SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA.
Strategic health authorities (SHA) were part of the structure of the National Health Service in England between 2002 and 2013. [ 1 ] [ 2 ] Each SHA was responsible for managing performance, enacting directives and implementing health policy as required by the Department of Health at a regional level.
SHA-3 (Secure Hash Algorithm 3) is the latest [4] member of the Secure Hash Algorithm family of standards, released by NIST on August 5, 2015. [5] [6] [7] Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2.
Online onboarding, i.e., digital onboarding, means onboarding training that is carried out partially or fully online. [ 27 ] [ 28 ] [ 29 ] Onboarding a new employee is a process where a new hire gets to know the company and its culture and receives the means and knowledge needed to become a productive team member.

Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [ 1 ] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
SHA-1 and SHA-2 are the hash algorithms required by law for use in certain U.S. government applications, including use within other cryptographic algorithms and protocols, for the protection of sensitive unclassified information. FIPS PUB 180-1 also encouraged adoption and use of SHA-1 by private and commercial organizations.
Sha (Cyrillic) (Ш, ш), a Cyrillic letter Śa (Indic) , a character in Brahmic scripts that originally represented a voiceless postalveolar / alveolo-palatal fricative / ʃ~ɕ / (modern pronunciation varies by language)
SHA-2 basically consists of two hash algorithms: SHA-256 and SHA-512. SHA-224 is a variant of SHA-256 with different starting values and truncated output. SHA-384 and the lesser-known SHA-512/224 and SHA-512/256 are all variants of SHA-512. SHA-512 is more secure than SHA-256 and is commonly faster than SHA-256 on 64-bit machines such as AMD64.
