Hi.  
I am trying to install a paypal button on my HTML page to sell 1 or 2 items.  
I asked Paypal to generate an encrypted button and it is fine. BUT do I need to download their public certificate ? And if I don’t take it, will my button will still be recognized ? Is that absolutely necessary ?  
Thanks XXX
