What SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions requires
This Standard specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data, based on the KECCAK algorithm selected by NIST. The SHA-3 family consists of four cryptographic hash functions (SHA3-224, SHA3-256, SHA3-384, and SHA3-512) and two extendable-output functions or XOFs (SHAKE128 and SHAKE256). These functions supplement the SHA-1 and SHA-2 families specified in FIPS 180-4, providing resilience against future advances in hash function analysis through fundamentally different design principles. This standard is applicable to all Federal departments and agencies for protecting sensitive unclassified information. The core obligation is that either this Standard or FIPS 180 must be implemented wherever a secure hash algorithm is required for Federal applications, including as a component within other cryptographic algorithms and protocols. Implementations may be in software, firmware, hardware, or any combination thereof, but only implementations validated by the Cryptographic Algorithm Validation Program (CAVP) will be considered compliant. This standard may also be adopted and used by non-Federal Government organizations.
