 # keyfunc
 
 The purpose of this package is to provide a
-[`jwt.Keyfunc`](https://pkg.go.dev/github.com/golang-jwt/jwt/v4#Keyfunc) for the

 There is legacy support for `github.com/dgrijalva/jwt-go` and its popular forks. It's in a separate project to keep this
 project minimal. If your use case supports a legacy fork, please

 It's common for an identity provider, such as [Keycloak](https://www.keycloak.org/)
 or [Amazon Cognito (AWS)](https://aws.amazon.com/cognito/) to expose a JWKS via an HTTPS endpoint. This package has the
 ability to consume that JWKS and produce a
