JWT Configuration

You are browsing documentation for an outdated plugin version.

Configuration

This plugin is partially compatible with DB-less mode.

Consumers and JWT secrets can be created with declarative configuration.

Admin API endpoints that do POST, PUT, PATCH, or DELETE on secrets are not available on DB-less mode.

Compatible protocols

The JWT plugin is compatible with the following protocols:

grpc, grpcs, http, https

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 jwt.

  • 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
  • uri_param_names

    set of type string default: jwt

    A list of querystring parameters that Kong will inspect to retrieve JWTs.

  • cookie_names

    set of type string

    A list of cookie names that Kong will inspect to retrieve JWTs.

  • key_claim_name

    string default: iss

    The name of the claim in which the key identifying the secret must be passed. Starting with version 0.13.1, the plugin will attempt to read this claim from the JWT payload and the header, in that order.

  • secret_is_base64

    boolean required default: false

    If true, the plugin assumes the credential’s secret to be base64 encoded. You will need to create a base64-encoded secret for your Consumer, and sign your JWT with the original secret.

  • claims_to_verify

    set of type string Must be one of: exp, nbf

    A list of registered claims (according to RFC 7519) that Kong can verify as well. Accepted values: one of exp or nbf.

  • 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.

  • run_on_preflight

    boolean required default: true

    A boolean value that indicates whether the plugin should run (and try to authenticate) on OPTIONS preflight requests. If set to false, then OPTIONS requests will always be allowed.

  • maximum_expiration

    number default: 0 between: 0 31536000

    A value between 0 and 31536000 (365 days) limiting the lifetime of the JWT to maximum_expiration seconds in the future. Any JWT that has a longer lifetime is rejected (HTTP 403). If this value is specified, exp must be specified as well in the claims_to_verify property. The default value of 0 represents an indefinite period. Potential clock skew should be considered when configuring this setting.

  • header_names

    set of type string default: authorization

    A list of HTTP header names that Kong will inspect to retrieve JWTs.
