Question

Most attacks on hash functions involve:

A. Finding collisions.
B. Pre-generating millions of hashes and comparing them to the plain text that generated it.
C. Really good random guessing.



A, B, and C


A and B


A and C


B and C

Answer 1

The correct answer is **A and B**.

Most attacks on hash functions focus on:

- **Finding collisions (A)**: This is when two different inputs produce the same hash output, which can be exploited in various ways.
- **Pre-generating millions of hashes and comparing them to the plaintext that generated it (B)**: This refers to the use of techniques like rainbow tables to find a matching hash.

While good random guessing (C) is a method that can be used in some contexts, it is not a primary focus in attacks on hash functions compared to collision finding and pre-computation. Thus, the combination of A and B is the most accurate choice.
