JWE decryption

JWE Decrypter Factory Service
A JWEDecrypterFactory is available as a service in your application container:
<?php
use Jose\Component\Encryption\JWEDecrypterFactory;
​
$jweDecrypterFactory = $container->get(JWEDecrypterFactory::class);
With this factory, you will be able to create the JWEDecrypter you need:
$jweDecrypter = $jweDecrypterFactory->create(['HS256']);
You can now use the JWEDecrypter as explained in the JWE Creation section.
Reminder: it is important to check the token headers. See the checker section of this documentation.
JWE Decrypter As Service
There is also another way to create a JWEDecrypter object: using the bundle configuration.
jose:
    jwe:
        decrypters:
            decrypter1:
                key_encryption_algorithms: ['A256GCMKW']
                content_encryption_algorithms: ['A256CBC-HS256']
                compression_methods: ['DEF']
                is_public: true
With the previous configuration, the bundle will create a public JWE Decrypter service named jose.jwe_decrypter.decrypter1 with selected encryption algorithms.
<?php
$jweDecrypter = $container->get('jose.jwe_decrypter.decrypter1');
Custom Tags
This feature was introduced in version 1.1.
You can add custom tags and attributes to the services you create.
jose:
    jwe:
        decrypters:
            decrypter1:
                key_encryption_algorithms: ['A256GCMKW']
                content_encryption_algorithms: ['A256CBC-HS256']
                compression_methods: ['DEF']
                tags:
                    tag_name1: ~
                    tag_name2: {attribute1: 'foo'}
JWE Loader Service
The JWELoaderFactory 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 JWELoader objects on demand.
<?php
use Jose\Component\Encryption\JWELoaderFactory;
​
$jweLoaderFactory = $container->get(JWELoaderFactory::class);
You can also create JWELoader objects as services using the configuration of the bundle.
jose:
    jwe:
        loaders:
            jwe_loader1:
                key_encryption_algorithms: ['A256GCMKW']
                content_encryption_algorithms: ['A256CBC-HS256']
                compression_methods: ['DEF']
                header_checkers: ['alg', 'enc']
                is_public: true
Or using the ConfigurationHelper.
<?php
use Jose\Bundle\JoseFramework\Helper\ConfigurationHelper;
​
...
ConfigurationHelper::addJWELoader($container, 'jwe_loader1', ['jwe_compact'], ['A256GCMKW'], ['A256CBC-HS256'], ['DEF'], ['alg', 'enc'], true);
