Phase 2 of CODE_AUDIT §1.2 — live adoption of the Argon2id foundation.
Verified at runtime: a rotated account shows hash_algo=argon2id-v2 with
argon2_m=19456,t=2,p=1 in vault.db.
Server (never runs Argon2 — zero-knowledge, only stores/echoes params):
- DB: users.argon2_m/t/p columns (default 0 = PBKDF2).
- PM.Handler.Auth: HASH_ALGO_ARGON2 + param bounds, ReadArgon2Params /
AppendArgon2Params helpers. /register and /change-master-password accept
hashAlgo='argon2id-v2' + argon2:{m,t,p} and persist them; /login/challenge
echoes them. Verify path (VerifierToStoredHash/CheckVerifier) is
KDF-agnostic — the 64-hex verifier is SHA256-wrapped as for any -v2 scheme.
Client (app.js):
- state.argon2Params, cached from the challenge and persisted to
sessionStorage + the quick-unlock / PIN cold-start blobs (so a cold-started
session can still derive-from-password for reauth/rotation).
- Register + master-pw rotation derive with argon2id-v2 + ARGON2_DEFAULT_PARAMS
(OWASP m=19MiB,t=2,p=1) and send the params. Rotation re-encrypts the whole
vault under the new Argon2 key (natural migration point). Existing accounts
stay PBKDF2 until they rotate.
- Params threaded through every derive-from-password site (login, reauth,
recovery setup, change-pw current verifier). Cold-start verifier-from-raw-key
paths need no params (isDecoupledVerifierAlgo handles the -v2 wrap).
Tests: +2 param-contract tests (register<->login determinism, param
sensitivity). 42/42. Assets rebuilt to embed js/argon2.js.
Docs: CLAUDE.md auth-hash section rewritten (4 markers); CODE_AUDIT §1.2 +
table + plan marked done.
