Key Set Management (JWKSet)

Key Sets As Services

All these methods have the following common option:

• is_public: set the service public or private.

The key set configuration will look like as follow:

jose: # Configuration of the JWT Framework
    key_sets: # Configuration of the keys
        keyset_name: # Unique key name
            method_name: # Name of the method
                ...
                is_public: true

The key set will be available as a container service with the ID jose.key_set.keyset_name where keyset_name is the unique name of your key set. Each key set service will be an instance of the Jose\Component\Core\JWKSet class.

As any other configuration values, you can use environment variables.

From A JWKSet Object

This method will directly get a JWKSet object.

jose:
    key_sets:
        key_name:
            jwkset: # Method
                value: '{"keys":[{"kty":"oct","k":"dzI6nbW4OcNF-AtfxGAmuyz7IpHRudBI0WgGjZWgaRJt6prBn3DARXgUR8NVwKhfL43QBIU2Un3AvCGCHRgY4TbEqhOi8-i98xxmCggNjde4oaW6wkJ2NgM3Ss9SOX9zS3lcVzdCMdum-RwVJ301kbin4UtGztuzJBeg5oVN00MGxjC2xWwyI0tgXVs-zJs5WlafCuGfX1HrVkIf5bvpE0MQCSjdJpSeVao6-RSTYDajZf7T88a2eVjeW31mMAg-jzAWfUrii61T_bYPJFOXW8kkRWoa1InLRdG6bKB9wQs9-VdXZP60Q4Yuj_WZ-lO7qV9AEFrUkkjpaDgZT86w2g"},{"kty":"oct","k":"bwIAv5Nn-fo8p4LCEvM4IR9eLXgzJRs8jXCLb3xR0tDJGiZ46KheO4ip6htFKyN2aqJqlNi9-7hB6I1aLLy1IRT9-vcBoCSGu977cNAUuRLkRp7vo8s6MsxhB8WvQBDRZghV7jIYaune-3vbE7iDU2AESr8BUtorckLoO9uW__fIabaa3hJMMQIHCzYQbJKZvlCRCKWMk2H_zuS4JeDFTvyZH1skJYF_TET1DrCZHMPicw-Yk3_m2P-ilC-yidPPoVzeU8Jj3tQ6gtX3975qiQW7pt2qbgjKAuq2wsz_9hxLBtMB5rQPafFoxop7O4BklvZ9-ECcK6dfI2CAx9_tjQ"}]}'

Distant Key Sets

You can load key sets shared by a distant service (e.g. Google, Microsoft, Okta...). You must install and enable the Httplug Bundle.

When done, you have to create a client and enable the JKU Factory service by indicating the request factory service to use:

httplug: # Example of client configuration
    plugins:
        cache: # We use the cache plugin
            cache_pool: 'cache.app' # We use the PSR-6 Cache service of the application
            config:
                default_ttl: 1800 # TTL set to 30 min
    clients:
        acme:
            factory: 'httplug.factory.guzzle6'
            plugins: ['httplug.plugin.cache'] # We enable the cache plugin for that client.

jose:
    jku_factory:
        enabled: true
        client: 'httplug.client.acme' # The Httplug client
        request_factory: 'httplug.message_factory' # In general, you will use the same message factory as the one used by Httplug

Important recommendations:

• It is highly recommended to use a cache plugin for your HTTP client and thus avoid unnecessary calls to the key set endpoint.

• The connection must be secured and certificate verification should not be disabled.

From A JKU (JWK Url)

The following example will allow you tu load a key set from a distant URI. The key set must be a JWKSet object.

jose:
    key_sets:
        key_name:
            jku: # Method
                url: 'https://login.microsoftonline.com/common/discovery/keys'

From A X5U (X509 Certificates Url)

The following example will allow you tu load a key set from a distant URI. The key set must be a list of X509 certificates.

jose:
    key_sets:
        key_name:
            x5u: # Method
                url: 'https://www.googleapis.com/oauth2/v1/certs'

Shared Key Sets

It can be interesting to share your key sets through an Url. This can easily achieved by adding a dedicated controller. This controller is automatically created by the bundle.

You can enable these routes by adding the following configuration to your routing file.

# config/routes.yaml
jwkset_endpoints:
    resource: "@JoseFrameworkBundle/Resources/config/routing/jwkset_controller.php"

Then you can share your key set.

jose:
    key_sets:
        public_keyset: # The key set we want to share
            jwkset:
                value: '{"keys":[{"kty":"OKP","crv":"X25519","x":"ovuZiVcMXBN4r0VgCvJy_ChAsBv4YPJGC5w56PzndXY"},{"kty":"OKP","crv":"X25519","x":"4qyOJ4T9RkdciIn6LDxb2LdM1Ov-dtBSuj0jh6nCuyc"}]}'
    jwk_uris:
        shared_keyset:
            id: 'jose.key_set.public_keyset' # The key set service to share
            path: '/certs' # Path of the key set. Final path is hostname/route_prefix/path: https://www.foo.com/keys/certs

Now when you go to the URL http://128.0.0.1:8000/certs, you will get your key set.

Custom Tags

You can add custom tags and attributes to the services you create.

jose:
    key_sets:
        key_name:
            jku: # Method
                url: 'https://login.microsoftonline.com/common/discovery/keys'
                tags:
                    tag_name1: ~
                    tag_name2: {attribute1: 'foo'}
