A hash function converts an input value of any arbitrary size to a fixed-size value. Thus, the input can be of any length but the output generated is always of a fixed length. The output generated is called hash values or hashes.

WebA one-way permutation is a one-way function that is also a permutation—that is, a one-way function that is bijective. One-way permutations are an important cryptographic primitive, and it is not known if their existence is implied by the existence of one-way functions. A trapdoor one-way function or trapdoor permutation is a special kind of ...

Cryptographic hash functions are cryptographic algorithms that generate and use keys to encrypt data, and such functions may be viewed as keys themselves. They take a message of any length as input, and output a short, fixed-length hash , which can be used in (for example) a digital signature.
