-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2019-66d7540be9 2019-03-05 05:21:10.106346 --------------------------------------------------------------------------------
Name : python-pycryptodomex Product : Fedora EPEL 7 Version : 3.7.3 Release : 1.el7 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:
# 3.7.3 (19 January 2019) Resolved issues --------------- * GH#258: False positive on PSS signatures when externally provided salt is too long. * Include type stub files for ``Crypto.IO`` and ``Crypto.Util``. # 3.7.2 (26 November 2018) Resolved issues --------------- * GH#242: Fixed compilation problem on ARM platforms. # 3.7.1 (25 November 2018) New features ------------ * Added type stubs to enable static type checking with mypy. Thanks to Michael Nix. * New ``update_after_digest`` flag for CMAC. Resolved issues --------------- * GH#232: Fixed problem with gcc 4.x when compiling ``ghash_clmul.c``. * GH#238: Incorrect digest value produced by CMAC after cloning the object. * Method ``update()`` of an EAX cipher object was returning the underlying CMAC object, instead of the EAX object itself. * Method ``update()`` of a CMAC object was not throwing an exception after the digest was computed (with ``digest()`` or ``verify()``). -------------------------------------------------------------------------------- References:
