Parameters

Here's a list of all the parameters which can be used in this plugin's configuration:

• name or plugin

  string required

  The name of the plugin, in this case hmac-auth.

  • If using the Kong Admin API, Konnect API, declarative configuration, or decK files, the field is name.
  • If using the KongPlugin object in Kubernetes, the field is plugin.

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

• enabled

  boolean default: true

  Whether this plugin will be applied.

• config

  record required
  • hide_credentials

    boolean required default: false

    An optional boolean value telling the plugin to show or hide the credential from the upstream service. If true, the plugin strips the credential from the request (i.e. the Authorization header) before proxying it.

  • clock_skew

    number default: 300

    Clock Skew in seconds to prevent replay attacks.

  • anonymous

    string

    An optional string (consumer UUID) value to use as an anonymous consumer if authentication fails. If empty (default), the request will fail with an authentication failure 4xx. Note that this value must refer to the consumer id attribute that is internal to Kong Gateway, and not its custom_id.

  • validate_request_body

    boolean required default: false

    A boolean value telling the plugin to enable body validation.

  • enforce_headers

    array of type string

    A list of headers that the client should at least use for HTTP signature creation.

    A list of HMAC digest algorithms that the user wants to support. Allowed values are hmac-sha1, hmac-sha256, hmac-sha384, and hmac-sha512
