The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
SHA-3(Secure Hash Algorithm 3) is the latest[4]member of the Secure Hash Algorithmfamily of standards, released by NISTon August 5, 2015. [5][6][7]Although part of the same series of standards, SHA-3 is internally different from the MD5-like structureof SHA-1and SHA-2. SHA-3 is a subset of the broader cryptographic primitive family Keccak ...

A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [ 1 ] the probability of a particular n {\displaystyle n} -bit output result (hash value) for a random input string ("message") is 2 − ...
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [ 3 ][ 4 ] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
The current specification is RFC 9580 (July 2024), the successor to RFC 4880. RFC 9580 specifies a suite of required algorithms consisting of X25519, Ed25519, SHA2-256 and AES-128. In addition to these algorithms, the standard recommends X448, Ed448, SHA2-384, SHA2-512 and AES-256. Beyond these, many other algorithms are supported. PGP
Argon2. Argon2 is a key derivation function that was selected as the winner of the 2015 Password Hashing Competition. [1][2] It was designed by Alex Biryukov, Daniel Dinu, and Dmitry Khovratovich from the University of Luxembourg. [3]
FFT-based algorithms. In cryptography, SWIFFT is a collection of provably secure hash functions. It is based on the concept of the fast Fourier transform (FFT). SWIFFT is not the first hash function based on the FFT, but it sets itself apart by providing a mathematical proof of its security. It also uses the LLL basis reduction algorithm.
