 * Also WRONG
    mcrypt error ‘The required module, mcrypt, is not installed, or has
   been disabled.‘ My PHP version is 7.2.13. mcrypt module was deprecated in PHP
   7.1, and removed in PHP 7.2.0. As a matter of fact this module was never required
   in PHP.

 * Keep in mind that this plugin has backwards compatible code all the way back 
   to php 5.2.

 * Hiya,
 * As [@pidengmor](https://wordpress.org/support/users/pidengmor/) mentioned, the
   warnings from the original poster are related to backwards compatible code for
   older WordPress installs. There’s unfortunately no way to avoid them throwing
   errors when doing a static code analysis.
 * As for your remark [@companyv](https://wordpress.org/support/users/companyv/),`
   mcrypt` isn’t required by PHP; it’s required by WordPress, and should only show
   up if `libsodium` (the better alternative) is missing for some reason (this was
   included in PHP from version 7.2.0 and onwards, as you say, but it is possible
   to build PHP without it, which some hosts have done in the past, this is why 
   the checks are in place).
 * If you believe this latter to be in error, I’d appreciate a new topic to cove
   it, so as not to hijack the original topic from its creator 🙂
