Hash Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,

In the computational theory, there is no hash function, only one-way function is said. The so-called one-way function, is a complex definition, you can see the computational theory or cryptography data. The "Human" language describes the one-way
