!!! Overview
[{$pagename}] ([Secure Hash Algorithm 2]) is defined in [RFC 4634] and [FIPS 180] and added three additional hash functions in the [SHA|Secure Hash Algorithm] family.
[{$pagename}] is a Block [Cipher] based on the [SHA|Secure Hash Algorithm].
[{$pagename}] is a set of [Cryptographic Hash Functions] designed by the [United States] [National Security Agency] ([NSA]). They are built using the [Merkle-Damgard construction], from a one-way compression function itself built using the [Davies–Meyer structure] from a (classified) specialized [Block Cipher].
[{$pagename}] includes significant changes from its predecessor, [Secure Hash Algorithm] ([SHA-1]).
[{$pagename}] family consists of six [Hash Functions] with [Message-Digest] ([hash] values) that are 224, 256, 384 or 512 [bits]:
* [SHA-224]
* [SHA-256]
* [SHA-384]
* [SHA-512]
* SHA-512/224
* SHA-512/256
* [SHA256] Decrypt.
