r s r c @ s e Zd ZdZdS )�MissingBackendErrora� Error raised if multi-backend handler has no available backends;
or if specifically requested backend is not available.
:exc:`!MissingBackendError` derives
from :exc:`RuntimeError`, since it usually indicates
lack of an external library or OS feature.
This is primarily raised by handlers which depend on
external libraries (which is currently just
:class:`~passlib.hash.bcrypt`).

such as if ``crypt.crypt()`` returning a malformed hash.

r # s r c @ s e Zd ZdZdS )�PasswordValueErrora�
Error raised if a password can't be hashed / verified for various reasons.
This exception derives from the builtin :exc:`!ValueError`.
May be thrown directly when password violates internal invariants of hasher
(e.g. some don't support NULL characters). Hashers may also throw more specific subclasses,
such as :exc:`!PasswordSizeError`.
.. versionadded:: 1.7.3

r c @ s e Zd ZdZdZddd�ZdS )�PasswordSizeErrora
Error raised if a password exceeds the maximum size allowed
by Passlib (by default, 4096 characters); or if password exceeds
a hash-specific size limitation.
This exception derives from :exc:`PasswordValueError` (above).
Many password hash algorithms take proportionately larger amounts of time and/or
memory depending on the size of the password provided. This could present
a potential denial of service (DOS) situation if a maliciously large
password is provided to an application. Because of this, Passlib enforces
a maximum size limit, but one which should be *much* larger
than any legitimate password. :exc:`PasswordSizeError` derives
from :exc:`!ValueError`.
.. note::
Applications wishing to use a different limit should set the
``PASSLIB_MAX_PASSWORD_SIZE`` environmental variable before
Passlib is loaded. The value can be any large positive integer.

Error raised if password would be truncated by hash.
This derives from :exc:`PasswordSizeError` (above).
Hashers such as :class:`~passlib.hash.bcrypt` can be configured to raises
this error by setting ``truncate_error=True``.

Base error raised by v:mod:`passlib.totp` when

Usually one of the more specific subclasses below will be raised:
* :class:`MalformedTokenError` -- invalid chars, too few digits
* :class:`InvalidTokenError` -- no match found
* :class:`UsedTokenError` -- match found, but token already used

Error raised by :class:`~passlib.crypto.lookup_hash` if hash name is not recognized.
This exception derives from :exc:`!ValueError`.
As of version 1.7.3, this may also be raised if hash algorithm is known,
but has been disabled due to FIPS mode (message will include phrase "disabled for fips").
As of version 1.7.4, this may be raised if a :class:`~passlib.context.CryptContext`
is unable to identify the algorithm used by a password hash.

r( � s r( c @ s e Zd ZdZdS )�PasslibConfigWarningaH Warning issued when non-fatal issue is found related to the configuration
of a :class:`~passlib.context.CryptContext` instance.
This occurs primarily in one of two cases:
* The CryptContext contains rounds limits which exceed the hard limits
imposed by the underlying algorithm.
* An explicit rounds value was provided which exceeds the limits
imposed by the CryptContext.
In both of these cases, the code will perform correctly & securely;
but the warning is issued as a sign the configuration may need updating.

or hash string passed to a passlib hash class.
This occurs primarily in one of two cases:
* A rounds value or other setting was explicitly provided which
exceeded the handler's limits (and has been clamped
by the :ref:`relaxed<relaxed-keyword>` flag).
* A malformed hash string was encountered which (while parsable)
should be re-encoded.

that the developers would love to hear under what conditions it occurred.

helper used to display sensitive data (hashes etc) within error messages.
currently returns placeholder test UNLESS unittests are running,
in which case the real value is displayed.
mainly useful to prevent hashes / secrets from being exposed in production tracebacks;
while still being visible from test failures.
