Discussion and comments
| Iñaki Viggers 17. Jul 2008 | 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"? |

| PeterPunk 17. Jul 2008 | @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 |
| costy 17. Jul 2008 | @ Iñaki Viggers PeterPunk and TiGa have reason. Anyway I suggest to explain this in the faq. |
| Iñaki Viggers 17. Jul 2008 | OK, seen that way I get your point, as it is more explicit than just saying "is considered patching". |
| costy 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. |
| TiGa 17. Jul 2008 | 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? Crackmes.de 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. |
| ~misunderstood~ 19. Jul 2008 | @ 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! |
| Zaphod 19. Jul 2008 | ~misunderstood~, I don't think it was such a bad idea to hide the main method, which would normally show up in PeID :) |
| ~misunderstood~ 19. Jul 2008 | @Zaphod 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. |
