Author(s) Elaine Barker (NIST) , William Barker (NIST, Strativia) Announcement The initial draft of NIST SP 800-57 Part 1 Revision 6 is available for comment through February 5, 2026. Some of the proposed changes from Revision 5 include: Ascon, as specified in SP 800-232, and the new quantum-resistant algorithms specified in FIPS 203, 204, and 205 have been included. The keys used for both key establishment and key storage are now discussed separately. The security categories used in the PQC competition have been included, along with the quantum-resistant algorithms. The time frames for algorithm approval status have been removed and replaced with references to SP 800-131A. A section has been added to discuss keying material storage and mechanisms. See Appendix F for a more complete list of changes. Abstract This recommendation provides cryptographic key-management guidelines in three parts. Part 1 provides general guidelines and best practices for the management of cryptographic keying material, including definitions for the security services that may be provided when using cryptography and the algorithms and key types that may be employed, specifications for the protection that each type of key and other cryptographic information requires and methods for providing this protection, discussions about the functions involved in key management, and discussions about a variety of key-management issues to be addressed when using cryptography. Part 2 provides guidance on policy and security planning requirements for U.S. Government agencies. Part 3 provides guidelines for using the cryptographic features of current systems.
