The date, the ballot and the plan
ISO records stage 50.20 on 21 September 2026 and no publication date. The 16 February 2027 date on this site is an estimate made for planning. The plan below is scheduled from it and is not a legal deadline.

How the estimate is made
The FDIS ballot runs eight weeks from 21 September 2026. We calculate a close on 16 November 2026. After a successful ballot the document moves to 50.60, then 60.00 and 60.60 for publication. ISO has recorded none of those three dates. The planning date is 120 days from the date this record was scoped.
An estimate is not a deadline
A date on a slide becomes a deadline in a project plan. Keep the word estimate next to it. If you need a date for a contract, use the contract's term or the regulator's date, not this page. The only confirmed dates here are the stage dates in the table above.
The dated plan
The six actions below are offsets from the estimate. They are the same actions the free check returns, filtered to the gaps your answers expose. The kit carries them as editable rows with an owner and a status column. The plan creates no legal deadline.
| Due | Action | Basis | Status |
|---|---|---|---|
| 2026-11-18 | Complete the inventory of every password-derived key and name the algorithm or store it protects. | Clause 1 turns on what the key is used for. | Open |
| 2026-12-03 | Write or refresh the parameter record for each use: function, salt, cost parameters, output length, library version, benchmark date. | Clauses 6, 7 and Annex D. | Open |
| 2026-12-18 | Decide, per use, whether to keep the current function or move to Argon2i or PBKDF2, and record the reason. | The public introduction names two functions. | Open |
| 2027-01-02 | Update the security questionnaire answers and the supplier pack with the new citations. | Buyers are asked for algorithm and parameter evidence. | Open |
| 2027-01-17 | Review the parameter floor on the weakest supported hardware and sign the residual risk. | Annex D guidance and clause 5 use decisions. | Open |
| 2027-02-02 | Check the published text against this record and re-run the test vectors. | The FDIS may differ from the DIS preview. | Open |
What would change the date
- A recorded 50.60 date after the ballot closes.
- A move to 60.00 or 60.60, which would be the first real publication signal.
- A ballot result other than approval, which would send the draft back for further work.
- A corrigendum or a revised edition after publication.
- A national adoption with its own publication date in your market.
Every one of those is a watch trigger. What the watch sends.
