Overview

Inspects Rails credentials configuration WITHOUT revealing any decrypted value. Returns file presence, master-key source (file vs env), per-environment encrypted files, and top-level key names. Covers RAILS_NERVOUS_SYSTEM.md ยง30 (Credentials, Secrets, Encrypted files).

Safety contract:

  • Values are NEVER returned. Top-level keys are listed only when the credentials decrypt successfully; the values behind each key stay on the user's machine.
  • Master-key contents are NEVER read. Only presence (file exists vs RAILS_MASTER_KEY set) is reported.
