Exceptions

The CryptoFactoryError Exception class is used to catch errors raised by underneath Crypto providers (based on different libraries). In such implementation, managing exceptions on the client side is simplified.

Example:

>>> cf.decrypt('BAD_DATA', mode='aes')
Traceback (most recent call last):
...
binascii.Error: Incorrect padding

# Then followed by...
Traceback (most recent call last):
...
ValueError: Invalid key or string

# Finally caught by CryptoFactoryError...
Traceback (most recent call last):
...
CryptoFactoryError: Unable to decrypt with Crypto service: aes

Usage:

>>> from crypto_factory.exceptions import CryptoFactoryError
>>> try:
...     cf.decrypt('BAD_DATA', mode='aes')
... except CryptoFactoryError as err:
...     print("CryptoFactory error: {0}".format(err))
...
CryptoFactory error: Unable to decrypt with Crypto service: aes
