How to calculate CRC32 with Python to match online results?

Question

I\'m trying to calculate/generate the CRC32 hash of some random strings using Python but they do not match the values I generate from online sources. Here is what I\'m doing

Answer 1

zlib.crc32 documentation suggests using the following approach "to generate the same numeric value across all Python versions and platforms".

import zlib
hex(zlib.crc32(b'hello-world') & 0xffffffff)

The result is 0xb1d4025b as expected.
