The load_der_public_key method and the load_pem_private_key method were
removed from Backend class in cryptography 42.0.0[1].
Closes#713
[1] 41daf2d86d
This test is meant to intentionally trigger an exception in the cryptography library
by creating a CMAC with a non-block cipher algorithm, IDEA.
That doesn't work any more because IDEA is now treated as a block cipher algorithm.
To fix this, we now use the ARC4 algorithm instead,
which does trigger the expected exception.
The cryptography release 39.0.0 added a new parameter to the
backend.load_pem_private_key and backend.load_der_private_key
that's required. This patch uses the serialization method to load keys
because there the new parameter is optional.

This patch fixes the tests test_encrypt_decrypt_asymmetric
This change fixes violations of E722, the use of except without
specifying an exception type. For now the high-level Exception
class is used as a generic catchall. In the future these cases
will be updated to handle the specific exceptions expected.
This change updates how private key bytes are loaded when signing
data. The prior approach required binascii to unhexlify the byte
string. The current approach removes this requirement, matching
the rest of the library. All unit tests have been updated to
reflect this change.
This change adds signature verification support to the server
cryptography engine. Only RSA-based signatures are currently
supported. Unit tests have been added to verify the new
functionality.
This change updates the encrypt/decrypt support in the cryptography
engine to support asymmetric key algorithms, specifically RSA. Unit
tests have been added to validate the new functionality.
This change adds the Decrypt operation to the server. Support is
currently limited to symmetric decryption only. The decryption key
used with the operation must be in the Active state and it must
have the Decrypt bit set in its cryptographic usage mask.
This change fixes key wrapping support in the cryptography engine.
The original implementation used a CryptographicAlgorithm enum to
determine what key wrapping algorithm to use for key wrapping.
Closer inspection of the KMIP spec indicates that a BlockCipherMode
enum should be used instead. The engine has been updated to reflect
this change, as have the corresponding key wrapping unit tests.
This change adds key wrapping support to the CryptographyEngine,
supporting RFC 3394, AES Key Wrap, only. Numerous unit tests from
using test vectors from RFC 3394 are included.
This change adds key derivation functionality to the cryptographic
engine, adding support for multiple key derivation methods,
including encrypting, hashing, HMACing, and specific algorithms
like PBKDF2 and NIST 800-108. Numerous unit tests are included
from established cryptographic testing sources to verify the
added functionality.
This change adds decryption functionality to the cryptographic
engine used by the server. It supports a variety of symmetric
decryption algorithms and block cipher modes. Asymmetric
decryption support will be added in a future patch.
Unit tests and minor updates to surrounding code are included.
