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

A mathematical formula that accepts a quantity of data and derives a number known as a "hash" or "hash value." See hash and cryptographic hash function. THIS DEFINITION IS FOR PERSONAL USE ONLY. All ...

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 ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

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 ...

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 ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...
