Announcing Approval of Federal Information Processing Standard (FIPS) 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions, and Revision of the Applicability Clause of FIPS 180-4, Secure Hash Standard
August 05, 2015

This notice announces the Secretary of Commerce's approval of Federal Information Processing Standard (FIPS) 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions, and a revision of the Applicability Clause of FIPS 180-4, Secure Hash Standard. FIPS 202 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 of FIPS 180-4 approves the use of hash functions specified in either FIPS 180-4 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.
