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 ...
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
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 − ...
In certain cryptographic hash functions such as RIPEMD-160, the former is less than the latter because RIPEMD-160 use two sets of parallel computation values and then combine into a single set of chaining values. ^ The maximum input size = 2length size − 1 bits. For example, the maximum input size of SHA-1 = 264 − 1 bits.
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 ...
