Also known as: CRC-32, cyclic redundancy check
A 32-bit checksum used throughout Usenet binaries to detect corruption. Every yEnc =yend line carries the CRC32 of the data it closes, SFV files list one per archive volume, and RAR stores one per compressed file. A mismatch proves the bytes changed in transit or on disk. Detection only: identifying damage is what triggers PAR2 repair, which does the actual reconstruction.
