A hash is a unique string of characters generated by a mathematical function, used to represent data and ensure its integrity in cryptography and blockchain technology.

A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-length string of characters ...

A hash rate is the measure of the computational power in a proof-of-work cryptocurrency miner, pool, or network. High hash rates equal better odds of winning.

NIST has opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message ...

Such hash algorithms are ultimately one of the key security technologies for federal and public systems. The competition is NIST’s response to recent advances in the analysis of hash algorithms.
