Hello!
I need to create a function for trial execution (for distribution) of it: when I run a function for the first time it should writes "You may use it for 30 of 30 iterations" after one use "You may use it for 29 of 30 iterations" and so on… When it is "0 of 30" it stops to execute and writes "Your trial is over".
But the most important thing is that this function should be encripted and cannot be hacked for minutes.
Any thoughts?
