The recommendation is to upgrade to at least 1.15 See issue +[dgrijalva/jwt-go#216](https://github.com/dgrijalva/jwt-go/issues/216) for more +detail. + +**SECURITY NOTICE:** It's important that you [validate the `alg` presented is +what you +expect](https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/). +This library attempts to make it easy to do the right thing by requiring key +types to match the expected alg, but you should take the extra step to verify it in +your usage. See the examples provided. + +### Supported Go versions + +Our support of Go versions is aligned with Go's [version release +policy](https://golang.org/doc/devel/release#policy). So we will support a major +version of Go until there are two newer major releases. We no longer support +building jwt-go with unsupported Go versions, as these contain security +vulnerabilities that will not be fixed. + +## 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](https://datatracker.ietf.org/doc/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 [RFC +7519](https://datatracker.ietf.org/doc/html/rfc7519) 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 HMAC SHA, RSA, +RSA-PSS, and ECDSA, though hooks are present for adding your own. + +## Installation Guidelines + +1. To install the jwt package, you first need to have + [Go](https://go.dev/doc/install) installed, then you can use the command + below to add `jwt-go` as a dependency in your Go program. + +```sh +go get -u github.com/golang-jwt/jwt/v5 +``` + +2. Import it in your code: + +```go +import "github.com/golang-jwt/jwt/v5" +``` + +## Usage + +A detailed usage guide, including how to sign and verify tokens can be found on +our [documentation website](https://golang-jwt.github.io/jwt/usage/create/). + +## Examples + +See [the project documentation](https://pkg.go.dev/github.com/golang-jwt/jwt/v5) +for examples of usage: + +* [Simple example of parsing and validating a + token](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#example-Parse-Hmac) +* [Simple example of building and signing a + token](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#example-New-Hmac) +* [Directory of + Examples](https://pkg.go.dev/github.com/golang-jwt/jwt/v5#pkg-examples) + +## Compliance + +This library was last reviewed to comply with [RFC +7519](https://datatracker.ietf.org/doc/html/rfc7519) dated May 2015 with a few +notable differences: + +* In order to protect against accidental use of [Unsecured + JWTs](https://datatracker.ietf.org/doc/html/rfc7519#section-6), 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 +backward-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 `main`. Periodically, versions will be tagged from +`main`. You can find all the releases on [the project releases +page](https://github.com/golang-jwt/jwt/releases). + +**BREAKING CHANGES:** A full list of breaking changes is available in +`VERSION_HISTORY.md`. See [`MIGRATION_GUIDE.md`](./MIGRATION_GUIDE.md) for more information on updating +your code. + +## Extensions + +This library publishes all the necessary components for adding your own signing +methods or key functions.

To retrieve the current changes of each version, please refer to the change-log of the specific release versions on https://github.com/golang-jwt/jwt/releases. + +## 4.0.0 + +* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`. + +## 3.2.2 + +* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)). +* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)). +* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)). +* Optimized allocations ([#33](https://github.com/golang-jwt/jwt/pull/33)). + +## 3.2.1 + +* **Import Path Change**: See MIGRATION_GUIDE.md for tips on updating your code + * Changed the import path from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt` +* Fixed type confusing issue between `string` and `[]string` in `VerifyAudience` ([#12](https://github.com/golang-jwt/jwt/pull/12)). This fixes CVE-2020-26160 + +#### 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 + * Dropped support for `[]byte` keys when using RSA signing methods. This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods. + * `ParseFromRequest` has been moved to `request` subpackage and usage has changed + * The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`. The default value is type `MapClaims`, which is an alias to `map[string]interface{}`. This makes it possible to use a custom type when decoding claims. +* Other Additions and Changes + * Added `Claims` interface type to allow users to decode the claims into a custom type + * Added `ParseWithClaims`, which takes a third argument of type `Claims`. Use this function instead of `Parse` if you have a custom type you'd like to decode into. + * Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage + * Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims` + * Added new interface type `Extractor`, which is used for extracting JWT strings from http requests. Used with `ParseFromRequest` and `ParseFromRequestWithClaims`. + * Added several new, more specific, validation errors to error type bitmask + * Moved examples from README to executable example files + * Signing method registry is now thread safe + * Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser) + +#### 2.7.0 + +This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes. + +* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying +* Error text for expired tokens includes how long it's been expired +* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM` +* Documentation updates + +#### 2.6.0 + +* Exposed inner error within ValidationError +* Fixed validation errors when using UseJSONNumber flag +* Added several unit tests + +#### 2.5.0 + +* Added support for signing method none. You shouldn't use this. The API tries to make this clear. +* Updated/fixed some documentation +* Added more helpful error message when trying to parse tokens that begin with `BEARER ` + +#### 2.4.0 + +* Added new type, Parser, to allow for configuration of various parsing parameters + * You can now specify a list of valid signing methods. Anything outside this set will be rejected. + * You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON +* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go) +* Fixed some bugs with ECDSA parsing + +#### 2.3.0 + +* Added support for ECDSA signing methods +* Added support for RSA PSS signing methods (requires go v1.4) + +#### 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`.
