Algorithm Sunset Timer

Select your jurisdiction, sector, and algorithms in use. See which are disallowed, approaching their deadline, or still permitted under the frameworks that apply to you. RAG-rated results with hybrid guidance and recommended replacements.

  • Runs entirely in your browser: nothing is stored or transmitted
  • Covers CNSA 2.0, NIST SP 800-131A, NCSC UK, BSI, ANSSI, NIS2, and financial-sector frameworks
  • Red / Amber / Green / Grey status with deadline years and replacement algorithms
How this tool works

The Algorithm Sunset Timer cross-references your algorithm selections against a curated data matrix of regulatory framework entries. Each entry covers a specific combination of framework, jurisdiction, sector, and algorithm, and carries a status (disallowed, not recommended, acceptable, or pending), deadline information, recommended replacement, and hybrid-mode guidance.

RAG status is assigned per entry: Red for disallowed or within two years of a mandatory deadline; Amber for within five years or carrying an implicit deprecation state; Green for algorithms permitted beyond five years; Grey for entries where status is pending or classified. Where a framework covers all sectors, it will appear for any sector selection.

Results are filtered by your jurisdiction and sector, then further filtered to show only the algorithms you selected. The table groups results by framework, with each row showing the algorithm, status, deadline, replacement, and hybrid-mode position. The PDF download captures this table alongside hybrid guidance and recommended next steps.

Step 1 of 3
Step 1 of 3 — Jurisdiction

Which jurisdictions and frameworks apply to your organisation?

Select all that apply. If your organisation operates across multiple jurisdictions or is subject to more than one framework, select each one. Results will show entries from all selected frameworks.

Nothing is transmitted from your browser.

Step 2 of 3 — Sector

Which sector best describes your organisation?

Select the sector that most closely matches your primary activity. This filters sector-specific framework entries in addition to the general entries that apply to all sectors.

Step 3 of 3 — Algorithms

Which algorithms does your organisation currently use?

Select all algorithms in active use across your systems. If you are unsure, include any that may appear in your cryptographic inventory. Results will show framework entries only for the algorithms you select.

Asymmetric — Key encapsulation / encryption

Asymmetric — Signatures

Symmetric — Encryption

Need a structured PQC migration assessment?

The Algorithm Sunset Timer identifies which algorithms are at risk under your frameworks. The PQC Risk Assessment scores your organisation across all risk domains and produces an evidence base for executive decision-making.
