python3-crcmod binary package in Ubuntu Noble arm64

 CRCmod generates objects that compute the Cyclic Redundancy Check (CRC). It
 allows the use of any 8, 16, 24, 32, or 64 bit CRC. You can generate a Python
 function for the selected polynomial or an instance of the Crc class which
 provides the same interface as the md5 and sha modules from the Python
 standard library. A "Crc" class instance can also generate C/C++ source code
 that can be used in another application.
 .
 This package contains the Python 3.x module.
