 - `getPrivateKeyId()`: Its called during token signing and it should return the id of the key that identifies the one returned by `getPrivateKey()`. This value is preferred over the one set in the `JWTCreator.Builder#withKeyId(String)` method. If you don't need to set a `kid` value avoid instantiating an Algorithm using a `KeyProvider`.
 
 
-The following example shows how this would work with `JwkStore`, an imaginary [JWK Set](https://auth0.com/docs/jwks) implementation. For simple key rotation using JWKS, try the [jwks-rsa-java](https://github.com/auth0/jwks-rsa-java) library.
