pycryptodomex 3.24.0

v3.24.0 - Evreux

on Python PyPI

New features

• Speed up KangarooTwelve by 50% for long messages (1MB or more).
• New parameter threads for Crypto.Hash.KangarooTwelve.new(),
  to hash long messages on several CPU cores (threads=0 for all of them).
  The output does not depend on the number of threads.

Resolved issues

• GH#875: Fixed the Object Identifiers (OID) for BLAKE2.
• Fixed a potential DOS attack when decrypting a password-encrypted PKCS#8 key,
  when the iteration count is enourmous. Decryption will now fail if it exceeds
  50M iterations; the limit can be changed or removed via
  the new max_iteration_count option. Thanks to afldl for reporting.
• Fixed the maximum number of bytes that GCM should encrypt. Thanks to Loganaden Velvindron.
• Fixed ECC operations on 32-bit Windows (x86) wheels: due to a compiler bug in
  Visual Studio 2022, the modular inversion skipped half of the exponent bits,
  producing wrong results.
• Fixed a bug in KangarooTwelve in the scenario where customization string is very
  long (8190 bytes or longer) and the message to hash is empty.

Other changes

• Build Windows wheel with Visual Studio 2022, from Visual Studio 2019.
• Remove support for Python 3.7.
