SHA-3 STANDARD (FIPS 202)

FIPS 202, SHA-3 Standard: Permutation-Based Hash And Extendable-Output Functions

NIST published a Federal Register Notice, FRN 2014-12336, on May 28, 2014 to announce the publication of Draft FIPS 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions, and Draft Revision of the Applicability Clause of FIPS 180-4, Secure Hash Standard, and request public comments. A 90-day public comment period was provided; instructions for submitting comments were detailed in the FRN.

NIST has resolved comments received before the August 26, 2014 deadline, and announced the publication of FIPS 202, SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions in the Federal Register, FRN 80 FR 46543, on August 5, 2015. The revision of the Applicability Clause of FIPS 180-4 is also approved, that would allow the use of hash functions specified in either FIPS 180-4 or FIPS 202 for Federal applications that require a cryptographic hash function.

Examples with intermediate values for SHA-3 are available here.
