-| `secret-key-path` | The file path of the secret key, which is used to encrypt and decrypt upstream and downstream passwords. The file must contain a 64-character hexadecimal AES-256 secret key. One way to generate this key is by calculating SHA256 checksum of random data, such as <code>head -n 256 /dev/urandom \| sha256sum</code>.
