WebJul 9, 2024 · First lets assume the output of a hash function is uniformly randomly distributed. The probability of 2 hash values being the same (being a collision) is ( 1 / 2 256) = 2 − 256. We have 2 256 outputs, so there are 2 256 ∗ ( 2 256 − 1) 2 pairs of output hashes. Each of these pairs has probability 2 − 256 of being the same.
