Which of these is not true in case of secure cryptographic hash function?
A) It is collision-resistant.
B) It is preimage-resistant.
C) It is reversible.
D) It is deterministic.
Answer:
C) It is reversible.
Explanation:
In the case of a secure cryptographic hash function, it should be collision-resistant (two different inputs should not produce the same hash), preimage-resistant (it should be computationally infeasible to determine the original input from its hash), and deterministic (the same input should always produce the same hash). However, it is not reversible, meaning you cannot retrieve the original input from its hash value.
