It18can unsign to verify that the data hasn't been changed.19 20The serializer provides :meth:`dumps` and :meth:`loads`, similar to21:mod:`json`, and by default uses :mod:`json` internally to serialize22the data to bytes.23 24The secret key should be a random string of ``bytes`` and should not25be saved to code or version control. Different salts should be used26to distinguish signing in different contexts. See :doc:`/concepts`27for information about the security of the secret key and salt.28 29:param secret_key: The secret key to sign and verify with. Can be a30 list of keys, oldest to newest, to support key rotation.31:param salt: Extra key to combine with ``secret_key`` to distinguish32 signatures in different contexts.33:param serializer: An object that provides ``dumps`` and ``loads``34 methods for serializing data to a string. Defaults to35 :attr:`default_serializer`, which defaults to :mod:`json`.36:param serializer_kwargs: Keyword arguments to pass when calling37 ``serializer.dumps``.38:param signer: A ``Signer`` class to instantiate when signing data.39 Defaults to :attr:`default_signer`, which defaults to40 :class:`~itsdangerous.signer.Signer`.41:param signer_kwargs: Keyword arguments to pass when instantiating42 the ``Signer`` class.43:param fallback_signers: List of signer parameters to try when44 unsigning with the default signer fails. Each item can be a dict45 of ``signer_kwargs``, a ``Signer`` class, or a tuple of46 ``(signer, signer_kwargs)``. Defaults to47 :attr:`default_fallback_signers`.48 49.. versionchanged:: 2.050 Added support for key rotation by passing a list to51 ``secret_key``.52 53.. versionchanged:: 2.054 Removed the default SHA-512 fallback signer from55 ``default_fallback_signers``.56 57.. versionchanged:: 1.158 Added support for ``fallback_signers`` and configured a default59 SHA-512 fallback. This fallback is for users who used the yanked60 1.0.0 release which defaulted to SHA-512.61 62.. versionchanged:: 0.1463 The ``signer`` and ``signer_kwargs`` parameters were added to64 the constructor.65�_PDataSerializer[t.Any]�default_serializerz type[Signer]�default_signerzMlist[dict[str, t.Any] | tuple[type[Signer], dict[str, t.Any]] | type[Signer]]�default_fallback_signersNc � � g r r �r �66secret_key�saltr( �serializer_kwargs�signer�
