If crc or CRC32 is specially designed to catch errors, then what's the point of SHA or md4-5 or any other hashing function? What I did was, I had a 190 mb png file (rendered in 16k resolution with blender lol) and I took its sha256 and CRC32 hash, then I did the same, only changing 1 bit of the image. Just 1 bit. And I got a different crc, but ... 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 on my PC, >>> import binascii >>> binascii.crc32('hello-world') -1311505829 Another approach, >>> import zlib >>> zlib.crc32('hello-world') -1311505829 The fact that the above results are identical tells me that I'm calling ...

CRC32 is a checksum algorithm that detects if a message was not modified. It is widely used: for example, sending packages through the Ethernet network implies a calculation of the checksum.
