NIST has released its final roadmap, NIST IR 8547, for transitioning to post-quantum cryptography (PQC) standards, with federal agencies facing binding deadlines to adopt PQC for key establishment by December 31, 2030, and digital signatures by December 31, 2031. Classical public-key algorithms will be deprecated after 2030 and disallowed after 2035. The report emphasizes the urgency of PQC adoption due to "Harvest Now, Decrypt Later" attacks and provides guidelines for hybrid schemes during the transition.
