-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2021-02b6241872 2021-09-30 00:51:55.645472 --------------------------------------------------------------------------------
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. -------------------------------------------------------------------------------- ChangeLog:
