I have an html pay now button (buy now) i have to host it on my own server and remove the protection in order for it to do what i want it to do, (a programmer who works at paypal told me what i have to do, so i can't argue with him)
now that the button works just how i want it to work, I need to encrypt it, I've been googling for a about 2 weeks or so, and i found many ways to get the job done, but i want the best and simplest way to encrypt it, because i'm new to the paypal world so i don't want to follow a tutorial that would take me a month to understand
does the standard html encrypt, do the job? I doubt that but i have to ask it anyway. If there's a simple way to do it in the server side, I'll be so happy
What do I mean by simple?
I don't mind following a long step by step tutorial to get it done, as long as it is a step by step tutorial
EDIT
Here's the code of my button (i have changed it a bit but you can see everything you need to know)
<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

</form>
As I said I had to remove the code protection so now you can see the value, using firebug or google chrome inspect element tool, or whatever and all you need is to change it, it doesn't take a hacker to do it
<input type="hidden" name="amount" value="5">
By the way my website is in php
