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

Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

PHP got a whole lot more secure this week with the release of the 7.2 branch, a version that improves and modernizes the programming language's support for cryptography and password hashing algorithms ...

SHA1, one of the Internet’s most crucial cryptographic algorithms, is so weak to a newly refined attack that it may be broken by real-world hackers in the next three months, an international team of ...

A hash function or hash algorithm is a function for examining the input data and producing an output hash value. The process of computing such a value is known as hashing.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...
