-Version 3 adds several new, frequently requested features. To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code. - -### `Token.Claims` is now an interface type - -The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`. - -`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property. - -The old example for parsing a token looked like this.. - -```go - if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { - fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) - } -``` - -is now directly mapped to... - -```go - if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { - claims := token.Claims.(jwt.MapClaims) - fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) - } -``` - -`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type. - -```go - type MyCustomClaims struct { - User string - *StandardClaims - } - - if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil { - claims := token.Claims.(*MyCustomClaims) - fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt) - } -``` - -### `ParseFromRequest` has been moved - -To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`. - -`Extractors` do the work of picking the token string out of a request. The interface is simple and composable. - -This simple parsing example: - -```go - if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil { - fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) - } -``` - -is directly mapped to: - -```go - if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil { - claims := token.Claims.(jwt.MapClaims) - fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) - } -``` - -There are several concrete `Extractor` types provided for your convenience: - -* `HeaderExtractor` will search a list of headers until one contains content. -* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content. -* `MultiExtractor` will try a list of `Extractors` in order until one returns content. -* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token. -* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument -* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header - - -### RSA signing methods no longer accept `[]byte` keys - -Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse. - -To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types. - -```go - func keyLookupFunc(*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"]) - } - - // Look up key - key, err := lookupPublicKey(token.Header["kid"]) - if err != nil { - return nil, err - } - - // Unpack key from PEM encoded PKCS8 - return jwt.ParseRSAPublicKeyFromPEM(key) - } -``` diff --git a/vendor/github.com/dgrijalva/jwt-go/.gitignore b/vendor/github.com/golang-jwt/jwt/.gitignore similarity index 68% rename from vendor/github.com/dgrijalva/jwt-go/.gitignore rename to vendor/github.com/golang-jwt/jwt/.gitignore index 80bed650e..09573e016 100644 --- a/vendor/github.com/dgrijalva/jwt-go/.gitignore +++ b/vendor/github.com/golang-jwt/jwt/.gitignore @@ -1,4 +1,4 @@ .DS_Store bin - +.idea/ diff --git a/vendor/github.com/dgrijalva/jwt-go/.travis.yml b/vendor/github.com/golang-jwt/jwt/.travis.yml similarity index 65% rename from vendor/github.com/dgrijalva/jwt-go/.travis.yml rename to vendor/github.com/golang-jwt/jwt/.travis.yml index 1027f56cd..036a862f8 100644 --- a/vendor/github.com/dgrijalva/jwt-go/.travis.yml +++ b/vendor/github.com/golang-jwt/jwt/.travis.yml @@ -5,9 +5,7 @@ script: - go test -v ./... go: - - 1.3 - - 1.4 - - 1.5 - - 1.6 - 1.7 - - tip + - 1.8 + - 1.9 + - 1.10 diff --git a/vendor/github.com/dgrijalva/jwt-go/LICENSE b/vendor/github.com/golang-jwt/jwt/LICENSE similarity index 96% rename from vendor/github.com/dgrijalva/jwt-go/LICENSE rename to vendor/github.com/golang-jwt/jwt/LICENSE index df83a9c2f..35dbc2520 100644 --- a/vendor/github.com/dgrijalva/jwt-go/LICENSE +++ b/vendor/github.com/golang-jwt/jwt/LICENSE @@ -1,4 +1,5 @@ Copyright (c) 2012 Dave Grijalva +Copyright (c) 2021 golang-jwt maintainers Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: diff --git a/vendor/github.com/golang-jwt/jwt/MIGRATION_GUIDE.md b/vendor/github.com/golang-jwt/jwt/MIGRATION_GUIDE.md new file mode 100644 index 000000000..c4efbd2a8 --- /dev/null +++ b/vendor/github.com/golang-jwt/jwt/MIGRATION_GUIDE.md @@ -0,0 +1,22 @@ +## Migration Guide (v3.2.1) + +Starting from [v3.2.1](https://github.com/golang-jwt/jwt/releases/tag/v3.2.1]), the import path has changed from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/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. +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.

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.
