The Quantum Window · Live
…
The clock started on August 13, 2024, when NIST finalized the post-quantum standards. It runs out as RSA and ECC reach their published deprecation horizon. Everything in between is the only migration window your organization will get.

The Quantum Window
39% of the published PQC migration window has already elapsed.
Both ends of this bar represent published dates: the day the standards were finalized and the year in which the draft transition guidance deprecates RSA-2048 and ECDSA P-256 for federal use. It measures a policy schedule. It is not a prediction of when quantum hardware will arrive, nor is it a statement about what has happened to your data.
Where the numbers come from
Cited, deterministic, reproducible.
No invented urgency. The window is computed from two public dates, and the percentage is pure arithmetic between them.
Window opens · 2024-08-13
NIST publishes FIPS 203 (ML-KEM), FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA) as final standards — the starting gun for global migration.
Window closes · 2030
NIST IR 8547 (draft transition guidance) deprecates 112-bit-security classical algorithms — RSA-2048, ECDSA P-256 — after 2030, and disallows them after 2035.
Elapsed % · computed live
(now − 2024-08-13) ÷ (2030-01-01 − 2024-08-13). No weighting, no editorial thumb on the scale.
Why it matters today
CISA, NSA and NIST jointly warn that harvest-now-decrypt-later collection is underway: ciphertext recorded in 2026 will be decrypted the day a cryptographically relevant quantum computer exists.
