Hello,

I just updated from Piwigo version 2.8.0 to 2.8.1. I tried to send a notification to a group about a new album. I get the following fatal error:

Fatal error: Uncaught exception 'Exception' with message 'There is no suitable CSPRNG installed on your system' in /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/include/random_compat/random.php:185 Stack trace: #0 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/include/functions_session.inc.php(71): random_bytes(40) #1 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/include/functions_user.inc.php(1567): generate_key(30) #2 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/include/functions_mail.inc.php(541): create_user_auth_key('3', 'normal') #3 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/admin/album_notification.php(174): pwg_mail_group('2', Array, Array) #4 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/admin/album.php(88): include('/home/zirbitzko...') #5 /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/admin.php(301): include('/home/zirbitzko...') #6 {main} thrown in /home/zirbitzkogel.at/www.zirbitzkogel.at/photos/include/random_compat/random.php on line 185

Anyhow, despite of the fatal error, the members of the group got the notification email about the new album.

Best regards,

Stefan

Hi Stefan,

Can you edit file include/random_compat/random.php, line 130, replace:

Code:

            PHP_VERSION_ID >= 50307

by

Code:

            PHP_VERSION_ID >= 50303

and tell us if it works any better?

Same problemm, trying solution to change the code id to 50303 did not help

OK, I've been working on this problem yesterday. If you want to test the fix, follow the steps:

1) download srand.php on [Github] Secure-random-bytes-in-PHP file srand.php (right click "save as" on top right button "raw"). Copy file srand.php in the "include" directory of Piwigo.

2) in file include/functions_session.inc.php, replace function generate_key (line 63), by :

Code:

function generate_key($size)
{
  include_once(PHPWG_ROOT_PATH.'include/random_compat/random.php');

  try
  {
    $bytes = random_bytes($size+10);
  }
  catch (Exception $ex)
  {
    include_once(PHPWG_ROOT_PATH.'include/srand.php');
    $bytes = secure_random_bytes($size+10);
  }

  return substr(
    str_replace(
      array('+', '/'),
      '',
      base64_encode($bytes)
      ),
    0,
    $size
    );
}

Thank you very much - it fixed my problem, too.
Before I used your fix, I couldn't change user access rights for galleries anymore, but now it works.

Best regards
