JWS verification

JWS Verifier Factory Service
A JWSVerifierFactory is available as a service in your application container:
<?php
use Jose\Component\Signature\JWSVerifierFactory;
​
$jwsVerifierFactory = $container->get(JWSVerifierFactory::class);
With this factory, you will be able to create the JWSVerifier you need:
$jwsVerifier = $jwsVerifierFactory->create(['HS256']);
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.
jose:
    jws:
        verifiers:
            verifier1:
                signature_algorithms: ['HS256', 'RS256', 'ES256']
                is_public: true
With the previous configuration, the bundle will create a public JWS Verifier service named jose.jws_verifier.verifier1 with selected signature algorithms.
<?php
$jwsVerifier = $container->get('jose.jws_verifier.verifier1');
Custom Tags
You can add custom tags and attributes to the services you create.
jose:
    jws:
        verifiers:
            verifier1:
                signature_algorithms: ['HS256', 'RS256', 'ES256']
                tags:
                    tag_name1: ~
                    tag_name2: {attribute1: 'foo'}
JWS Loader Service
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.
<?php
use Jose\Component\Signature\JWSLoaderFactory;
​
$jwsLoaderFactory = $container->get(JWSLoaderFactory::class);
You can also create JWSLoader objects as services using the configuration of the bundle.
jose:
    jws:
        loaders:
            jws_loader1:
                serializers: ['jws_compact']
                signature_algorithms: ['HS256']
                header_checkers: ['alg']
                is_public: true
Or using the ConfigurationHelper.
<?php
use Jose\Bundle\JoseFramework\Helper\ConfigurationHelper;
​
...
ConfigurationHelper::addJWSLoader($container, 'jws_loader1', ['jws_compact'], ['HS256'], ['alg'], true);
