Blockchain technology relies on mining algorithms, such as CryptoNight, to regulate cryptocurrency projects. Find out here what CryptoNight is and how it works.

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

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.

Proof-of-activity is the blockchain consensus algorithm that uses a combination of proof-of-work and proof-of-stake to create blocks and verify data integrity.

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 ...

SHA-1 (Secure Hash Algorithm 1) dates back to 1995 and has been known to be vulnerable to theoretical attacks since 2005.

The flaw affects the hashing algorithm, called NeuralHash, which allows Apple to check for exact matches of known child-abuse imagery without possessing any of the images or gleaning any ...
