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. WebA cryptographic hash function is a hash function which takes an input (or 'message') and returns a fixed-size string of bytes. The string is called the 'hash value', 'message digest', …
