Laravel 5.2 默认的密码加密，怎么加点盐？

<code>    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }</code>

<code>    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }</code>

<code>    // Laravel 的 bcrypt 就是 
$hash = password_hash($value, PASSWORD_BCRYPT, ['cost' => 10]);</code>

<code>$hash = password_hash('password',PASSWORD_BCRYPT,['cost' => 10]);
echo $hash;
// 比如我这次算的是
// $hash = '$2y$10$DyAJOutGjURG9xyKgAaCtOm4K1yezvgNkxHf6PhuLYBCENk61bePm';</code>

<code>if (password_verify('password', $hash)) {
    echo '密码正确.';
} else {
    echo '密码错误!';
}

// 原理是: 

if ($hash === crypt('password', '$2y$10$DyAJOutGjURG9xyKgAaCtO')) {
    echo '密码正确.';
} else {
    echo '密码错误!';
}
</code>
