Secure Hash Algorithms - Wikipedia
WEBSecure Hash Algorithms. 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 ...
SHA-2 - Wikipedia
WEBSHA-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. 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.
Secure Hash Algorithms | Brilliant Math & Science Wiki
WEB2 days ago · Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions.
SHA-1 - Wikipedia
WEBIn cryptography, SHA-1 ( Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160- bit (20- byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard. [3] .

WEBDefinition. The SHA (Secure Hash Algorithm) Family currently designates a family of six different hash functions: SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 [ 9 , 10] published by the American National Institute of Standards and Technology (NIST). They take variable length input messages and hash them to fixed-length outputs. Background.
Secure Hash Standard | NIST
WEBAug 4, 2015 · This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. The Applicability Clause of this standard was revised to correspond with the release of FIPS 202, SHA-3 Standard: Permutation-Based Hash …
