useKeysFrom

Delegates key look-up to the given registry before consulting this parser's own keys.

Keys registered directly on this builder (via verifyWith or decryptWith) take precedence; the registry is only consulted when no local key matches. This makes it easy to share a central key store across multiple parsers while still allowing each parser to override individual keys locally.

val sharedRegistry = JwtProcessorRegistry()
// keys are added to sharedRegistry elsewhere

val parser = Jwt.parser()
    .useKeysFrom(sharedRegistry)
    .requireIssuer("my-app")
    .build()
