A cryptographic hash function should resist attacks on its preimage. ..
■. preimage resistance: for essentially all pre-specified outputs, it is computationally infeasible to find any input that hashes to that output, i.e., given y, it is difficult to find an x such that h(x) = y.
hope it helps!!!!
