See the +[`MIGRATION_GUIDE.md`](./MIGRATION_GUIDE.md) for more information. Version +v5.0.0 introduces major improvements to the validation of tokens, but is not +entirely backwards compatible. + +> After the original author of the library suggested migrating the maintenance +> of `jwt-go`, a dedicated team of open source maintainers decided to clone the +> existing library into this repository. See +> [dgrijalva/jwt-go#462](https://github.com/dgrijalva/jwt-go/issues/462) for a +> detailed discussion on this topic. + + +**SECURITY NOTICE:** Some older versions of Go have a security issue in the +crypto/elliptic. 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 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 which 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 +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 `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` for more information on updating +your code. + +## Extensions + +This library publishes all the necessary components for adding your own signing +methods or key functions. Simply implement the `SigningMethod` interface and +register a factory method using `RegisterSigningMethod` or provide a +`jwt.Keyfunc`. + +A common use case would be integrating with different 3rd party signature +providers, like key management services from various cloud providers or Hardware +Security Modules (HSMs) or to implement additional standards. + +| Extension | Purpose | Repo | +| --------- | -------------------------------------------------------------------------------------------------------- | ------------------------------------------ | +| GCP | Integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS) | https://github.com/someone1/gcp-jwt-go | +| AWS | Integrates with AWS Key Management Service, KMS | https://github.com/matelang/jwt-go-aws-kms | +| JWKS | Provides support for JWKS ([RFC 7517](https://datatracker.ietf.org/doc/html/rfc7517)) as a `jwt.Keyfunc` | https://github.com/MicahParks/keyfunc | + +*Disclaimer*: Unless otherwise specified, these integrations are maintained by +third parties and should not be considered as a primary offer by any of the +mentioned cloud providers + +## More + +Go package documentation can be found [on +pkg.go.dev](https://pkg.go.dev/github.com/golang-jwt/jwt/v5). Additional +documentation can be found on [our project +page](https://golang-jwt.github.io/jwt/). + +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.
