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

The block is assigned some information, and all of the data in the block is put through a cryptographic algorithm (called hashing). The result of hashing is a 64-digit hexadecimal number, or hash.

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

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 ...

Apple is reportedly developing a tool that would scan for child sexual abuse material (CSAM) in your iPhone photos using hashing algorithms. The system is said to be deployed on the user’s device for ...

It is time to retire SHA-1, or the Secure Hash Algorithm-1, says the US National Institute of Standards and Technology (NIST). NIST has set the date of Dec. 31, 2030 to remove SHA-1 support from all ...
