NIST has released a draft revision of Special Publication (SP) 800-185, SHA-3 Derived Functions: cSHAKE, KMAC, TupleHash, and ParallelHash. Revision 1 introduces streaming interfaces for extendable-output function (XOF) computations, which allow applications to process input and request output incrementally without knowing the total input or output length in advance.

The public comment period is open through December 7, 2026. See the publication details for additional information.
