-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2025-b61234cbf7 2025-07-21 01:17:49.257208+00:00 -------------------------------------------------------------------------------- Name : python-pycryptodomex Product : Fedora 41 Version : 3.23.0 Release : 1.fc41 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: 3.23.0 (17 May 2025) ++++++++++++++++++++++++++ New features Added cipher modes Key Wrap (KW, RFC3394) and Key Wrap with Padding (KWP, RFC5649). Both are defined also in NIST SP 800-38F. Wheels for Windows ARM. Resolved issues GH#862: For HashEdDSA and Ed448, sign() and verify() modified the state of the XOF. 3.22.0 (16 March 2025) ++++++++++++++++++++++++++ New features Added support for HPKE (RFC 9180). Resolved issues GH#812: CCM ciphers will now fail before encrypting (or decrypting) data beyond the limit imposed by the nonce length. GH#846: fix infinite loop with RC4 for data larger than 4GB. GH#852: handle correctly invalid PEM files with less than 3 lines. Other changes Remove support for Python 3.6. -------------------------------------------------------------------------------- ChangeLog: * Sat Jul 12 2025 Mohame El Morabity <melmorabity@xxxxxxxxxxxxxxxxx> - 3.23.0-1 - Update to 3.23.0 -------------------------------------------------------------------------------- References: [ 1 ] Bug #2352746 - python-pycryptodomex-3.23.0 is available https://bugzilla.redhat.com/show_bug.cgi?id=2352746 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
