WebMar 23, 2024 · In mathematics, this is known as the Pigeonhole Principle, and in cryptography, hash collisions are one example of its manifestation. Hash Collisions. Why … WebThe only difference that I can see is that in a second preimage attack, m1 already exists and is known to the attacker. However, that doesn't strike me as being significant - the end goal is still to find two messages that produce the same hash.
