WebHash Functions Hash functions. A hash function maps keys to small integers (buckets). An ideal hash function maps the keys to the integers in a random-like manner, so that bucket values are evenly distributed even if there are regularities in the input data. This process can be divided into two steps: Map the key to an integer.
