|

**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.

|

**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage. See the examples provided.

## Usage Tips

|

@ -68,6 +75,14 @@ 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.

## `jwt-go` Version History
|
||||
|
||||
#### 3.2.0
|
||||
|
||||
* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
|
||||
* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
|
||||
* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
|
||||
* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
|
||||
|
||||
#### 3.1.0
|
||||
|
||||
* Improvements to `jwt` command line tool
|
||||
* Added `SkipClaimsValidation` option to `Parser`
|
||||
* Documentation updates
|
||||
|
||||
#### 3.0.0
|
||||
|
||||
* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
