Summary

The report describes how NIST intends to guide the move from quantum-vulnerable cryptographic algorithms to post-quantum standards for digital signatures and key establishment (FIPS 203, 204 and 205). It lists the existing standards affected, the algorithms that will replace them and the timeline: current public-key algorithms will be deprecated after 2030 and disallowed after 2035. It makes clear that this window serves lower-risk systems and does not change the earlier deadlines set for the most sensitive federal systems by Executive Order 14412 and OMB memorandum M-26-15. It is aimed at vendors, standards bodies and agencies to speed up the adoption of post-quantum cryptography.

Notes
Final version published on 27 October 2026, replacing the draft of 12 November 2024. The transition dates concern NIST standards; federal agencies are also bound by the earlier deadlines of Executive Order 14412 (2030 for key establishment and 2031 for signatures in the most sensitive systems) and by TLS 1.3 support by 2 January 2030.
