Usually, the same password encoder is used for all users by configuring it to apply to all instances of a specific class:
# app/config/security.yml
security:
# ...
encoders:
SymfonyComponentSecurityCoreUserUser: sha512
<!-- app/config/security.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<srv:container xmlns="http://symfony.com/schema/dic/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:srv="http://symfony.com/schema/dic/services"
xsi:schemaLocation="http://symfony.com/schema/dic/services
http://symfony.com/schema/dic/services/services-1.0.xsd"
>
<config>
<!-- ... -->
<encoder class="SymfonyComponentSecurityCoreUserUser"
algorithm="sha512"
/>
</config>
</srv:container>
// app/config/security.php
$container->loadFromExtension('security', array(
// ...
'encoders' => array(
'SymfonyComponentSecurityCoreUserUser' => array(
'algorithm' => 'sha512',
),
),
));
Another option is to use a “named” encoder and then select which encoder you want to use dynamically.
In the previous example, you’ve set the sha512 algorithm for AcmeUserBundleEntityUser.
This may be secure enough for a regular user, but what if you want your admins
to have a stronger algorithm, for example bcrypt. This can be done with
named encoders:
# app/config/security.yml
security:
# ...
encoders:
harsh:
algorithm: bcrypt
cost: 15
<!-- app/config/security.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<srv:container xmlns="http://symfony.com/schema/dic/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:srv="http://symfony.com/schema/dic/services"
xsi:schemaLocation="http://symfony.com/schema/dic/services
http://symfony.com/schema/dic/services/services-1.0.xsd"
>
<config>
<!-- ... -->
<encoder class="harsh"
algorithm="bcrypt"
cost="15" />
</config>
</srv:container>
// app/config/security.php
$container->loadFromExtension('security', array(
// ...
'encoders' => array(
'harsh' => array(
'algorithm' => 'bcrypt',
'cost' => '15'
),
),
));
This creates an encoder named harsh. In order for a User instance
to use it, the class must implement
EncoderAwareInterface.
The interface requires one method - getEncoderName - which should return
the name of the encoder to use:
// src/Acme/UserBundle/Entity/User.php
namespace AcmeUserBundleEntity;
use SymfonyComponentSecurityCoreUserUserInterface;
use SymfonyComponentSecurityCoreEncoderEncoderAwareInterface;
class User implements UserInterface, EncoderAwareInterface
{
public function getEncoderName()
{
if ($this->isAdmin()) {
return 'harsh';
}
return null; // use the default encoder
}
}
