Need some advices about security

[DoctorSLO]

Hi.

I am trying to make autoit script that is communicating with PHP on server. I know that is this easy to hack with Microsoft loop back adapter.

I put in some math. Autoit is send some random numbers to PHP and then PHP calculate new number and send it back to autoit, and then autoit calculate it with the same way as PHP and then If PHPresult = Autoitresult = ... script running on ... else exit ...

Here is it what I do so far:

Code removed

So my question is ... is this easy to hack? If so what can I do?

Thanks for advices.

if someone wanted to they would read the data sent, then read the incoming data, figure out the calculation from the answer and the first peice of data and then it would not exit but i dont know how feasible that would be for someone to do.

Yes, but it is hard to calculate it? Or there is just simple way to do it ...

And is it possible to Encrypt the data with autoit and then decrypt with PHP?
