A (:class:`jwcrypto.jwk.JWKSet`) can also be used. :param algs: An optional list of allowed algorithms :param default_claims: An optional dict with default values for registered claims. A None value for NumericDate type claims will cause generation according to system time. Only the values from RFC 7519 - 4.1 are evaluated. :param check_claims: An optional dict of claims that must be present in the token, if the value is not None the claim must match exactly. :param expected_type: An optional string that defines what kind of token to expect when validating a deserialized token. Supported values: "JWS" or "JWE" If left to None the code will try to detect what the expected type is based on other parameters like 'algs' and will default to JWS if no hints are found. It has no effect on token creation. Note: either the header,claims or jwt,key parameters should be provided as a deserialization operation (which occurs if the jwt is provided) will wipe any header or claim provided by setting those obtained from the deserialization of the jwt token. Note: if check_claims is not provided the 'exp' and 'nbf' claims are checked if they are set on the token but not enforced if not set. Any other RFC 7519 registered claims are checked only for format conformance.
