Call to undefined function random_bytes()

Fatal error: Call to undefined function random_bytes() in app/code/community/FireGento/Logger/Helper/Data.php on line 50

I cant see any information about what PHP version you are targeting but random_bytes() was only introduced in PHP7, Magento isnt php 7 compatible without changes.

Thanks for the report. While I strongly advise just upgrading to PHP 7 (is anyone still supporting 5.x?), if you want to add a version_compare and an alternative to fix support for older versions I think we would happily accept a PR.

You could at least list PHP 7 as your targeted version in your readme
