What is CRC32?
CRC32 (Cyclic Redundancy Check 32-bit) is a type of checksum function used to detect accidental changes to raw data. It's widely used in digital networks and storage devices like ZIP files, Ethernet, and PNG images.
Usage Note
While CRC32 is great at detecting errors in transmission, it is not cryptographically secure. It can be easily manipulated to produce a specific checksum, so it should only be used for integrity checks, not for security.
