A password can be compared to a stored hash27using :func:`check_password_hash`.28 29The following methods are supported:30 31- ``scrypt``, the default. The parameters are ``n``, ``r``, and ``p``, the default32 is ``scrypt:32768:8:1``. See :func:`hashlib.scrypt`.33- ``pbkdf2``, less secure. The parameters are ``hash_method`` and ``iterations``,34 the default is ``pbkdf2:sha256:600000``. See :func:`hashlib.pbkdf2_hmac`.35 36Default parameters may be updated to reflect current guidelines, and methods may be37deprecated and removed if they are no longer considered secure. To migrate old38hashes, you may generate a new hash when checking an old hash, or you may contact39users with a link to reset their password.40 41:param password: The plaintext password.42:param method: The key derivation function and parameters.43:param salt_length: The number of characters to generate for the salt.44 45.. versionchanged:: 3.146 The default iterations for pbkdf2 was increased to 1,000,000.47 48.. versionchanged:: 2.349 Scrypt support was added.50 51.. versionchanged:: 2.352 The default iterations for pbkdf2 was increased to 600,000.53 54.. versionchanged:: 2.355 All plain hashes are deprecated and will not be supported in Werkzeug 3.0.56�$)r& rG )r@ r? � salt_lengthr. �h�
