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

By understanding how cryptographic hash functions work and the critical role they play, we can better appreciate the technology that underpins modern cybersecurity.

By contrast, a hash function is a one-way encryption algorithm: once you’ve encrypted your plaintext, you can’t ever recover it from the resulting ciphertext (referred to as a hash).

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

Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist. Understanding Bitcoin is a one-way hash function should make sense because a hash ...

The cryptocurrency miner uses the hash function to solve the mathematical puzzles required to build one unit of currency. The speed at which the solution is found is the hash rate.

IOTA has just launched a new hash function, and is dishing out shares of a $220,000 bounty to anyone that can crack and improve its cryptography.

As the price climbs, so does the Bitcoin network's hash rate -- or the computing power being used to verify transactions and mine new Bitcoin. But what exactly is hashrate, and does it matter?

Cryptographer Bruce Schneier says the upcoming SHA-3 cryptographic hash algorithm is not much better than the current one ...
