What does hash algorithm actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

Cryptographic hash functions are mathematical functions that are often used with cryptocurrency. Find out in this guide how they work and what their role is.

Friday February 24, 2017 Reuters The algorithm, known as Secure Hash Algorithm 1 or SHA-1, is currently used to verify the integrity of digital files and signatures.

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.

Who Broke the SHA1 Algorithm (And What Does It Mean for Bitcoin)? The SHA1 encryption algorithm was recently 'broken' by researchers at Google and CWI Amsterdam. Should the bitcoin world worry?

Perceptual hash functions aim to imitate human perception by focusing on the types of features that drive human sight and hearing.

For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.

A target hash sets the difficulty for cryptocurrency mining using a proof-of-work (PoW) blockchain system.
