-**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/).  As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected.  There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API.  In the short term, please make sure your implementation verifies the `alg` is what you expect.

+**NEW VERSION COMING:** There have been a lot of improvements suggested since the version 3.0.0 released in 2016. I'm working now on cutting two different releases: 3.2.0 will contain any non-breaking changes or enhancements. 4.0.0 will follow shortly which will include breaking changes. See the 4.0.0 milestone to get an idea of what's coming. If you have other ideas, or would like to participate in 4.0.0, now's the time. If you depend on this library and don't want to be interrupted, I recommend you use your dependency mangement tool to pin to version 3.

+**SECURITY NOTICE:** Some older versions of Go have a security issue in the cryotp/elliptic. Recommendation is to upgrade to at least 1.8.3. See issue #216 for more detail.

 ## What the heck is a JWT?

+JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
+
 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.
@ -16,37 +25,13 @@ The part in the middle is the interesting bit.  It's called the Claims and conta

 This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.

-## Parse and Verify
+## Examples

-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.
+See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:

-```go
-	token, err := jwt.Parse(myToken, func(token *jwt.Token) (interface{}, error) {
-		// Don't forget to validate the alg is what you expect:
-		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
-			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
-		}
-		return myLookupKey(token.Header["kid"]), nil
-	})
-
-	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)
-```

 ## Extensions

 Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go

+## Compliance
+
+This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences:
+
+* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
+
 ## 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).

-While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users.  You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`.  It will do the right thing WRT semantic versioning.

+
+**BREAKING CHANGES:*** 
+* Version 3.0.0 includes _a lot_ of changes from the 2.x line, including a few that break the API.  We've tried to break as few things as possible, so there should just be a few type signature changes.  A full list of breaking changes is available in `VERSION_HISTORY.md`.  See `MIGRATION_GUIDE.md` for more information on updating your code.

 ## Usage Tips

@ -81,18 +75,26 @@ Symmetric signing methods, such as HSA, use only a single secret. This is probab

 Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.

+### Signing Methods and Key Types
+
+Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
+
+* The [HMAC signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
+* The [RSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
+* The [ECDSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
+
 ### JWT and OAuth

 It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.

 Without going too far down the rabbit hole, here's a description of the interaction of these technologies:

-* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to.  For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
+* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
 * OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
 * Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
