Question

A primary requirement for a good cryptographic hash function is that the function should not produce too many collisions. A collision in a hash function is when:

Answer 1

two different inputs produce the same output hash value. This can introduce security vulnerabilities and reduce the effectiveness of the hash function in protecting data integrity. A good cryptographic hash function should have a very low probability of collisions occurring, making it extremely difficult for an attacker to find two inputs that produce the same hash value.
