A password can be compared to a stored hash using :func:`check_password_hash`. The following methods are supported: - ``scrypt``, the default. The parameters are ``n``, ``r``, and ``p``, the default is ``scrypt:32768:8:1``. See :func:`hashlib.scrypt`. - ``pbkdf2``, less secure. The parameters are ``hash_method`` and ``iterations``, the default is ``pbkdf2:sha256:600000``. See :func:`hashlib.pbkdf2_hmac`. Default parameters may be updated to reflect current guidelines, and methods may be deprecated and removed if they are no longer considered secure. To migrate old hashes, you may generate a new hash when checking an old hash, or you may contact users with a link to reset their password. :param password: The plaintext password. :param method: The key derivation function and parameters. :param salt_length: The number of characters to generate for the salt. .. versionchanged:: 3.1 The default iterations for pbkdf2 was increased to 1,000,000. .. versionchanged:: 2.3 Scrypt support was added. .. versionchanged:: 2.3 The default iterations for pbkdf2 was increased to 600,000. .. versionchanged:: 2.3 All plain hashes are deprecated and will not be supported in Werkzeug 3.0. $)rr:)r3r2 salt_lengthr!h actual_methods r generate_password_hashr@Is9D K D%fdH=A}_AdV1QC ((rc |jdd\}}}tjt |||d|S#t$rYywxYw)aASecurely check that the given stored password hash, previously generated using :func:`generate_password_hash`, matches the given password.
