WebJan 5, 2024 · A hash function is an algorithm that transforms data of arbitrary size into a fixed size output. The output is a ciphered text called a hash value or a digest. The main objective of a cryptographic hash function is verifying data authenticity. Hash functions often are used in passwords. WebA cryptographic hash function aims to guarantee a number of security properties. Most importantly that it's hard to find collisions or pre-images and that the output appears random.
