This modification will allow you to use the latest encryption functions that are available in opencart 18.104.22.168 and let you install opencart 22.214.171.124 with php 7 (openssl and mysqli).
The installation is quite simple and just overwrite files.
We preferred this approach (of overwriting files) because those files are mostly used to rapidly install opencart 126.96.36.199 with the latest version of php (with openssl and mysqli) and there's no need, and no time, to install also vqmod.
This is a beta and tested only with opencart 188.8.131.52 even if it can probably work with previous versions.
