The data output of the hash algorithm is called hash value … optic lhayWebThe most important property of hash functions is the size of the hash. A larger hash makes it more difficult to invert the function, and it ensures that the function is collision free. Because hash functions have a fixed output but unlimited inputs, multiple values can produce the same hash. optic leveler
