Algorithm Manager Factory Service

The Symfony Bundle provides an Algorithm Manager Factory service. The available algorithms depends on the components installed on your application.

<?php
use Jose\Component\Core\AlgorithmManagerFactory;
$algorithmManagerFactory = $container->get(AlgorithmManagerFactory::class);
$algorithmManager = $algorithmManagerFactory->create(['RS256', 'HS512']);

Custom Algorithm

This factory handles all algorithms services tagged with jose.algorithm.

Example:

services:
Acme\Bundle\Algorithm\FooAlgorihtm:
tags:
- {'name': 'jose.algorithm', 'alias': 'FOO'}

Your algorithm will be available through the algorithm manager factory service and the alias FOO.

PBES2-* Algorithms

When installed, the PBES2-* algorithms available throught the algorithm manager factory. They have the default configuration i.e. salt size = 62 bits and count = 4096. If these values does not fit on your needs, you can create a new algorithm service with your own values:

services:
Jose\Component\Encryption\Algorithm\KeyEncryption\PBES2HS256A128KW:
arguments:
- 128 # salt size
- 10240 # counts
tags:
- {'name': 'jose.algorithm', 'alias': 'Ultra-Secured PBES2-HS256+A128KW'}

You can now use your custom alias:

$algorithmManager = $algorithmManagerFactory->create(['Ultra-Secured PBES2-HS256+A128KW']);
