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 ...

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

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 ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

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 ...

Researchers say the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates, should be urgently retired Researchers have found a new way to attack the SHA-1 hashing algorithm, ...
