Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator

<?php
// put this in your functions.php
add_filter('pre_user_query', function(&$query) {
   if($query->query_vars["orderby"] == 'rand') {
       $query->query_orderby = 'ORDER by RAND()';
   }
});

// Query will look like this:
$args = array('orderby' => 'rand', 'number' => 5);
