Confirmed. NIST published the transition report on October 27, 2026, and the report page dates it October 2026. The deadlines below are the ones those NIST pages attribute to and . This desk did not open the memorandum or the order.

A future quantum computer could break the math that locks email and bank records. On Tuesday, October 27, 2026, the National Institute of Standards and Technology published the timetable for moving federal systems onto encryption meant to survive that machine.1
set 2035 as the year to finish that move across federal systems. pulled the sensitive systems forward: 2030 for key establishment, and 2031 for digital signatures, on federal high-value assets and high-impact systems.1
Dustin Moody, the NIST mathematician who leads the project, said, “We lay out how certain encryption algorithms people are using today will get phased out.” The news page says the practical risk is already running. Someone can copy encrypted data now and decrypt it later, once a strong enough quantum computer exists.1
Why it matters (Estimate). Estimate. A reader does not need to own a quantum computer for this to matter. If a bank record, a hospital file, or a tax return is copied today, the person who copied it can wait until the math breaks. The years above are the government’s clock for replacing that math on federal systems, and companies that sell to those agencies will have to meet it. NIST says one schedule will not fit every system.
The report itself is , Transition to Post-Quantum Cryptography Standards. The publications page dates it October 2026 and lists Moody among the authors.2
How we know

Notes

  1. 1.National Institute of Standards and Technology, "NIST Report Provides Guidelines for Transition to Post-Quantum Cryptography Standards," October 27, 2026. https://www.nist.gov/news-events/news/2026/10/nist-report-provides-guidelines-transition-post-quantum-cryptography The page says NIST released post-quantum standards in August 2024 and has now published "Transition to Post-Quantum Cryptography Standards ()." It says "established the year 2035 as the primary target for completing the migration to PQC across federal systems." It says "accelerated this timeline, requiring federal high-value assets and high-impact systems to migrate by 2030 for key establishment and 2031 for digital signatures." Moody is quoted: "We lay out how certain encryption algorithms people are using today will get phased out." The page also quotes him: "We understand there's not one strategy that fits all use cases." It names the "harvest now, decrypt later" threat and a "cryptanalytically relevant quantum computer."
  2. 2.NIST Computer Security Resource Center, "IR 8547, Transition to Post-Quantum Cryptography Standards." https://csrc.nist.gov/pubs/ir/8547/final Date published: October 2026. Authors include Dustin Moody (NIST). The abstract says the report "supports the implementation of and , which direct federal agencies to prioritize the migration of their most sensitive systems to post-quantum cryptography."
