||� dS )a� Creates a JWT object.
:param header: A dict or a JSON string with the JWT Header data.
:param claims: A dict or a string with the JWT Claims data.
:param jwt: a 'raw' JWT token
:param key: A (:class:`jwcrypto.jwk.JWK`) key to deserialize
the token. 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.
