§ 01
Credentials and secrets
Broker keys and API tokens are encrypted before they ever touch the database. They are decrypted on-demand for a single request and never logged.
- Fernet symmetric encryption with PBKDF2-SHA256 key derivation.
- Encryption key lives in environment configuration, not in the codebase.
- Legacy-key migration runs transparently on read; rotation is supported.
- Public routes never accept, return, or log credentials of any kind.
