Exceptions
==========
.. module:: pskc.exceptions
.. exception:: PSKCError
The base class for all exceptions that the module will raise. In some
cases third-party code may raise additional exceptions.
.. exception:: ParseError
Raised when the PSKC file cannot be correctly read due to invalid XML or
some required element or attribute is missing. This exception should only
be raised when parsing the file (i.e. when the :class:`~pskc.PSKC` class is
instantiated).
.. .. exception:: EncryptionError
Raised when encrypting a value is not possible due to key length issues,
missing or wrong length plain text, or other issues.
.. exception:: DecryptionError
Raised when decrypting a value fails due to missing or incorrect key,
unsupported decryption or MAC algorithm, failed message authentication
check or other error.
This exception is generally raised when accessing encrypted information
(i.e. the :attr:`~pskc.key.Key.secret`, :attr:`~pskc.key.Key.counter`,
:attr:`~pskc.key.Key.time_offset`, :attr:`~pskc.key.Key.time_interval` or
:attr:`~pskc.key.Key.time_drift` attributes of the :class:`~pskc.key.Key`
class).
.. exception:: KeyDerivationError
Raised when key derivation fails due to an unsupported algorithm or
missing information in the PSKC file.
