In general, how do I crack a program, or where can I learn how to crack a .exe program?

If this is far too hard, would it be easier to learn how to create a sort of key generator for a program?

I need to know for autofighter.org's autofighter for rs.
I needz teh latest version Razz

You need a disassembler, basic assembly knowledge, and reverse engineering knowledge.

Also, it's not possible to keygen AutoFighter; because serials are validated by the server.

GAH!
are you serious?!
Well I learned alot more about creating a key gen for this stuff.
For some reason, I can't view the source code with a VB disassembler, it says its not a VB6 file!
If I could get my hands on the source, isn't there a list of serial's that will work that checks if it is validated?

That's because it isn't a vb6 file Confused . I didn't know there was such thing as a vb disassembler.. are you trying to view the code?

yes, I am. In the code I should be able to find some sort of algorithm to generate keys, or the pre programmed keys that are in the program.
I could have sworn its a vb5/6 file, as that is my dissassembler's use. Plus, on the site, it says it was programmed in VB under the hood? Is there such a dissembler for that?

EDIT-- also, I was able to dissassemble the code for the previous version of Autofighter, but I guess the newest version had been programmed with a new language? Neutral

A disassembler doesn't let you view code. VB6 can interpret another VB6 file because VB is an interpreted language.

so what angle should I go from to get the code? I NEED to find the algorithm to create a key gen....

You can't get a program's code (unless it's written in assembly Razz). To find the algorithm you need to disassemble & debug it.

That's where basic debugging, ollydbg, asm, & reverse engineering knowledge comes in (see post at top).

You won't be able to crack the latest autofighter. It's packed with Themida.

The new AutoFighter is packed with Themida, that's why you couldn't disassemble it.

Edit: Oops, didn't see Willy already told you.

Ever hear about un-packing it? QUnPack is what I use.
