Check keys through a website.

[ChR0NiC]

The code that one of the cdkeys generators gave me actually worked... if only I could get the code they used...  and add it to yaesu...

What is it written in? Perhaps it can be decompiled or you could check it in Hex Workshop? It wouldn't be impossible.

Here's some code I wrote not too long ago that will check for a correct D2 Classic key or LoD key. It probably needs some work.

It was either in vb or C... looks more vb to me.

Heres a link to the one that I got a valid one from..

edit:

Have the webserver use proxies?

If somebody does do this, and then they spam invalid keys, that would spoil the proxies for everyone...

force the user to input their own proxies?

That actually might solve that problem... Good Thinking...
