Hash inversion

WebBy definition, a hash function has a finite output range, and infinite range input. Therefore, the pigeonhole principle always applies, whether or not ROM is used. The problem is that the input to a hash function will generally have some pattern to it. Text will cluster differently than images which will cluster differently from video, and so on. WebA full hash inversion has a known computationally infeasible brute-force running time, being O(2^k) where k is the hash size eg SHA256, k=256, and if a pre-image was found …
