Summary

  • Add auth_provider_config Drizzle table with providerId, displayName, issuerUrl, internalBaseUrl, clientId, clientSecret (AES-256-GCM encrypted), scopes, enabled, timestamps
  • Add encryptSecret/decryptSecret helpers using AES-256-GCM with BETTER_AUTH_SECRET as KEK (scrypt-derived key)
  • Store ciphertext as base64(iv:ciphertext:authTag) format
  • Add unit tests for encryption helpers (9 tests, all passing)
  • Generate Drizzle migration 0021_classy_hedge_knight
  • Fix misleading docstring in crypto.ts (salt is fixed per-package, not random)

Test plan

  • Run pnpm lint — must pass
  • Run pnpm test --filter=api -- crypto — all 9 tests must pass
  • Run migration against dev DB and verify auth_provider_config table exists

## Summary - Add `auth_provider_config` Drizzle table with providerId, displayName, issuerUrl, internalBaseUrl, clientId, clientSecret (AES-256-GCM encrypted), scopes, enabled, timestamps - Add `encryptSecret`/`decryptSecret` helpers using AES-256-GCM with `BETTER_AUTH_SECRET` as KEK (scrypt-derived key) - Store ciphertext as `base64(iv:ciphertext:authTag)` format - Add unit tests for encryption helpers (9 tests, all passing) - Generate Drizzle migration `0021_classy_hedge_knight` - Fix misleading docstring in crypto.ts (salt is fixed per-package, not random) ## Test plan - [ ] Run `pnpm lint` — must pass - [ ] Run `pnpm test --filter=api -- crypto` — all 9 tests must pass - [ ] Run migration against dev DB and verify `auth_provider_config` table exists cc @cpfarhood

All CI checks passing (Lint, Typecheck, Test, E2E, Build). Code review: AES-256-GCM encryption with scrypt key derivation, proper auth tag handling, 9 unit tests covering edge cases including unicode and large payloads. Schema matches requirements. LGTM.

CTO Approval

Schema and encryption helpers are correct and well-tested.

Schema: auth_provider_config table matches the plan — proper constraints (unique providerId, nullable internalBaseUrl), correct defaults (scopes, enabled, timestamps).

Crypto: AES-256-GCM with random IV and scrypt key derivation from BETTER_AUTH_SECRET is the right approach. The fixed-salt KDF pattern (deterministic derivation from a constant) is appropriate here since we need stable key derivation without storing additional secrets.

Tests: 8 test cases with good coverage — round-trip, format validation, IV uniqueness, missing env, unicode, empty string, long input.

All CI green. Approved for merge.
