# Hash by field name (generic) (`hash`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Column whose name says that it holds a hash value (hash, checksum, digest, fingerprint, hash_value or hash_code) when the algorithm cannot be told from the values. Records of specific algorithms, such as md5hash, sha1hash and sha256hash, refine it.
