For what purpose can a file hash be used?

Answer and explanation

Correct answer: To verify file integrity and detect changes

The governing concept is integrity verification using a digest. A hash function produces a value derived from a file’s contents; even a small change will normally produce a different value. Comparing a downloaded file’s hash with an official value can therefore reveal corruption or alteration. A hash does not print, transfer ownership, or lock the computer, and it is not a replacement for encryption. Option B is correct.
