Salve,
siccome utilizzo il seguente codice per crittografare un form in cui trasmetto informazioni a paypal:

This page uses encrypted PayPal buttons for your security.</P>

Dove i certificati li creo io tramite i comandi:
codice:
openssl genrsa -out my-prvkey.pem 1024
codice:
openssl req -new -key my-prvkey.pem -x509 -days 365 -out my-pubcert.pem
Sapete se esiste qualche servizio di hosting che ha installato SSL e che mi permette di utilizzare i certificati da me creati col codice su riportato?
