Fedora Update Notification

Name : python-pycryptodomex
Product : Fedora 35
Version : 3.10.4
Release : 1.fc35
URL :
http://www.pycryptodome.org/
Summary : A self-contained cryptographic library for Python
Description :
PyCryptodome is a self-contained Python package of low-level cryptographic
primitives. It's a fork of PyCrypto. It brings several enhancements with respect
to the last official version of PyCrypto (2.6.1), for instance:
* Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
* Accelerated AES on Intel platforms via AES-NI
* Elliptic curves cryptography (NIST P-256 curve only)
* Better and more compact API (nonce and iv attributes for ciphers, automatic
generation of random nonces and IVs, simplified CTR cipher mode, and more)
* SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
* Salsa20 and ChaCha20 stream ciphers
* scrypt and HKDF
* Deterministic (EC)DSA
* Password-protected PKCS#8 key containers
* Shamir's Secret Sharing scheme
* Random numbers get sourced directly from the OS (and not from a CSPRNG in
userspace)
* Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
* Major clean ups and simplification of the code base
PyCryptodome is not a wrapper to a separate C library like OpenSSL. To the
largest possible extent, algorithms are implemented in pure Python. Only the
pieces that are extremely critical to performance (e.g. block ciphers) are
implemented as C extensions.
Note: all modules are installed under the Cryptodome package to avoid conflicts
with the PyCrypto library.

Update Information:
## 3.10.4 (25 September 2021) ### Resolved issues * Output of
``Crypto.Util.number.long_to_bytes()`` was not always a multiple of
``blocksize``. ## 3.10.3 (22 September 2021) ### Resolved issues * GH#376:
Fixed symbol conflict between different versions of ``libgmp``. * GH#481:
Improved robustness of PKCS#1v1.5 decryption against timing attacks. * GH#506
and GH#509: Fixed segmentation faults on Apple M1 and other Aarch64 SoCs, when
the GMP library add accessed via ``ctypes``. Do not use GMP's own sscanf and
snprintf routines: instead, use simpler conversion routines. * GH#510:
Workaround for ``cffi`` calling ``ctypes.util.find_library()``, which invokes
``gcc`` and ``ld`` on Linux, considerably slowing down all imports. On certain
configurations, that may also leave temporary files behind. * GH#517: Fix RSAES-
OAEP, as it didn't always fail when zero padding was incorrect. ### New
features * Added support for SHA-3 hash functions to HMAC.
