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 ...
hash HAS-160: 160 bits hash HAVAL: 128 to 256 bits hash JH: 224 to 512 bits hash LSH [19] 256 to 512 bits wide-pipe Merkle–Damgård construction: MD2: 128 bits hash MD4: 128 bits hash MD5: 128 bits Merkle–Damgård construction: MD6: up to 512 bits Merkle tree NLFSR (it is also a keyed hash function) RadioGatún: arbitrary ideal mangling ...
RadioGatún claims to have the security level of a cryptographic sponge function 19 words in size, which means the 32-bit version has the security of a 304-bit hash when looking at preimage attacks, but the security of a 608-bit hash when looking at collision attacks. The 64-bit version, likewise, has the security of a 608-bit or 1216-bit hash.
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.
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 − ...
The NIST hash function competition was an open competition held by the US National Institute of Standards and Technology (NIST) to develop a new hash function called SHA-3 to complement the older SHA-1 and SHA-2. The competition was formally announced in the Federal Register on November 2, 2007. [ 1 ] ". NIST is initiating an effort to develop ...
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]
