The National Institute of Standards and Technology (NIST) this week opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short ...

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.

Imagine taking a block of data and turning it into a unique string of characters. Like giving it a digital nickname that never changes (unless the data does!). That’s a hash. Whether the original data ...
