Setting JWT_SECRET via environment variable was broken by design:
the admin panel rotation updates the in-memory binding and persists
the new value to data/.jwt_secret, but an env var would silently
override it on the next restart, reverting the rotation.
The server now always loads JWT_SECRET from data/.jwt_secret
(auto-generating it on first start), making the file the single
source of truth. Rotation is handled exclusively through the admin
panel.
- config.ts: drop process.env.JWT_SECRET fallback and
JWT_SECRET_IS_GENERATED export; always read from / write to
data/.jwt_secret
- index.ts: remove the now-obsolete JWT_SECRET startup warning
- .env.example, docker-compose.yml, README: remove JWT_SECRET entries
- Helm chart: remove JWT_SECRET from secretEnv, secret.yaml, and
deployment.yaml; rename generateJwtSecret → generateEncryptionKey
and update NOTES.txt and README accordingly
Introduces a dedicated ENCRYPTION_KEY for encrypting stored secrets
(API keys, MFA TOTP, SMTP password, OIDC client secret) so that
rotating the JWT signing secret no longer invalidates encrypted data,
and a compromised JWT_SECRET no longer exposes stored credentials.
- server/src/config.ts: add ENCRYPTION_KEY (auto-generated to
data/.encryption_key if not set, same pattern as JWT_SECRET);
switch JWT_SECRET to `export let` so updateJwtSecret() keeps the
CJS module binding live for all importers without restart
- apiKeyCrypto.ts, mfaCrypto.ts: derive encryption keys from
ENCRYPTION_KEY instead of JWT_SECRET
- admin POST /rotate-jwt-secret: generates a new 32-byte hex secret,
persists it to data/.jwt_secret, updates the live in-process binding
via updateJwtSecret(), and writes an audit log entry
- Admin panel (Settings → Danger Zone): "Rotate JWT Secret" button
with a confirmation modal warning that all sessions will be
invalidated; on success the acting admin is logged out immediately
- docker-compose.yml, .env.example, README, Helm chart (values.yaml,
secret.yaml, deployment.yaml, NOTES.txt, README): document
ENCRYPTION_KEY and its upgrade migration path
