What is hash function cryptanalysis?

Hash function cryptanalysis is the study of vulnerabilities in hash functions, aiming to find weaknesses that can be exploited.

Why are hash functions important in cybersecurity?

Hash functions are crucial for data integrity, password storage, and digital signatures, ensuring that data remains unchanged.

Can you give an example of a hash function vulnerability?

One notable example is the collision vulnerability found in MD5, where two different inputs produce the same hash output.

How can we protect against hash function vulnerabilities?

Using stronger hash functions like SHA-256, implementing salting, and regularly updating cryptographic practices can enhance security.
