| This one is different from the others in terms of algorithm, ui, and language.

Heh this one runs cause its VB.NET from the looks of it. I decompiled your prog, which I know is not the objective here, but yea.. I will attempt to write the keygen in a little bit when I get the free time, just going over a few things for others if they want help with it..
Name has to be over 4 characters long.
Email has to be over 7 characters long.
Serial key must be 18 characters long?
The name check is done using the Name and the Serial.
The email check is done using the Email and the Serial.
I have the full source to your functions as well, just gotta reverse them a bit to make the keygen. Like I said, will attempt it 
-- Edit ---
Eh.. ok I'm not good with VB.NET, I hate it to be honest, so I'm not sure what some of the functions do for it. So yea.. can't get past the first few parts of doing this

| I hate vb and vb.net; it's done in c#. I usually re-write it to c++, but I didn't feel like dealing with the Win32 API today.

Ah, looks like VB.NET, I haven't touched C# since the RunUO days of Ultima Online >.>
And yea, C++ gets annoying for small projects.

That's probably because you're decompiling the compiled .net bytecodes. All of the MS .net languages compile into CIL bytecodes. The bytecode can then be decompiled into any of the MS .net languages; most of the time it's only a matter of chaning a setting on your decompiler, or getting another decompiler.

I just used Salamanders online decompiler to take a look. I'm not much of a keygen/patcher person. I know how to do some things, not much though in this field. Just been peeking around in here to see if I could learn anything. Thanks for the tip about .NET though, I stay away from it personally, can't stand it >.>

The easiest way to make a keygenerater for this would be to create a brute force.
Since the serial is not actually ever being compared, you would dump the checkname and checkemail into a program and have it loop until it turns 1 (which is valid) then have it loop in the next.
Don't have a compiler on this computer but I'll throw something together tomorrow.

name checking algo:
| Code: | for (int i = 0; i < 4; i++)
{
chArray3[i] = chArray[i];
num = chArray3[i];
num *= 294873 + i;
num *= 9142;
num = num % 10;
num += 48;
chArray3[i] = (char) num;
chArray3[i] = (char) (chArray3[i] ^ chArray[3]);
chArray3[i] = chArray3[i] >> ((1 + i) & 31);
num = chArray3[i];
num = num % 10;
num += 48;
chArray3[i] = (char) num;
} |
charray is the entered name
charray2 is the entered key
heres the email checking algo:
| Code: | for (int i = 0; i < 7; i++)
{
numArray[i] = chArray2[i];
numArray[i] -= 48;
}
for (int j = 0; j < 7; j++)
{
num = chArray[j];
num *= numArray[j];
num *= 198187 * (j + 3);
num = num % 10;
num += 48;
chArray4[j] = (char) num;
chArray4[j] = (char) (chArray4[j] & chArray[6]);
chArray4[j] = chArray4[j] << ((1 + j) & 31);
num = chArray4[j];
num = num % 10;
num += 48;
chArray4[j] = (char) num;

making keygen? umm... ill try self keygening it.
oh wait lol i forgot i dont have c installed...
well i can easly make a keygen for this 1, but ill leave it to u guys.

That's one thing I hate about the .Net; it can be decompiled. At least I know there is a high possibility that someone will make a keygen for this  .

lawl ok u didnt say it cant be keygenned but y brute force and y loop? u can easly make a keygen that will generate name and key from email, or email and name from key, or key and email from name.

Do you understand what a bruteforce keygen even is?
It's still a keygenerator, it just cycles through the possibilities. Dump the routine, enter in your name and have it cycle through the algorithm until it returns valid, then you have the valid key. If I have the validation code he uses, why would i give a crap about reserving it. On a normal computer it would take probably an extra few seconds to even get the key opposed to generating it from scratch.
Why kill a fly with a bazooka when you can kill it with a fly swatter?
Every tool has it's uses.

a. now i know whats a bruteforce keygen
b. still, it doesnt need to cycle through the code. theres a calculation algo the make an email from the entered key and then make a user from the entered key, then compare those 2 to the user\email u entered.
i would make a keygen to proove it but i dont have my c installed.
