WebMar 14, 2024 · Hashing is similar to encryption in that it scrambles the input data into a randomized or near-randomized output data. Hashing differs significantly from encryption, however, in that it is a one-way process. There is no easy way to unscramble the data, interpret the output, or reverse-engineer the input.

A good hash function should map the expected inputs as evenly as possible over its output range. That is, every hash value in the output range should be generated with roughly the same probability. The reason for this last requirement is that the cost of hashing-based methods goes up sharply as the number of collisions—pairs of inputs that are mapped to the same hash value—increases. If some hash values are more likely to occur than others, a larger fraction of t… WebMar 21, 2024 · Hashing is a technique or process of mapping keys, and values into the hash table by using a hash function.
