If you are using PHP >= 5.5 then you can do hash verification by using password_verify() function. Internally laravel uses the same function while doing Hash::check().
For example:
$hashedPassword = '$2y$10$XEq0uTegk/KlkuOR.xMKfenIH9XpstjTau2qBrQoGiuyGgd/NHXjO';
$password = 'password';
if(password_verify($password, $hashedPassword))
echo 'Password is valid!';
else
echo 'Invalid password.';
