Hash Function maps arbitrary sized-data to a fixed-size value.

A hash function takes input data of any length and produces a fixed-size output. The operation itself is what performs the mapping, so it’s described by the term hash function. The fixed-size result is the hash value or digest, but the statement is defining the process, not the output. Attestation and identity proofing are security concepts that deal with verifying state or identity, not the data-to-fixed-size mapping.
