NIST cryptographic algorithm deprecation schedule: what is approved, deprecated, and disallowed, and when
Canonical, always-current version: https://referencesource.org/nist-cryptographic-algorithm-deprecation-schedule/ Machine-readable: https://referencesource.org/nist-cryptographic-algorithm-deprecation-schedule/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-16
- Stale after: 2027-02-12 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 21
Per-algorithm status under NIST guidance for the post-quantum cryptographic transition. Each record is one algorithm or key-length configuration with its current approval status (approved, acceptable, deprecated, restricted, disallowed, legacy use), the date at which the status changes, and the recommended replacement. Drawn from three NIST publications: IR 8547 (post-quantum transition timeline), SP 800-131A Rev 2 (current algorithm status rules) and Rev 3 draft (upcoming changes), and FIPS 203/204/205 (the post-quantum replacement standards). The key deadlines: quantum-vulnerable public-key algorithms (RSA, ECDSA, ECDH, finite-field DH) deprecated after 2030, disallowed after 2035; SHA-1 and 224-bit hashes deprecated through 2030, disallowed thereafter. AES-256 and SHA-2/SHA-3 are NOT on the deprecation schedule. Answers 'when is RSA deprecated?', 'is AES-256 affected by the post-quantum transition?', 'what replaces ECDSA?', and 'what is the current NIST status of 3DES?'
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
