We are launching a WordPress eCommerce plugin and we have a "paid" option and need to encrypt the relevant file that's in our free version (and has to be).
We have used ion cube, but both proved a pain for maybe 10% of our users, (ioncube not activated or available on some servers). That 10% was enough to search out a simpler easier solution.
So i thought i would try here for ideas / suggestions.
We do not need the end user to decrypt at any time, just need this file working, but unusable outside of our software.
Thanks in advance.
