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

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

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.

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 ...

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.

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.

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.

Security experts vying to have their technology selected as the next cryptographic-hash algorithm standard for the U.S. government need to submit their entries this week. Then they will have a ...
