I'm sorry, but the provided knowledge sources do not contain information about the webfinger JWKS config. However, they do provide information about JSON Web Keys (JWKs) and JSON Web Key Sets (JWKS). JWKs are a JSON data structure that represents a cryptographic key, as specified in IETF RFC7517. They are used to represent public and private keys in a standard format that is widely supported across all languages. JWKS is a JSON object that represents a set of JSON Web Keys. For more specific information about webfinger JWKS config, I would recommend checking the official Ory documentation or other relevant resources.
