<section class="phpdocumentor-description"><p>A PSR-15-compatible Middleware for stateless Double-Submit-Cookie-based CSRF protection.</p>
<p>The <code class="prettyprint">$attribute</code> property and first constructor argument sets the key by which the CSRF token
is referred to in all parameter sets (request attributes, request body parameters, cookies).</p>
<p>Generates a random token of length <code class="prettyprint">$tokenLength</code> (default 128), and stores it as an attribute
on the <code class="prettyprint">ServerRequestInterface</code>. It’s also added to the response as a cookie.</p>
<p>On requests which may modify state (methods other than HEAD, GET or OPTIONS), the request body
and request cookies are checked for matching CSRF tokens. If they match, the request is passed on
to the handler. If they do not match, further processing is halted and an error response generated
from the <code class="prettyprint">$errorResponse</code> callback is returned. Refer to the constructor argument for information
about customising the error response.</p>
