# secrets tune

The `secrets tune` command tunes the configuration options for the secrets
engine at the given PATH. The argument corresponds to the PATH where the secrets
engine is enabled, not the TYPE!

## Examples

Tune the default lease for the PKI secrets engine:

```shell-session
$ vault secrets tune -default-lease-ttl=72h pki/
```

Specify multiple audit non-hmac request keys:

```shell-session
$ vault secrets tune -audit-non-hmac-request-keys=value1 -audit-non-hmac-request-keys=value2 pki/
```

## Usage

The following flags are available in addition to the [standard set of
flags](/docs/commands) included on all commands.

- `-audit-non-hmac-request-keys` `(string: "")` - Key that will not be HMAC'd
  by audit devices in the request data object. Note that multiple keys may be
  specified by providing this option multiple times, each time with 1 key.

- `-audit-non-hmac-response-keys` `(string: "")` - Key that will not be HMAC'd
  by audit devices in the response data object. Note that multiple keys may be
  specified by providing this option multiple times, each time with 1 key.

- `-default-lease-ttl` `(duration: "")` - The default lease TTL for this secrets
  engine. If unspecified, this defaults to the Vault server's globally
  configured default lease TTL, or a previously configured value for the secrets
  engine.

- `-max-lease-ttl` `(duration: "")` - The maximum lease TTL for this secrets
  engine. If unspecified, this defaults to the Vault server's globally
  configured maximum lease TTL, or a previously configured value for the secrets
  engine.
