This is primarily raised by handlers which depend on external libraries (which is currently just :class:`~passlib.hash.bcrypt`). N�r r r r r r r r r s r c @ s e Zd ZdZdS )�InternalBackendErrorz� Error raised if something unrecoverable goes wrong with backend call; such as if ``crypt.crypt()`` returning a malformed hash. .. versionadded:: 1.7.3 Nr r r r r 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 Nr r r r r r , s 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. .. attribute:: max_size indicates the maximum allowed size. .. versionadded:: 1.6 Nc C s" || _ |d u rd}t�| |� d S )Nz%password exceeds maximum allowed size)�max_sizer r )r r �msgr r r r X s zPasswordSizeError.__init__)N)r r r r r r r r r r r : s r c @ s e Zd ZdZddd�ZdS )�PasswordTruncateErrora] 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``. .. attribute:: max_size indicates the maximum allowed size. .. versionadded:: 1.7 Nc C s, |d u rd|j |jf }t�| |j|� d S )Nz1Password too long (%s truncates to %d characters))r Z truncate_sizer r )r �clsr r r r r p s �z PasswordTruncateError.__init__)Nr r r r r r a s r c @ s e Zd ZdZdS )�PasslibSecurityErrorz� Error raised if critical security issue is detected (e.g. an attempt is made to use a vulnerable version of a bcrypt backend). .. versionadded:: 1.6.3 Nr r r r r r w s r c @ s e Zd ZdZdZddd�ZdS )� TokenErrora� Base error raised by v:mod:`passlib.totp` when a token can't be parsed / isn't valid / etc. Derives from :exc:`!ValueError`.

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. .. versionadded:: 1.7 .. versionchanged: 1.7.3 added 'message' argument. .. versionchanged:: 1.7.4 altered call signature.

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. .. versionadded:: 1.6 Nr r r r r r) � s r) c @ s e Zd ZdZdS )�PasslibHashWarninga� Warning issued when non-fatal issue is found with parameters 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. .. versionadded:: 1.6 Nr r r r r r* � s r* c @ s e Zd ZdZdS )�PasslibRuntimeWarninga8 Warning issued when something unexpected happens during runtime.
