Assess your knowledge of hash functions and their properties

All Quizzes Start Lesson

Question 1

What is a hash function?

A function that encrypts data A function that maps data of arbitrary size to fixed-size values A function that compresses files A function that sorts data

Question 2

Which property is essential for a cryptographic hash function?

Reversibility Compression Collision resistance Encryption capability

Question 3

What is the avalanche effect in hash functions?

Hash functions get slower with more data Small changes in input cause large changes in output Hash collisions increase exponentially Multiple inputs produce the same hash

Question 4

What is a hash collision?

When a hash function fails to run When two different inputs produce the same hash output When the hash output is too long When the hash function is reversed

Question 5

Why are hash functions considered one-way functions?

They only work with numbers They can only hash data once It's computationally infeasible to reverse them They always produce the same output
