FEDORA-2018-fc576a8e2f

enhancement update in Fedora 27 for python-pycryptodomex

Status: stable 9 months ago

This update provides the latest version of the pycryptodomex python library.

New features

  • Added support for Poly1305 MAC (with AES and ChaCha20 ciphers for key derivation).
  • Added support for ChaCha20-Poly1305 AEAD cipher.
  • New parameter output for Crypto.Util.strxor.strxor, Crypto.Util.strxor.strxor_c, encrypt and decrypt methods in symmetric ciphers (Crypto.Cipher package). output is a pre-allocated buffer (a bytearray or a writeable memoryview) where the result must be stored. This requires less memory for very large payloads; it is also more efficient when encrypting (or decrypting) several small payloads.

Resolved issues

  • GH#266: AES-GCM hangs when processing more than 4GB at a time on x86 with PCLMULQDQ instruction.

Breaks in compatibility

  • Drop support for Python 3.3.
  • Remove Crypto.Util.py3compat.unhexlify and Crypto.Util.py3compat.hexlify.
  • With the old Python 2.6, use only ctypes (and not cffi) to interface to native code.
