What is One-Way Hash Function? A one-way hash function maps an arbitrary-length input message M to a fixed-length output hash H(M) such that the following properties hold: * One-way: Given a hash H(M), it is difficult to find the message M. * Second preimage resistant: Given a message M1, it is difficult to find another message M2 such that H(M1) = H(M2). * Collision resistant: It is difficult to find two messages M1 and M2 such that H(M1) = H(M2).
