jrSS jrSS jrSS jrSrg)�Signer�L a^ A signer securely signs bytes, then unsigns them to verify that27the value hasn't been changed.28 29The secret key should be a random string of ``bytes`` and should not30be saved to code or version control. Different salts should be used31to distinguish signing in different contexts. See :doc:`/concepts`32for information about the security of the secret key and salt.33 34:param secret_key: The secret key to sign and verify with. Can be a35 list of keys, oldest to newest, to support key rotation.36:param salt: Extra key to combine with ``secret_key`` to distinguish37 signatures in different contexts.38:param sep: Separator between the signature and value.39:param key_derivation: How to derive the signing key from the secret40 key and salt. Possible values are ``concat``, ``django-concat``,41 or ``hmac``. Defaults to :attr:`default_key_derivation`, which42 defaults to ``django-concat``.43:param digest_method: Hash function to use when generating the HMAC44 signature. Defaults to :attr:`default_digest_method`, which45 defaults to :func:`hashlib.sha1`. Note that the security of the46 hash alone doesn't apply when used intermediately in HMAC.47:param algorithm: A :class:`SigningAlgorithm` instance to use48 instead of building a default :class:`HMACAlgorithm` with the49 ``digest_method``.50 51.. versionchanged:: 2.052 Added support for key rotation by passing a list to53 ``secret_key``.54 55.. versionchanged:: 0.1856 ``algorithm`` was added as an argument to the class constructor.57 58.. versionchanged:: 0.1459 ``key_derivation`` and ``digest_method`` were added as arguments60 to the class constructor.61r5 r6 �
