Compare SHA-256 vs Keccak-256 cryptographic hash functions, security, performance, and blockchain applications.

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

Three years ago, Ars declared the SHA1 cryptographic hash algorithm officially dead after researchers performed the world’s first known instance of a fatal exploit known as a “collision” on it. On ...

LAS VEGAS—Elie Bursztein, Google's lead anti-fraud researcher, began his talk here at Black Hat 2017 with an understatement: "It has been a long and interesting journey over the last few years." In ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
