exception pskc.exceptions.PSKCError

The base class for all exceptions that the module will raise. In some cases third-party code may raise additional exceptions.

exception pskc.exceptions.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 PSKC class is instantiated).

exception pskc.exceptions.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 secret, counter, time_offset, time_interval or time_drift attributes of the Key class).

exception pskc.exceptions.KeyDerivationError

Raised when key derivation fails due to an unsupported algorithm or missing information in the PSKC file.
