For WordPress wp_nonce_field and wp_verify_nonce field to verify.

https://codex.wordpress.org/Function_Reference/wp_nonce_field

Form field like:

<form method="post">  
   <?php wp_nonce_field('name_of_my_action','name_of_nonce_field'); ?>
</form>

In action file

<?php
if ( empty($_POST) || !wp_verify_nonce($_POST['name_of_nonce_field'],'name_of_my_action') )
{
   print 'Sorry, your nonce did not verify.';
   exit;
}
else
{
   // process form data
}
