PHP Csrf Tokens

PHP Csrf Tokens is a simple session & cookie based csrf token generator and verifier.

Installation

Via Composer

$ composer require steveclifton/phpcsrftokens

Usage

For ease of use, all PHP Csrf Tokens methods have been made static to make generation and verification as simple as possible.

Following the OWASP guidelines, the verifyToken() method does not reset the tokens after each request, enabling double submission of the form.

Requires superglobal $_SESSION to be set.

<?php

require_once __DIR__ /*Path To File*/;

use steveclifton\phpcsrftokens\Csrf;

session_start();

if (!empty($_GET['a'])) {
	echo '<pre>' . print_r($_POST, true) . '</pre>';
	echo 'Verification has been : ' . (Csrf::verifyToken('home') ? 'successful' : 'unsuccessful');
}

?>

<!DOCTYPE html>
<html>
<head><title>Test Script</title></head>
<body>
	<form action="?a=submit" method="POST">
		<?php echo Csrf::getInputToken('home') ?>
		<input type="text" name="name" placeholder="Test Input"><br>
		<button>Submit!</button>
	</form>
