A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-length string of characters ...

For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.

But competition entrants face another major challenge. While encryption algorithms rely on keeping a “key” secret from attackers, cryptographic hash functions can have no such secrets.

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

Rainbow tables are password cracking tools with origins dating back to research from the early 1980s. Here's how they work and why they haven't stood the test of time.

Because hashing algorithms works in one direction, the only way to obtain the corresponding plaintext is to guess, a process that can require large amounts of time and computational resources. The ...

SHA1 algorithm securing e-commerce and software could break by year’s end Researchers warn widely used algorithm should be retired sooner.

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 ...
