TiGa rejected arguing that self-keygenning is considered patching.

Well, Patching rather means modifying the crackme so that it always jumps to success message. On the other hand Self-keygenning provides a correct serial to the original crackme and is an example of Code Reutilization.

So now what? do we have to type by ourselves hundreds/thousands of opcodes just so a solution doesn't be considered "patching"?

@Iñaki: for keygenning you need to understand the algo, but for self-keygenning you only need to know how patch the file to show the valid password.

PD: Sorry for my english

@ Iñaki Viggers
PeterPunk and TiGa have reason. Anyway I suggest to explain this in the faq.

OK, seen that way I get your point, as it is more explicit than just saying "is considered patching".
17. Jul 2008
Yeah. One time I sended a selfgen. It was rejected by TiGa. I didn't understand becoude he just said "is considered like patching" but I have to admit he then gave me a good explaination privately. It's a good moderator.

ok, I added a new question to the FAQ:
The author of the crackme asked for NO PATCHING in big capital letters, can I submit a patching solution anyway? is not a warez site, it's a place to learn reverse-engineering.
Solving a crackme is not that important, it's what you learn during the solving process that is important.

@ manatails007
I think your KeygenME is ok for the beginning, but maybe you should think about a more original method of CALCULATING your serial next time (and the relation between name and serial)... ;)
Anyway, keep on reversing/coding!

~misunderstood~, I don't think it was such a bad idea to hide the main method, which would normally show up in PeID :)

hhmmm well... ok, that´s a good point at least ;).
another good one is the way the correct/wrong - messages to be put out, so that searching for textstrings does not help immediately.
but there should have been put more creativity into the creation of the serial.
