I only don't understand what would be the benefits, to use your generator instead of well known services like bitaddress.
Anyone who uses this service as it is now will be giving that website access to their private keys of their generated paper wallets.
OP, why even make a service like this? No-one should even think about generating a paper wallet this way, even if you're not a scammer, you're teaching people to use a server-side generated paper wallet, which is bad under any circumstance.
I would take the website down and focus on making a paper wallet that is generated client-side and open up the code for inspection.
No-one should use this service or a service like this ever.
