Ideally, the only way to find a message that produces a given hash is to attempt a brute-force search of possible inputs to see if they produce a match, or use a rainbow table of matched hashes. It is a one-way function, that is, a function for which it is practically infeasible to invert or reverse the computation. A cryptographic hash function ( CHF) is a mathematical algorithm that maps data of an arbitrary size (often called the "message") to a bit array of a fixed size (the " hash value", "hash", or "message digest"). ![]()
