Versioning
This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
## More
Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. For a more http centric example, see [this gist](https://gist.github.com/cryptix/45c33ecf0ae54828e63b).

## `jwt-go` Version History
#### 2.2.0
* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`. Result will now be the parsed token and an error, instead of a panic.
#### 2.1.0
Backwards compatible API change that was missed in 2.0.0.
* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
#### 2.0.0
There were two major reasons for breaking backwards compatibility with this update. The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change.
The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
* **Compatibility Breaking Changes**
* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
* `KeyFunc` now returns `interface{}` instead of `[]byte`
* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodHS256`
* Added public package global `SigningMethodHS384`
* Added public package global `SigningMethodHS512`
* Renamed type `SigningMethodRS256` to `SigningMethodRSA`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodRS256`
* Added public package global `SigningMethodRS384`
* Added public package global `SigningMethodRS512`
* Moved sample private key for HMAC tests from an inline value to a file on disk. Value is unchanged.
* Refactored the RSA implementation to be easier to read
* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
#### 1.0.2
* Fixed bug in parsing public keys from certificates
* Added more tests around the parsing of keys for RS256
* Code refactoring in RS256 implementation. No functional changes
#### 1.0.1
* Fixed panic if RS256 signing method was passed an invalid key
#### 1.0.0
* First versioned release
* API stabilized
* Supports creating, signing, parsing, and validating JWT tokens
* Supports RS256 and HS256 signing methods

# jwt
[![GoDoc](https://godoc.org/github.com/thermokarst/jwt?status.svg)](https://godoc.org/github.com/thermokarst/jwt)
A simple, opinionated Go net/http middleware for integrating JSON Web Tokens into
your application:
```go
package main
import (
"errors"
"fmt"
"net/http"
"time"
"github.com/thermokarst/jwt"
)
func protectMe(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "secured")
}
func main() {
var authFunc = func(email string, password string) error {
// Hard-code a user --- this could easily be a database call, etc.
if email != "test" || password != "test" {
return errors.New("invalid credentials")
}
return nil
}
var claimsFunc = func(userId string) (map[string]interface{}, error) {
currentTime := time.Now()
return map[string]interface{}{
"iat": currentTime.Unix(),
"exp": currentTime.Add(time.Minute * 60 * 24).Unix(),
"sub": userId,
}, nil
}
var verifyClaimsFunc = func(claims []byte) error {
currentTime := time.Now()
var c struct {
Exp int64
Iat int64
Sub string
}
err := json.Unmarshal(claims, &c)
if err != nil {
return err
}
if currentTime.After(time.Unix(c.Exp, 0)) {
return errors.New("this token has expired!")
}
if c.Sub != "test" {
return errors.New("who are you??!")
}
return nil
}
config := &jwt.Config{
Secret: "password",
Auth: authFunc,
Claims: claimsFunc,
}
j, err := jwt.New(config)
if err != nil {
panic(err)
}
protect := http.HandlerFunc(protectMe)
http.Handle("/authenticate", j.GenerateToken())
http.Handle("/secure", j.Secure(protect, verifyClaimsFunc))
http.ListenAndServe(":8080", nil)
}
```
# Installation
$ go get github.com/thermokarst/jwt
# Usage
**This is a work in progress**
Create a new instance of the middleware by passing in a configuration for your
app. The config includes a shared secret (this middleware only builds HS256
tokens), a function for authenticating user, and a function for generating a
user's claims. The idea here is to be dead-simple for someone to drop this into
a project and hit the ground running.
```go
config := &jwt.Config{
Secret: "password",
Auth: authFunc, // func(string, string) error
Claims: claimsFunc, // func(string) (map[string]interface{})
}
j, err := jwt.New(config)
```
Once the middleware is instantiated, create a route for users to generate a JWT
at.
```go
http.Handle("/authenticate", j.GenerateToken())
```
The auth function takes two arguments (the identity, and the authorization
key), POSTed as a JSON-encoded body:
{"email":"user@example.com","password":"mypassword"}
These fields are static for now, but will be customizable in a later release.
The claims are generated using the claims function provided in the
configuration. This function is only run if the auth function verifies the
user's identity, then the user's unique identifier (primary key id, UUID,
email, whatever you want) is passed as a string to the claims function. Your
function should return a `map[string]interface{}` with the desired claimset.
Routes are "secured" by calling the `Secure(http.Handler, jwt.VerifyClaimsFunc)`
handler:
```go
http.Handle("/secureendpoint", j.Secure(someHandler, verifyClaimsFunc))
```
The claims verification function is called after the token has been parsed and
validated: this is where you control how your application handles the claims
contained within the JWT.
# Motivation
This work was prepared for a crypto/security class at the University of Alaska
Fairbanks. I hope to use this in some of my projects, but please proceed with
caution if you adopt this for your own work. As well, the API is still quite
unstable, so be prepared for handling any changes.
# Tests
$ go test
