Which of the following is NOT a feature of a cryptographic hash function?

The correct answer is B. Reversible. Cryptographic hash functions are designed to be one-way (irreversible) - you cannot reconstruct the original input from the hash output. The key properties they DO have include: Useful (they serve practical purposes like password storage and data integrity), Unique (a good hash…

Explanation

Cryptographic hash functions are designed to be one-way (irreversible) - you cannot reconstruct the original input from the hash output. The key properties they DO have include: Useful (they serve practical purposes like password storage and data integrity), Unique (a good hash function produces a unique output for each unique input, minimizing collisions), and Deterministic (the same input always produces the same hash output). Reversibility is intentionally absent by design; if hashes could be reversed, they would be useless for securing passwords and verifying data integrity.
