What is CRC32?
CRC32 (32-bit Cyclic Redundancy Check) is a checksum algorithm used to detect errors in transmitted or stored data. It produces a 32-bit value (8 hex digits) derived from the input data.
Widely used in network protocols (Ethernet, ZIP, PNG, gzip) for integrity verification. Not suitable for cryptographic use — only for detecting accidental data corruption.
