About CRC32
CRC32 (Cyclic Redundancy Check 32-bit) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.
Purpose: CRC32 is designed to detect errors, not to provide security. It should not be used for cryptographic purposes or to verify data authenticity against malicious changes.
Use cases: File integrity checking, network error detection, ZIP file validation, and Ethernet frame checking.
Output: CRC32 produces a 32-bit (8-character hexadecimal) checksum value.
