interface CsrfProviderInterface
deprecated
since version 2.4, to be removed in 3.0. Use {@link \Symfony\Component\Security\Csrf\CsrfTokenManagerInterface} instead.
Marks classes able to provide CSRF protection.
You can generate a CSRF token by using the method generateCsrfToken(). To this method you should pass a value that is unique to the page that should be secured against CSRF attacks. This value doesn't necessarily have to be secret. Implementations of this interface are responsible for adding more secret information.
If you want to secure a form submission against CSRF attacks, you could supply an "intention" string. This way you make sure that the form can only be submitted to pages that are designed to handle the form, that is, that use the same intention string to validate the CSRF token with isCsrfTokenValid().
Methods
string | generateCsrfToken(string $intention) Generates a CSRF token for a page of your application. | |
bool | isCsrfTokenValid(string $intention, string $token) Validates a CSRF token. |
