What is the difference between a MAC and a digital signature?

Jul 23, 2020 ... In this work, we abandon this methodology and ask whether Fiat-Shamir truly requires a cryptographic hash function. Jan 25, 2021 ... A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The ... This document describes the cryptographic hash function BLAKE2 and makes the algorithm specification and C source code conveniently available to the Internet ... Oct 1, 2019 ... Every student of electronic discovery learns about cryptographic hash functions and their usefulness as tools to digitally fingerprint files. Jan 24, 2014 ... Some hash functions do destroy information. If they map all inputs to an output of fixed size. This means there must be some inputs that map to ... Feb 4, 2017 ... A hash function H is said to be collision resistant if it is infeasible to find two values, x and y, such that x != y, yet H(x)=H(y). Jan 15, 2025 ... Is there some general principle that could be used to design a non-cryptographic hash function? One commonly adopted measure is the avalanche criterion. Cryptographic Hash Function (CHF). A cryptographic hash function (CHF) is an equation used to verify the validity of data. It has many applications, notably in ... Aug 7, 2023 ... Usage: Cryptographic and non-cryptographic hash functions also differ in their applications. Cryptographic functions are typically used in ... This page brings together everything I've written and keeps an updated table of the status of popular cryptographic hash functions.
