Introduction to Hashing: Hashing is a method of turning some kind of data into a relatively small number that may serve as a digital "fingerprint" of the data. Protect sensitive information with our user-friendly, client-side processing. (3) Convert hexagons to GeoJSON features (Polygon / Point), show it on map. In an ideal world, with "perfect" hash functions, the outputs would be distributed uniformly, just as if the hash functions were random. The first hash function is used to compute the initial hash value, and the second hash function is used to compute the step size for the probing sequence. Changes the background of password entry fields to a four-color visual hash. It works by using two hash functions to compute two different hash values for a given key. 4.
