The secret key should be a random string of ``bytes`` and should not be saved to code or version control. Different salts should be used to distinguish signing in different contexts. See :doc:`/concepts` for information about the security of the secret key and salt. :param secret_key: The secret key to sign and verify with. Can be a list of keys, oldest to newest, to support key rotation. :param salt: Extra key to combine with ``secret_key`` to distinguish signatures in different contexts. :param sep: Separator between the signature and value. :param key_derivation: How to derive the signing key from the secret key and salt. Possible values are ``concat``, ``django-concat``, or ``hmac``. Defaults to :attr:`default_key_derivation`, which defaults to ``django-concat``. :param digest_method: Hash function to use when generating the HMAC signature. Defaults to :attr:`default_digest_method`, which defaults to :func:`hashlib.sha1`. Note that the security of the hash alone doesn't apply when used intermediately in HMAC. :param algorithm: A :class:`SigningAlgorithm` instance to use instead of building a default :class:`HMACAlgorithm` with the ``digest_method``. .. versionchanged:: 2.0 Added support for key rotation by passing a list to ``secret_key``. .. versionchanged:: 0.18 ``algorithm`` was added as an argument to the class constructor. .. versionchanged:: 0.14 ``key_derivation`` and ``digest_method`` were added as arguments to the class constructor. r5r6 django-concatrGdefault_key_derivationNc@[U5Ul[U5UlUR[;a [ S5eUb [U5nOSnX lUc URnX@lUc URnXPl Uc[UR5nX`l g)NzThe given separator cannot be used because it may be contained in the signature itself.
