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

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

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.

The Proof of Work algorithm is not just a technical aspect of Bitcoin; it's a testament to the length's humanity will go to ensure trust in a trustless environment.

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 ...

Cryptographers from around the world have laid their best work on the line in a contest to find a new algorithm that will become a critical part of future communications across the Internet. The ...

Despite being something of a cryptography veteran, SHA-1 hash algorithm faces an uncertain future as OpenSSH and Libssh choose to block it.
