!!! Overview
[{$pagename}] is [Federal Information Processing Standard] that specifies [hash] [algorithms] that can be used to generate [Message-Digest]. 


The [Message-Digest] are used to detect whether [messages] have been changed (i.e possess [Integrity]) since the [Message-Digest] were generated. The Applicability Clause of this standard was revised to correspond with the release of [FIPS 202], "[SHA-3] Standard: Permutation-Based Hash and Extendable-Output Functions," which specifies the [SHA-3] family of [hash] functions, as well as mechanisms for other [cryptographic] functions to be specified in the future. 


The revision to the Applicability Clause approves the use of hash functions specified in either [{$pagename}]-4 or [FIPS 202] when a secure hash function is required for the protection of sensitive, unclassified information in Federal applications, including as a component within other [cryptographic] [algorithms] and [protocols].
