Plan sect.5: parola RAR vine per-cerere, stocata CRIPTATA in submission pana la primul login reusit pe cont, apoi stearsa; JWT 30h acopera restul. - app/crypto.py: Fernet, cheie din AUTOPASS_creds_key (nesetata -> efemera la runtime, creds nu supravietuiesc restartului). encrypt/decrypt_creds. - schema + migrare: submissions.rar_creds_enc (creds criptate). - ingestie: cripteaza rar_credentials, le lipeste de fiecare submission nou. Niciodata in clar in DB. - worker: AccountSessions (login per-cont cu creds decriptate, cache JWT in memorie, sterge creds-urile contului dupa primul login + refresh nomenclator). 401 creds gresite -> error fara retry; token expirat -> invalidare + requeue; fara creds (restart) -> requeue "indisponibile" (ROAAUTO re-trimite). claim_one intoarce account_id + creds_enc; recover_orphans filtrabil pe cont. - requirements: cryptography==46.0.5. Nota: refresh nomenclator e acum lazy la primul login per-cont (nu la pornire); seed-ul fallback acopera editorul offline. 10 teste noi (tests/test_creds_delivery.py). 95 pass total.

"""Criptare simetrica pentru credentialele RAR efemere (zero-storage at rest).

Plan sect. 5: parola RAR vine per-cerere, se stocheaza CRIPTATA in submission
|
|
pana la primul login reusit pentru cont, apoi se sterge. JWT (30h) acopera
|
|
restul trimiterilor. Cheia traieste doar in `AUTOPASS_creds_key` (env), niciodata
|
|
in cod sau in DB.
|
|
|
|
Daca `AUTOPASS_creds_key` nu e setat, generam o cheie EFEMERA la prima folosire:
|
|
creds criptate NU supravietuiesc unui restart (acceptabil — modelul e efemer,
|
|
ROAAUTO re-trimite). Pentru productie seteaza o cheie persistenta (vezi README/deploy).
