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 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.

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

Rainbow tables are password cracking tools with origins dating back to research from the early 1980s. Here's how they work and why they haven't stood the test of time.

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

But competition entrants face another major challenge. While encryption algorithms rely on keeping a “key” secret from attackers, cryptographic hash functions can have no such secrets.

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.

SHA1 algorithm securing e-commerce and software could break by year’s end Researchers warn widely used algorithm should be retired sooner.

The MD5 password hash algorithm is "no longer considered safe" by the original software developer, a day after the leak of more than 6.4 million hashed LinkedIn passwords.
