Decision to Revise FIPS 180-4, Secure Hash Standard (SHS)
March 07, 2023

In June 2022, NIST’s Crypto Publication Review Board initiated a review process for Federal Information Processing Standard (FIPS) 180-4, Secure Hash Standard (SHS), and received public comments.

In December 2022, the board proposed revising FIPS 180-4 and received no additional comments on that proposed decision.

NIST has decided to revise FIPS 180-4 and will revise the text to:

  1. Remove the SHA-1 specification;
  2. Add any guidance from NIST Special Publication (SP) 800-107, Recommendation for Applications Using Approved Hash Algorithms, that belongs in this document;
  3. Improve the standard’s editorial quality; and
  4. Update its references.

See the SHA-1 transition announcement.

The effort to develop the revised standard has not yet begun but will follow the typical process of releasing an initial draft for public comment. Monitor progress on CSRC News and CSRC Publications and by subscribing to email updates.
