JWS Verifier Factory Service
A JWSVerifierFactory is available as a service in your application container:
1
<?php
2
use Jose\Component\Signature\JWSVerifierFactory;
3
​
4
$jwsVerifierFactory = $container->get(JWSVerifierFactory::class);
Copied!
With this factory, you will be able to create the JWSVerifier you need:
1
$jwsVerifier = $jwsVerifierFactory->create(['HS256']);
Copied!
You can now use the JWSVerifier as explained in the JWS Creation section.
Reminder: it is important to check the token headers. See the checker section of this documentation.
JWS Verifier As Service
There is also another way to create a JWSVerifier object: using the bundle configuration.
1
jose:
2
    jws:
3
        verifiers:
4
            verifier1:
5
                signature_algorithms: ['HS256', 'RS256', 'ES256']
6
                is_public: true
Copied!
With the previous configuration, the bundle will create a public JWS Verifier service named jose.jws_verifier.verifier1 with selected signature algorithms.
1
<?php
2
$jwsVerifier = $container->get('jose.jws_verifier.verifier1');
Copied!
Custom Tags
This feature was introduced in version 1.1.
You can add custom tags and attributes to the services you create.
1
jose:
2
    jws:
3
        verifiers:
4
            verifier1:
5
                signature_algorithms: ['HS256', 'RS256', 'ES256']
6
                tags:
7
                    tag_name1: ~
8
                    tag_name2: {attribute1: 'foo'}

JWS Loader Service
This feature was introduced in version 1.1.
The JWSLoaderFactory is available as a public service. You can retrieve it using the container or inject it into your services. It will help you to create JWSLoader objects on demand.
1
<?php
2
use Jose\Component\Signature\JWSLoaderFactory;
3
​
4
$jwsLoaderFactory = $container->get(JWSLoaderFactory::class);
Copied!
You can also create JWSLoader objects as services using the configuration of the bundle.
1
jose:
2
    jws:
3
        loaders:
4
            jws_loader1:
5
                serializers: ['jws_compact']
6
                signature_algorithms: ['HS256']
7
                header_checkers: ['alg']
8
                is_public: true
Copied!
Or using the ConfigurationHelper.
1
<?php
2
use Jose\Bundle\JoseFramework\Helper\ConfigurationHelper;
3
​
4
...
5
ConfigurationHelper::addJWSLoader($container, 'jws_loader1', ['jws_compact'], ['HS256'], ['alg'], true);
Copied!
