I'm trying to setup the NanoSalt library on XAMPP with PHP 8.1

It return to me this error:

Fatal error: Uncaught Error: Class "MikeRow\Salt\Exception" not found in C:\xampp\htdocs\Peppe\vendor\mikerow\salt\src\NanoSalt.php:28 Stack trace: #0 C:\xampp\htdocs\Peppe\index.php(3): require_once() #1 {main} thrown in C:\xampp\htdocs\Peppe\vendor\mikerow\salt\src\NanoSalt.php on line 28

That's my index.php content:

<?php
use MikeRow\Salt\NanoSalt;
require_once "vendor/mikerow/salt/src/NanoSalt.php";

$nanoSalt = new NanoSalt();
$public_key = $nanoSalt->crypto_sign_public_from_secret_key(hex2bin("781186FB9EF17DB6E3D1056550D9FAE5D5BBADA6A6BC370E4CBB938B1DC71DA3"));
print(strtoupper($public_key->toHex()) . PHP_EOL);

?>

How can I resolve that?

  • When using composer, you don't require individual files. Instead, require the automatically generated vendor/autoload.php file. Commented Dec 30, 2021 at 14:56
  • @ChrisHaas - It didn't helped, that's new error: Fatal error: Uncaught Error: Class "MikeRow\Salt\Exception" not found in C:\xampp\htdocs\Peppe\vendor\mikerow\salt\src\NanoSalt.php:28 Stack trace: #0 C:\xampp\htdocs\Peppe\vendor\composer\ClassLoader.php(571): include() #1 C:\xampp\htdocs\Peppe\vendor\composer\ClassLoader.php(428): Composer\Autoload\includeFile('C:\\xampp\\htdocs...') #2 C:\xampp\htdocs\Peppe\index.php(5): Composer\Autoload\ClassLoader->loadClass('MikeRow\\Salt\\Na...') #3 {main} thrown in C:\xampp\htdocs\Peppe\vendor\mikerow\salt\src\NanoSalt.php on line 28 Commented Dec 30, 2021 at 15:01
  • Oh, I see now. First, that code is archived, so the author is probably not maintaining it, and I wouldn't recommend using it. You will need to hack the files, the Exception class on line 28 needs a leading "\", or you can bring it into scope with a use statement. There might be other problems of a similar nature in there, too. Commented Dec 30, 2021 at 15:05

    I'm sorry, the package you are trying to use appears to have several bugs. I would recommend not using it, or contact the author. Fixing each one here doesn't seem useful. Commented Dec 30, 2021 at 15:10
