Q3 / 100
What is a hash function in cryptography?
Correct! Well done.
Incorrect.
The correct answer is B) A one-way function producing a fixed-size digest from any input, where it is computationally infeasible to reverse or find two inputs with the same output
B
Correct Answer
A one-way function producing a fixed-size digest from any input, where it is computationally infeasible to reverse or find two inputs with the same output
Explanation
Cryptographic hash functions (SHA-256, SHA-3) are one-way (no reversal), deterministic, and collision-resistant. Used for password storage, digital signatures, and data integrity checks.
