pfft, thats not a key see.
thats not reverse engineering it either.
I gave u the source dork. ;]
The only way you'd be able to reverse engineer it would to have the php source code:
It becomes: 5cc9-d98a-0d41-c921-e21b
http://126.96.36.199/test.php?action=v ... -c921-e21b
To prove that it actually works:
http://188.8.131.52/test.php?action=v ... -a921-e21b
Thats an invalid key.
you can use upper or lower case:
By the way, random keygens aren't really useful as anyone could just generate a key the way you did and bam get one.
But if you want a random keygen:
http://184.108.40.206/rkg.php?a=10&c=8& ... rated_keys
a = Amount
an = Array Name; Default: keys
c = Characters inbetween the "-"
s = Sections there are in the key such as 1-2-3-4 is default.
5 would be: 1-2-3-4-5 sections.
Basically I've made it print out an php array for you. But until then its php. To check to see if a key is right use this: (thinking that you used $keys to hold the array of keys that is)
$input = $_GET['key'];
echo "Valid key!";
echo "Invalid key!!!";
