JWE Decrypter Factory Service
A JWEDecrypterFactory is available as a service in your application container:
1
<?php
2
use Jose\Component\Encryption\JWEDecrypterFactory;
3
​
4
$jweDecrypterFactory = $container->get(JWEDecrypterFactory::class);
Copied!
With this factory, you will be able to create the JWEDecrypter you need:
1
$jweDecrypter = $jweDecrypterFactory->create(['HS256']);
Copied!
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.
1
jose:
2
    jwe:
3
        decrypters:
4
            decrypter1:
5
                key_encryption_algorithms: ['A256GCMKW']
6
                content_encryption_algorithms: ['A256CBC-HS256']
7
                compression_methods: ['DEF']
8
                is_public: true
Copied!
With the previous configuration, the bundle will create a public JWE Decrypter service named jose.jwe_decrypter.decrypter1 with selected encryption algorithms.
1
<?php
2
$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.

    jwe:

        decrypters:
4
            decrypter1:
5
                key_encryption_algorithms: ['A256GCMKW']
6
                content_encryption_algorithms: ['A256CBC-HS256']
7
                compression_methods: ['DEF']
8
                tags:
9
                    tag_name1: ~
10
                    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.
1
<?php
2
use Jose\Component\Encryption\JWELoaderFactory;
3
​
4
$jweLoaderFactory = $container->get(JWELoaderFactory::class);
Copied!
You can also create JWELoader objects as services using the configuration of the bundle.

jose:
2
    jwe:
3
        loaders:
4
            jwe_loader1:
5
                key_encryption_algorithms: ['A256GCMKW']
6
                content_encryption_algorithms: ['A256CBC-HS256']
7
                compression_methods: ['DEF']
8
                header_checkers: ['alg', 'enc']
9
                is_public: true
Copied!
Or using the ConfigurationHelper.
1
<?php
2
use Jose\Bundle\JoseFramework\Helper\ConfigurationHelper;
3
​
4
...
5
ConfigurationHelper::addJWELoader($container, 'jwe_loader1', ['jwe_compact'], ['A256GCMKW'], ['A256CBC-HS256'], ['DEF'], ['alg', 'enc'], true);
Copied!
