Which term refers to the fixed-size output produced by a hash operation?

• A. Hash Function
• B. Privacy
• C. Non-Repudiation
• D. Hash Digest

Answer: (D)

The fixed-size output produced by a hash operation is called the hash digest, or simply the digest. A hash function takes input of any length and deterministically produces a short, fixed-length value that represents the data. This digest is used to verify integrity because even a tiny change in the input yields a different digest. The other terms relate to different concepts: the hash function is the algorithm itself, while privacy and non-repudiation are security properties, not the output. So the correct term for the fixed-size output is the hash digest.
