Fuzzing Targets

This directory contains fuzzing targets for nikic/php-fuzzer.

Quick Start

# Install php-fuzzer globally

# Run a specific target
php-fuzzer fuzz fuzzing/FuzzActivityStream.php

# Run with iteration limit
php-fuzzer fuzz fuzzing/FuzzProtocol.php --max-runs 50000

Adding New Targets

Create a new Fuzz*.php file in this directory.

<?php
declare(strict_types=1);
namespace FediE2EE\PKDServer\Fuzzing;

use PhpFuzzer\Config;

/** @var Config $config */

require_once dirname(__DIR__) . '/vendor/autoload.php';

$config->setTarget(function (string $input): void {
    // Your fuzzing logic here
    // Catch expected exceptions, let unexpected ones crash
});

Finally, add the target to CI in .github/workflows/fuzz.yml.
