E.g. ZFS uses non-cryptographical hashes to detect bitrot. TCP and IPv4 use a non-cryptographical hash to detect packet corruption. Etc.

- codinghorror 15y agoterminology issue, I guess, I'd call those checksums -- where speed is the overriding concern and you're not worried about attackers changing the data underneath you. (And you actually need to uniquely identify the data in a reliable way..)
- scott_s 15y agoSure, it's a terminology issue, but as several others have pointed out, you're the only one using your terminology. So expect people to be confused when you try to explain these things using your definitions.
- parenthephobia 15y agoIn the case of TCP/IP, everyone calls the checksum a checksum, and nobody calls it a hash.
