Vaultknox

Secret-leak protection for Hermes chats. Scans inbound messages and outbound replies for API keys, tokens, and passwords with a 28-pattern detector registry, redacts them before they reach session storage or the user, and injects safe secret-handling rules so the agent never asks for secrets in chat. Zero dependencies, fully offline detection; pairs with the optional hermes-vault CLI for encrypted storage.

Good to know before installing

Rewrites inbound user messages (regex secret redaction, may false-positive on password-like strings), injects a secret-handling prompt each conversation and rewrites assistant replies that ask for secrets; outbound replies are value-redacted with the same registry (regex-based, so a shape no detector covers passes through), with findings logged as detector name plus SHA-256 fingerprint and never the raw value. The vaultknox tool is inert unless the separate vaultknox pip package is installed, its write gate is a tool argument the model sets, and a vault policy that authorises raw consume_token returns the plaintext to the model.

How to install

  1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
    hermes plugins install vaultknox
  2. Said no? Turn it on later:
    hermes plugins enable vaultknox
  3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
