DEPRECATED in favor of `psr7-sessions/storageless` 5.0.0+ ========================================================= [](#deprecated-in-favor-of-psr7-sessionsstorageless-500) Please note that this package is **DEPRECATED**. Since [`psr7-sessions/storageless` 5.0.0](https://github.com/psr7-sessions/storageless/releases/tag/5.0.0), the generated cookies are CSRF-resistant by default for unsafe HTTP methods (`POST`/`PUT`/`DELETE`/`PATCH`/etc.), so the usage of this package is no longer needed. You can still install `ocramius/psr7-csrf`, but since there is no practical need for it, it is not necessary to do so. ### What is this about? [](#what-is-this-about) Instead of storing tokens in the session, PSR7Csrf simply uses JWT tokens, which can be verified, signed and have a specific lifetime on their own. This storage-less approach prevents having to load tokens from a session or from a database, and simplifies the entire UI workflow: tokens are valid as long as their signature and expiration date holds. ### Installation [](#installation) ``` composer require ocramius/psr7-csrf ``` ### Usage [](#usage) The simplest usage is based on defaults. It assumes that you have a configured PSR-7 compatible application that supports piping middlewares, and it also requires you to run [PSR7Session](https://github.com/Ocramius/PSR7Session). In a [`zendframework/zend-expressive`](https://github.com/zendframework/zend-expressive)application, the setup would look like the following: ``` $app = \Zend\Expressive\AppFactory::create(); $app->pipe(\PSR7Session\Http\SessionMiddleware::fromSymmetricKeyDefaults( 'mBC5v1sOKVvbdEitdSBenu59nfNfhwkedkJVNabosTw=', // replace this with a key of your own (see PSR7Session docs) 1200 // 20 minutes session duration )); $app->pipe(\PSR7Csrf\Factory::createDefaultCSRFCheckerMiddleware()); ``` This setup will require that any requests that are not `GET`, `HEAD` or `OPTIONS` contain a `csrf_token` in the request body parameters (JSON or URL-encoded). You can generate the CSRF token for any form like following: ``` $tokenGenerator = \PSR7Csrf\Factory::createDefaultTokenGenerator(); $app->get('/get', function ($request, $response) use ($tokenGenerator) { $response ->getBody() ->write( '' . '' . '' . '' ); return $response; }); $app->post('/post', function ($request, $response) { $response ->getBody() ->write('It works!'); return $response; }); ``` ### Examples [](#examples) ``` composer install # install at the root of this package first! cd examples composer install php -S localhost:9999 index.php ``` Then try accessing `http://localhost:9999`: you should see a simple submission form. If you try modifying the submitted CSRF token (which is in a hidden form field), then the `POST` request will fail. ### Known limitations [](#known-limitations) Please refer to the [known limitations of PSR7Session](https://github.com/Ocramius/PSR7Session/blob/master/docs/limitations.md). Also, this component does *NOT* prevent double-form-submissions: it merely prevents CSRF attacks from third parties. As long as the CSRF token is valid, it can be reused over multiple requests. ### Contributing [](#contributing) Please refer to the [contributing notes](CONTRIBUTING.md). ### License [](#license) This project is made public under the [MIT LICENSE](LICENSE). ### Health Score 36 — LowBetter than 79% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity31 Limited adoption so far Community16 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor1 Top contributor holds 93.1% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
